Woord vooraf van de programmaleider Introduction The Nano-photovoltaics (NPV) programme started in July 2009, and is composed of research in the groups headed by Mischa Bonn, Jaime Gómez Rivas and Albert Polman, that collaborate to develop novel photovoltaic energy conversion concepts based on nanotechnology. The programme focuses on the study of novel physical concepts and insights. In some cases prototype devices are also made. The programme's research topics are: • light trapping in thin-film solar cells using plasmonic nanostructures • harvesting excitons in novel quantum dot solar cell geometries • light trapping and conversion in semiconductor nanowire solar cells The NPV programme finances a total of 6 PhD students/postdocs, 1 guest and 1 technician. All positions have been filled and three PhD defenses are planned for the Fall of 2013. In 2012, a total of 13 articles appeared from researchers funded by the NPV programme and two patent applications were filed. Research highlights in 2012 In 2012 we presented a new concept for enhanced light coupling into high-index substrates using resonant dielectric Mie scatterers (Nature Comm. 3, 692 (2012)). In this geometry, light is trapped into resonant modes in high-index surface-integrated nanocavities and preferentially scattered into the substrate. This novel concept provides an interesting alternative to plasmonic light scattering, which suffers from absorption losses. With collaborators from Eindhoven University, we investigated how TiO2 resonant scatterers can be combined with efficient Al2O3 surface passivation layers made using atomic-layer deposition. Next, we demonstrated using numerical simulations that suitably designed Mie scattering dielectric light trapping layers can yield an ultrathin (10 µm) Si solar cell with an efficiency of 20%. With collaborators at the Helmholtz Institute we designed a new light trapping geometry for CuInGaSe2 thin-film solar cells that strongly enhances both the blue and red response. We also demonstrated the important contribution of scattering from resonant dielectric nanostructures in backpatterned thin-film solar cells. Together with Caltech we carried out experiments aiming to demonstrate a plasmo-electric effect in resonant plasmonic nanostructures. Using ultrafast spectroscopy we established the efficiency of hot carrier multiplication in singlelayer graphene (Nature Phys. 9, 248 (2013)). We demonstrated photon-to-electron energy conversion efficiencies exceeding 70 % for wavelengths covering the visible part of the solar spectrum. We have also studied photoconductivities on one-dimensional graphene nanoribbons and nanotubes and found that carrier dynamics and conductance on those systems resemble the characteristics for polymers. Electron transfer from semiconductor nanocrystals to a mesoporous oxide phase has been quantitatively surveyed using optical pump-THz probe spectroscopy as a function of donor-acceptor coupling strength. Two different sets of molecular linkers of variable length anchoring the nanocrystal to the oxide were analyzed. The results proved that electron transfer rates can be modeled by a pure tunneling process through a barrier potential introduced by a given molecular bridge. We found that unsaturated n-phenylene bridges are better wires (allow faster electron transfer processes) than those based on n-methylene units. A fundamental aspect of semiconductor nanowires for photovoltaic applications is their highly directional optical response associated to their inherent geometrical anisotropy. In an effort to
-2-
understand the directional emission and absorption by nanowires we have developed a timereversed Fourier microscope. This instrument allows us to measure the direction of emission of individual nanowires by imaging the back focal plane of a microscope objective. In this way we have demonstrated the nanoantenna-like emission of nanowires (Nano Lett. 12, 5481 (2012)). By time reversing the optical path in the Fourier microscope, we can illuminate individual nanowires with plane waves of defined wavevectors and collect the emission or measure the photocurrent if the wires are contacted. With this unique instrument we have demonstrated that Mie theory, widely used in the field of nanowire photovoltaics, fails to describe the absorption for angles of incidence close to the nanowire axis. The effect dominating the absorption efficiency for these angles is the coupling of the incident light to guided modes in the nanowire. We have also investigated the emission from quasi 2D photonic crystals of nanowires using Fourier microscopy (Phys. Rev. B 86, 245303 (2012)), and demonstrated the excitation of Bloch modes in the periodic structure and the control of the emission by infiltration of the photonic crystal with liquids. NPV meetings and conferences In 2012, the NPV programme held progress meetings on 8 March and 18 December.
NPV team meeting on 18 December 2012 Albert Polman was co-chair of the Symposium Optical nanostructures and advanced materials for photovoltaics at the OSA Renewable Energy and the Environment Conference in Eindhoven November 1114, 2012. In the Fall of 2012, AMOLF, UvA and UV started the Amsterdam solar energy initiative SOLARDAM, a joint research collaboration focusing on harvesting energy for the sun using photovoltaics, photocatalysis and photosynthesis. Over 100 scientists are active in solar energy research in Amsterdam. A workshop was held on 16 November 2012.
Senior staff in solar energy research at VU, UvA and AMOLF assembled for a workshop on 16 November 2012. Awards A major highlight in 2012 was the award of the ENI Renewable and Non-conventional Energy Prize to Albert Polman and his collaborator Harry Atwater (Caltech) for their research on highefficiency solar cells based on nanophotonic design. The ENI prize is the largest international prize
-3-
in Renewable Energy Research. It was awarded by the president of the Italian Republic, Giorgio Napolitano, in a special ceremony Rome on 15 June 2012.
Albert Polman, president Napolitano, and Harry Atwater at the ENI Award ceremony on 15 June 2012 in Rome The article by Spinelli et al., published in J. Opt. 14, 24002 (2012) was selected by the editors as one of the ‘Highlights of 2012’ of the Journal of Optics. Papers are chosen on the basis of referee endorsement, novelty, scientific impact and broadness of appeal. Another highlight of the NPV programme was the news that the review article Plasmonics for improved photovoltaic devices, by H.A. Atwater and A. Polman, Nature Mater. 9, 205 (2010), was cited more than 1000 times since it appearance in 2011. Knowledge transfer Philips Research The collaboration with Philips Research on Substrate Conformal Imprint Lithography (SCIL) has been continued (Nature Comm. 3, 692 (2012)). The presence of the group of Gómez Rivas at the Philips Campus lead to several other exchanges with Philips Research on photovoltaics. Philips has also expressed interest in using experimental techniques and structures developed within the NPV programme for the complementary process to photovoltaics, i.e., electroluminescence for application in LEDs. ECN The collaboration with the Energy Research Center of the Netherlands (ECN) has been formalized through a research and intellectual property exchange agreement. Projects are currently being pursued with ECN on light trapping in crystalline Si solar cells (with Frank Lenzmann), and amorphous Si solar cells (with Wim Soppe). TKI Solar AMOLF has joined the TKI Silicon Competence Center (SCC), a collaborative effort of ECN, Tempress, Levitech, ASMI, Eurotron, Roth en Rau and TUD. The SCC is a facility for solar cell development and testing, in which AMOLF will collaborate with the industrial partners on specific characterization topics.

Follow-up programme LMPV Based on the success of the NPV programme, a FOM Focus group was established at AMOLF entitled Light management for new photovoltaic materials. This enables the start of a major research programme in photovoltaics that will serve as the follow-up of the NPV programme. Devices While the NPV programme focuses on the physical aspects of novel nanophotovoltaic light management strategies, several demonstrator devices and geometries were developed in 2012: 1. plasmonic thin-film amorphous Si solar cells 2. transparent conducting nanowire network coating 3. quantum dot sensitized solar cells based on CdSe/TiO2 and PdSe/SnO2 4. dye-sensitized solar cells based on CdSe/TiO2 and PdSe/SnO2 5. nanopatterend CuInGaSe2 thin-film solar cells 6. broadband omnidirectional silicon nanowire antireflection coating 7. broadband omnidirectional Mie scatterer antireflection coating Outreach and other activities In the Fall of 2012, Jaime Gómez Rivas, Albert Polman, and Enrique Canovas lectured in a fullsemester course in the Advanced Materials and Energy Master programme of the University of Amsterdam. PhD students from the NPV programme served as teaching assistants. Students also received a lab-tour at AMOLF. Many reports on the NPV programme appeared in the printed press and on radio and tv. Conclusion With a significant number of publications, awards, and many other highlights, 2012 was a very successful year for the Nanophotovoltaics programme!

Concise programme description a. Objectives The objective of this programme is to exploit recent advances in nanoscience and nanotechnology to realize solar cells with increased efficiency and/or lower materials costs. The programme is based on exploiting enhanced light absorption and carrier collection in ultrathin film, nanowire and quantum dot solar cells. The programme has four key focal points: 1. Enhanced light coupling into ultra-thin film and low-dimensional inorganic semiconductor absorber layers using plasmonic and photonic nanostructures; 2. Design and synthesis of quantum dot multijunction and multispectral absorber layers with enhanced carrier collection efficiency; 3. Enhanced light coupling using nanowire graded-index surfaces; 4. Integration of these concepts in novel nanoscale solar cell geometries. The programme focuses on achieving fundamental understanding of light-matter interaction in novel solar cell geometries at sub-wavelength length scales and will lead to entirely new design concepts in photovoltaics. b. Background, relevance and implementation The development of renewable energy sources is of great importance to achieve a society with a sustainable energy supply. Photovoltaics has the promise of a clean and practical technology that can be applied at large scale. However, the costs of photovoltaic energy conversion presently exceeds significantly the costs of 'conventional' electricity. To solve this problem, breakthrough developments are required. The goal of this programme is to investigate such possible breakthroughs, focussing on the development of novel solar cell geometries with increased efficiency or with reduced fabrication costs. The programme brings together three research groups that combine a unique complementary expertise in nanophotonics, plasmonics, semiconductor nanowire opto-electronics, and ultra-fast and THz spectroscopy in low-dimensional systems. It is carried out within an international network of collaborators at the California Institute of Technology, Stanford University, and the
-7-
Australian National University. While the programme will focus on fundamental concepts, prototype devices will be fabricated as well. This will facilitate transfer of knowledge to the photovoltaics industry.

Bijlage bij de outputgegevens Dit voortgangsverslag met de outputgegevens is tot stand gekomen aan de hand van de input van de onderzoekers van zowel de FOM-instituten als de universitaire werkgroepen. Dit verslag bevat een dwarsdoorsnede van de geleverde input. De programmaleider heeft de output akkoord bevonden en een woord vooraf geschreven over de voortgang van het programma. Bij alle gegevens staat een datum of een periode. Omdat er enige tijd zit tussen de totstandkoming en publicatie van dit overzicht, geeft dit dus geen actueel beeld. Doel is dan ook de voortgang en bereikte resultaten te laten zien uit het peiljaar. Voor de volledigheid staat hieronder de originele vragenlijst voor de onderzoekers vermeld, plus het relevante deel van de e-mail met instructies. AMOLF en DIFFER hebben een vragenlijst op maat gekregen die op details afwijkt van deze versie. Geachte professor, Hierbij ontvangt u een formulier voor het opgeven van de output van het jaar 2012. In het formulier staan de titel van het project, het projectnummer en de FOM-medewerker(s) al vermeld. U kunt eventueel betrokken U(H)D's ook opgeven in het formulier. We verzoeken u deze informatie terug te zenden vóór 1 februari 2013. Lees deze e-mail in zijn geheel aandachtig door voor de tips bij het invullen en sla regelmatig uw bestand op! Achtergrond outputverzameling Ieder jaar verzamelt FOM de output van alle projecten die bij FOM lopen. De informatie die we daaruit verkrijgen gebruiken we om te voldoen aan de verplichting aan NWO om te rapporteren over het totaal aantal publicaties, proefschriften, octrooien, etc. Daarnaast gebruiken we de informatie om tabellen in het Jaarboek van FOM te kunnen weergeven. Ook wordt aan de werkgemeenschapscommissies een jaarlijks outputverslag gestuurd waarin in detail over alle lopende projecten binnen de FOM-programma's wordt gerapporteerd. Op de website komen rond de zomer de voortgangsverslagen die jaarlijks in de werkgemeenschapscommissies besproken worden, beschikbaar als download bij de fact sheets van de FOM-programma's. Welke output opgeven? Wij verzoeken u alleen output op te geven die toegeschreven kan worden aan het betreffende project en alleen uit het peiljaar. Dus het verzoek is om alleen de output van de FOM-medewerkers die op het formulier staan op te geven. Alvast mijn hartelijke dank voor uw medewerking, Met vriendelijke groet, Gabby Zegers
