Aggregates of plasmonic nanoparticles for broadband light trapping in dye-sensitized solar cells
Metallic nanoparticles (NPs) have not been effective in improving the overall performance of the cells with micrometer-thick absorbing layers mainly due to the parasitic optical dissipation in the metal. Here, using both experiment and theory, we demonstra ...
Iop Publishing Ltd2016Comparison of LPCVD and sputter-etched ZnO layers applied as front electrodes in tandem thin-film silicon solar cells
Christophe Ballif, Franz-Josef Haug, Grégory Bugnon, Michael Elias Stückelberger, Etienne Antoine Julien Moulin
Aluminum-doped zinc oxide (ZnO:Al) layers deposited by sputtering and boron-doped zinc oxide (ZnO:B) layers deposited by low-pressure chemical vapor deposition (LPCVD) are well-established materials for front electrodes in thin-film silicon solar cells. In ...
Elsevier2016Energy Yield and Electricity Management of Thin-Film and Crystalline Silicon Solar Cells
In the case of high photovoltaic (PV) penetration into the electricity grid, the energy produced by a PV system that is effectively used (useful energy) depends on the energy yield and on how this energy is managed to avoid detrimental effects occurring at ...
EPFL2016Towards stable and commercially available perovskite solar cells
Solar cells employing a halide perovskite with an organic cation now show power conversion efficiency of up to 22%. However, these cells are facing issues towards commercialization, such as the need to achieve long-term stability and the development of a m ...
Nature Publishing Group2016Comparison of amorphous silicon absorber materials: Kinetics of light-induced degradation
Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Mathieu Gérard Boccard, Michael Elias Stückelberger, Yannick Samuel Riesen, Adrian Billet
We investigate the influence of the deposition parameters for intrinsic amorphous silicon absorber layers on light-induced degradation (LID) of thin-film silicon solar cells. The focus is on absorber layers with different bandgaps: on one side, solar cells ...
Wiley-Blackwell2016Maximal absorption regime in random media
Olivier Martin, Christian Santschi, Volodymyr Koman
Efficient optical energy transfer is key to many technologies, ranging from biosensing to photovoltaics. Here, for the first time we show that by introducing a random medium with appropriate filling factor, absorption in a specific volume can be maximized. ...
Optical Society of America2016Improving charge collection with delafossite photocathodes: a host–guest CuAlO2/CuFeO2 approach
Kevin Sivula, Nestor Guijarro Carratala, Yang Li, Mathieu Steven Prévot
p-Type delafossite CuFeO2 has recently been reported as a promising candidate for direct photoelectrochemical solar water reduction in alkaline conditions. However, despite its favorable optical band gap energy and light absorption, this material suffers f ...
Royal Soc Chemistry2016Silver versus white sheet as a back reflector for microcrystalline silicon solar cells deposited on LPCVD-ZnO electrodes of various textures
Christophe Ballif, Franz-Josef Haug, Mathieu Gérard Boccard, Etienne Antoine Julien Moulin
We compare the performance of two back reflector designs on the optoelectrical properties of microcrystalline silicon solar cells. The first one consists of a 5-mu m-thick low-pressure chemical vapor deposition (LPCVD)-ZnO electrode combined with a white s ...
Wiley-Blackwell2015Efficient cell pairing in droplets using dual-color sorting
The use of microfluidic droplets has become a powerful tool for the screening and manipulation of cells. However, currently this is restricted to assays involving a single cell type. Studies on the interaction of different cells (e.g. in immunology) as wel ...
