Semi-transparent perovskite solar cells for tandems with silicon and CIGS
Michael Graetzel, Norman Pellet, Julian Burschka
A promising approach for upgrading the performance of an established low-bandgap solar technology without adding much cost is to deposit a high bandgap polycrystalline semiconductor on top to make a tandem solar cell. We use a transparent silver nanowire e ...
Royal Society of Chemistry2015Electrically flat/optically rough substrates for efficiencies above 10% in n-i-p thin-film silicon solar cells
Christophe Ballif, Franz-Josef Haug, Grégory Bugnon, Karin Söderström
Substrates with extremely low roughness to allow the growth of good-quality silicon material but that nevertheless present high light trapping properties are presented. In a first application, silver reflectors are used in single and tandem-junction amorph ...
2012NANO-IMPRINT TECHNIQUE FOR BACK REFLECTOR IN HIGH EFFICIENCY N-I-P THIN FILM SILICON SOLAR CELLS
Christophe Ballif, Franz-Josef Haug, Jordi Escarre Palou, Karin Söderström, Rémi Biron
In this contribution, the replication of nano-textures enhancing the short circuit current of thin film silicon solar cells onto low cost substrates (glass or PolyEthylene Naphtalate (PEN)) is studied. Optical and morphological analysis is performed to ass ...
2010Single and multi-junction thin film silicon solar cells for flexible photovoltaics
This thesis investigates amorphous (a-Si:H) and microcrystalline (μc-Si:H) solar cells deposited by very high frequency plasma enhanced chemical vapor deposition (VHF-PECVD) in the n-i-p or substrate configuration. It focuses on processes that allow the us ...
University of Neuchâtel2009Towards Very Low-Cost Mass Production of Thin-film Silicon Photovoltaic (PV) Solar Modules on Glass
Production volume of PV modules increases at > 35% per year, but one is yet far from making a global impact on energy supply. One of the obstacles is given by the present high production costs of PV modules. A possibility to reduce costs are thin-film PV m ...
