Facile preparation of micron- and nano-scale textured master for nano-imprinting front electrode in thin-film silicon tandem cells with improved light trapping

Christophe Ballif, Franz-Josef Haug, Etienne Antoine Julien Moulin, Jinhua Huang

This paper reports a facile method to prepare a textured surface with combined micron- and nano-scale surface features, which is used as master for nano-imprinting process to obtain transparent front electrodes in thin-film silicon tandem cells. The micron ...

A Novel Oligomer as a Hole Transporting Material for Efficient Perovskite Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Nicolas Tétreault, Peng Gao, Mohammad Ibrahim Dar, Peng Qin

(Figure Presented) A polytriarylamine-based oligomer is reported as a hole transporting material and its application in solid-state CH3NH3PbI3 based heterojunction solar cells is described. It yields a power conversion efficiency of 12.0% under 99.6 mW cm- ...

Laser-Scribing Patterning for the Production of Organometallic Halide Perovskite Solar Modules

Christophe Ballif, Jun Ho Yum, Arnaud Walter, Sylvain Nicolay, Laurent Fabien Hubert Sansonnens, Julien Claude Bailat, Soo-Jin Moon, Mustapha Benkhaira

Efficiencies of solar cells based on organometallic halide perovskite absorber material have dramatically increased over the past few years. Most of efficiencies reported so far have, however, been obtained on solar cells with very small lab-scale area of ...

Control and Study of the Stoichiometry in Evaporated Perovskite Solar Cells

Michael Graetzel, Nicolas Tétreault, Joël Teuscher

Herein, we present the precise stoichiometric control of methlyammonium lead iodide perovskite thin-films using high vacuum dual-source vapor-phase deposition. We found that UV/Vis absorption and emission spectra were inadequate for assessing precisely the ...

A New Fullerene-Free Bulk-Heterojunction System for Efficient High-Voltage and High-Fill Factor Solution-Processed Organic Photovoltaics

Wolfgang Richard Tress, Fei Zhang, Bo Liu

Small molecule donor/polymer acceptor bulk-heterojunction films with both compounds strongly absorbing have great potential for further enhancement of the performance of organic solar cells. By employing a newly synthesized small molecule donor with a comm ...

Back-Contacted Silicon Heterojunction Solar Cells: Optical-Loss Analysis and Mitigation

Christophe Ballif, Antoine Descoeudres, Bertrand Yves Paul Paviet-Salomon, Matthieu Despeisse, Stefaan De Wolf, Sylvain Nicolay, Loris Barraud, Andrea Tomasi

We analyze the optical losses that occur in interdigitated back-contacted amorphous/crystalline silicon heterojunction solar cells. We show that in our devices, the main loss mechanisms are similar to those of two-side contacted heterojunction solar cells. ...

Efficient and stable large-area perovskite solar cells with inorganic charge extraction layers

Michael Graetzel, Wei Chen, Weiwei Zhang, Yinghui Wu, Jian Liu

The recent dramatic rise in power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) has triggered intense research worldwide. However, high PCE values have often been reached with poor stability at an illuminated area of typically less than 0 ...

Investigation of Interfacial Charge Separation at PbS QDs/ (001) TiO2 Nanosheets Heterojunction Solar Cell

Jacques-Edouard Moser, Lioz Etgar, Elham Ghadiri

In the recent years, the heterojunction solar cells based on quantum dots (QDs) have attracted attention due to strong light absorbing characteristics and the size effect on the bandgap tuning. This paper reports on the kinetics of interfacial charge separ ...
