Mechanoperovskites for Photovoltaic Applications: Preparation, Characterization, and Device Fabrication

Pankaj Kumar Yadav, Daniel Prochowicz

Hybrid organic-inorganic metal halide perovskites (MHPs) have emerged as excellent absorber materials for next generation solar cells owing to their simple solution-processed synthesis and high efficiency. This breakthrough in photovoltaics along with an a ...

Efficient electron transfer and reduced recombination with Nd:YAG laser scribing for high-efficiency quantum dot-sensitized solar cells

Minkyu Son

Inefficient charge transfer and charge recombination are critical but challenging issues that restrict the power conversion efficiency (PCE) of quantum-dot-sensitized solar cells (QDSSCs). These issues must be addressed to boost the performance of QDSSCs. ...

Lanthanides in Solar Energy Conversion

Jean-Claude Bünzli, Anne-Sophie Chauvin

Solar energy represents an abundant (1000 W·m-2) and seemingly cheap source of energy. One way to tap it is to transform light into electricity with photovoltaic devices. Single junction solar cells presently reach 32% conversion yield under 1-sun illumina ...

A quinoxaline-fused tetrathiafulvalene-based sensitizer for efficient dye-sensitized solar cells

Michael Graetzel, Chenyi Yi, Michele Cascella, Martin Peter Bircher, Jiabao Yang

A new quinoxaline-fused tetrathiafulvalene-based sensitizer has been prepared and characterized. The resulting power conversion efficiency of 6.47% represents the best performance to date for tetrathiafulvalene-sensitized solar cells. ...

Molecular gelation of ionic liquid-sulfolane mixtures, a solid electrolyte for high performance dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jean-David Décoppet, Thomas Moehl

Cyclohexanecarboxylic acid-[4-(3-tetradecylureido)phenyl]amide is an efficient gelator to solidify ionic liquid electrolytes. In this paper we apply this low molecular weight gelator to solidify the newly prepared sulfolane based ionic liquid electrolyte. ...
