Effect of Coordination Sphere Geometry of Copper Redox Mediators on Regeneration and Recombination Behavior in Dye-Sensitized Solar Cell Applications

Shaik Mohammed Zakeeruddin, Yasemin Saygili, Jacques-Edouard Moser, Ulf Anders Hagfeldt, Joël Teuscher, Fabrizio Giordano, Marina Freitag, Marko Stojanovic, Jan Tiepelt

The recombination of injected electrons with oxidized redox species and regeneration behavior of copper redox mediators are investigated for four copper complexes, [Cu(dmby)2]2+/1+ (dmby = 6,6′-dimethyl-2,2′- bipyridine), [Cu(tmby)2]2+/1+ (tmby = 4,4′,6,6′ ...

Molecular engineering of low-cost, efficient, and stable photosensitizers for dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Felix Thomas Eickemeyer, Lukas Pfeifer, Marina Freitag, Jing Gao, Zhongjin Shen

The cost, stability, and photovoltaic performance of photosensi-tizers play a key role in the commercialization of dye-sensitized solar cells (DSCs). Herein, three novel sensitizers termed ZS10, ZS11, and ZS12 are described based on the simple chemical str ...

Liquid State and Zombie Dye Sensitized Solar Cells with Copper Bipyridine Complexes Functionalized with Alkoxy Groups

Michael Graetzel, Shaik Mohammed Zakeeruddin, Rosario Scopelliti, Jacques-Edouard Moser, Ulf Anders Hagfeldt, Joël Teuscher, Yasemin Saygili, Marina Freitag, Hui-Seon Kim, Marko Stojanovic

Copper redox mediators can be employed in dye sensitized solar cells (DSCs) both as liquid electrolytes or as solid state hole transport materials (HTMs). The solid state devices that employ copper complex HTMs can be simply obtained by solvent evaporation ...
