Design and Development of Novel Linker for PbS Quantum Dots/TiO2 Mesoscopic Solar cell

Michael Graetzel, Mohammad Khaja Nazeeruddin, Lioz Etgar, Guido Viscardi

A novel bifunctional linker molecule, bis(4-mercaptophenyl)phosphinic acid, is designed to be used in a QDs solar cells. The linker anchors to TiO2 mesoporous film through the phosphinic acid functional group and to the PbS QDs through the two thiol groups ...

Ga3+ and Y3+ Cationic Substitution in Mesoporous TiO2 Photoanodes for Photovoltaic Applications

Michael Graetzel, Aravind Kumar Chandiran, Lioz Etgar

The optoelectronic properties of transparent nanocrystalline TiO2 films were modified by the incorporation of a low level of Ga3+ or Y3+ cations. After optimizing their relative concentration level, we were able to increase in a noticeable manner the power ...

An efficient DSSC based on ZnO nanowire photo-anodes and a new D-pi-A organic dye

Michael Graetzel, Shaik Mohammed Zakeeruddin, Lioz Etgar, Peng Wang

Zinc oxide-titanium dioxide core-shell nanowire dye-sensitised solar cells have been synthesised, making use of a recently developed organic dye and iodide-based electrolyte. We have been able to demonstrate a cell efficiency of 2.53% under AM1.5 for our s ...

Depleted Bulk Heterojunction Colloidal Quantum Dot Photovoltaics

Michael Graetzel, Lioz Etgar

The first solution-processed depleted bulk heterojunction colloidal quantum dot solar cells are presented. The architecture allows high absorption with full depletion, thereby breaking the photon absorption/carrier extraction compromise inherent in planar ...
