Photoinduced Charge Transfer Dynamics in Blue-Coloured Diketopyrrolopyrrole (DPP) Dye-Sensitized Solar Cells

The inception of push-pull organic dyes utilizing the donor-pi conjugated bridge-acceptor (D-pi-A) motif has created a paradigm shift in the design of efficient nanocrystalline dye-sensitized solar cells (DSSCs), offering control over aesthetic and perform ...

A tandem redox system with a cobalt complex and 2-azaadamantane-N-oxyl for fast dye regeneration and open circuit voltages exceeding 1 V

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Heewon Bahng, Natalie Flores Diaz

A new tandem electrolyte composed of two redox pairs, the organic radical 2-azaadamantane-N-oxyl (AZ) and the well-known redox pair Co(bpy)(3) was investigated in dye sensitized solar cells. Importantly, an increase in V-OC was achieved using the ...
