COMPARATIVE-STUDY OF ORGANOMETALLIC DYES AND FULLERENES IN DYE-SENSITIZED TIO2 SOLAR-CELLS

Dye-sensitized cells differ from the conventional semiconductor device s in that they separate the function of light absorption from charge c arrier transport. The device is based on a 10 mu m thick, optically tr asparent film of titanium dioxide particles a few nanometers in size, coated with a monolayer of charge-transfer dye to sensitize film for l ight harvesting. The comparative study of solar cells with different o rgano-metallic dyes and fullerenes as sensitizers of TiO2, showed diff erent possibilities for the construction of the second generation sola r cells.
