Solar cells based on dyes

From early developments to recently developed stages of solar cells have be en discussed in details, considering the effect of different parameters. In this paper, primitive photoelectrochemical (PEC) cell and PEC cell with Fe -thionine and different dyes-reducing agent have been reviewed. Solar cell with phenazine dyes have also been pointed out separately since these dyes give more output in solar cell. The use of inorganic semiconductor electrod e (e.g. SnO2, In2O3 and ZnO) and utilization of semiconducting properties o f organic dyes in PEC cell have been mentioned. Furthermore, utilization of surfactant media for storage of solar energy and production of hydrogen fr om solar cell using dye are also included. (C) 2000 Elsevier Science S.A. A ll rights reserved.
