Solar cells based on dyes
TLDR
In this paper, primitive photoelectrochemical (PEC) cell and PEC cell with Fe-thionine and different dyes-reducing agent have been reviewed.Abstract:
From early developments to recently developed stages of solar cells have been 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 electrode (e.g. SnO2, In2O3 and ZnO) and utilization of semiconducting properties of organic dyes in PEC cell have been mentioned. Furthermore, utilization of surfactant media for storage of solar energy and production of hydrogen from solar cell using dye are also included.read more
