Enhancement in power output of solar cells consisting of mixed dyes

Abstract A new type solar cell consisting of dye-redox system have been developed. Instead of single dye, mixture of two dyes along with a reducing agent, EDTA was taken in the illuminated compartment of an H-shaped cell in which I − /I 2 redox couple in the dark compartment are separated by glass membrane (Porosity G-4). The dyes used for mixed system are of four classes: phenazine, thiazine, xanthene and acridine. Calculated solar energy efficiency (SEE) and other cell characteristics of mixed dye-solar cell is larger in comparison to the cell with single dye.
