A new type solar cell consisting of dye-redox system have been developed. I
nstead of single dye, mixture of two dyes along with a reducing agent, EDTA
was taken in the illuminated compartment of an ii-shaped cell in which I-/
I-2 redox couple in the dark compartment are separated by glass membrane (P
orosity 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 compar
ison to the cell with single dye. (C) 1999 Elsevier Science S.A. All rights
