An alternative ionic liquid based electrolyte for dye-sensitized solar cells

摘要

An ionic liquid based,environmentally friendly electrolyte LiI(C_2H_5OH)_4-I_2 was used as the electrolyte to fabricate dye-sensitized solar cells(DSSC)with energy conversion efficiency of 4.9under AM 1.5(100 mW cm~(-2))irradiation.In the last decade,dye-sensitized solar cells(DSSCs)have been investigated intensely because of their low cost,high energy conversion efficiency and potential for practical application.Several kinds of DSSCs have been fabricated by using different electrolytes.
