Efficient organic dye sensitized solar cells based on modified sulfide/polysulfide electrolyte

An energy conversion efficiency of up to 5.24% has been attained, under AM 1.5 G illumination for a new dye-sensitized solar cell using TH305, as a low cost organic dye, ((CH3)4N)2S/((CH3)4N)2S2, as an organic electrolyte and CoS as counter electrode.
