Solution processable, cross-linked sulfur polymers as solid electrolytes in dye-sensitized solar cells

Abstract

Inverse-vulcanized polymeric sulfur has been prepared and utilized for solid-state dye sensitized solar cells. A power conversion efficiency of 1.5% was recorded with a short-circuit current of 4.1 mA cm⁻² and an open-circuit voltage of 0.75 V under standard AM 1.5G illumination (1000 W m⁻²). The results in the present study qualify the new polymeric sulfur material as a future candidate as low-cost, hole-transport material for solid-state dye-sensitized solar cells.
