In situ growth of a MoSe₂/Mo counter electrode for high efficiency dye-sensitized solar cells

Abstract

A facile and economical MoSe2/Mo structure was in situ prepared to replace the currently preferred expensive Pt and FTO counter electrode (CE) in dye-sensitized solar cells. A power conversion efficiency of 8.13% was achieved, which is comparable to that with Pt-sputtered FTO electrode (8.06%).
