Abstract

MoS₂ counter electrodes obtained via spin-coating of MoS₂ nanosheets followed by thermal treatment at varied temperatures were used as highly transparent counter electrodes in dye-sensitized solar cells, and the effect of temperatures on electrocatalytic activity as well as overall power conversion efficiency (PCE) of DSSCs was investigated. DSSC with thermally treated MoS₂ at 100°C exhibited comparable PCE of 7.35% to conventional Pt contained DSSC showing 7.53%, whereas cell performance with MoS₂ thermally treated at higher temperature over 300°C showed significant decrease in PCE due to the chemical change of MoS₂ to poor electrocatalytic MoO₃.
