Abstract

CuSCN with enhanced p-type conductivity was prepared by replacing some of the cuprous sites by triethylamine coordinated Cu(I) with concomitant (SCN)₂ doping to introduce more holes. A compound Cu₅[(C₂H₅)₃N]₃(SCN)₁₁ was isolated and well characterized. A 41% enhancement of energy conversion efficiency of the TiO₂/N719/modified CuSCN cell from the best reported value and more than a factor of ten from bare CuSCN was achieved.
