Low-cost and high-performance CoMoS4 and NiMoS4 counter electrodes for dye-sensitized solar cells

Abstract
Porous chalcogels CoMoS4 and NiMoS4 made by a facile solution reaction displayed good electrocatalytic activity in the redox reaction of the I/I3 shuttle. Dye-sensitized solar cells with these ternary compounds as counter electrodes (CEs) showed photovoltaic performance similar to the devices made with noble metal platinum CE (7.46%).
