The overall solar-to-electric energy conversion efficiencies in solar simulators, and the incident monochromatic photon-to-current-efficiencies (IPCE) was measured for a selection of molten salt electrolytes to reveal their possible use as electrolytes in dye-sensitized nanocrystalline solar cells (DNSC). The IPCE results of (Et2MeS)I and (Bu2MeS)I were stable above 55% from 400 to 550 nm and then decreased on the red side of the spectra. The addition of iodine to (Bu2MeS)I and (Bu2EtS)I indicated increasing IPCE values at 520-540 nm; from 55 to 60% and 38 to 46%, respectively. (Te2MeS)I, (Bu2MeS)I, and (Bu2EtS)I showed good conducting abilities at ambient conditions and provided good light-to-electricity conversion efficiencies while used as electrolytes in DNSC. The liquid electrolytes (Et2MeS)I provided the highest conversion efficiencies at room temperature.
