The effect of particle size and conductivity of CuI layer on the performance of solid-state dye-sensitized photovoltaic cells

The conductivity of CuI film was greatly increased by the addition of the thiocyanate salts and the photoenergy conversion efficiency of DSSSCs made with this CuI film as a hole transporting material was greatly improved. The optimum amount of SCN salt for the cell performance was 4–5% to CuI, and a...

More Information
Summary:The conductivity of CuI film was greatly increased by the addition of the thiocyanate salts and the photoenergy conversion efficiency of DSSSCs made with this CuI film as a hole transporting material was greatly improved. The optimum amount of SCN salt for the cell performance was 4–5% to CuI, and an excessive addition declined cell performance in spite of conductivity increasing.
