7.35% Efficiency rear-irradiated flexible dye-sensitized solar cells by sealing liquid electrolyte in a groove†
Abstract
We report the feasibility of assembling rear-irradiated flexible dye-sensitized solar cells employing a transparent Ni–Se alloy counter electrode along with a groove stored TiO2 and liquid electrolyte. The flexible device with the NiSe counter electrode and anode at a groove depth of 36 μm yielded a maximum efficiency of 7.35%.
