A Selenium‐Based Cathode for a High‐Voltage Tandem Photoelectrochemical Solar Cell

Abstract

High voltage: A selenium-based photocathode has been developed for a photoelectrochemical solar cell with a high open-circuit voltage Voc of 318 mV and an efficiency of 0.34 %. A higher Voc of 940 mV was realized in a tandem solar cell with a conventional N719 dye-sensitized photoanode, giving an efficiency of 0.98 %.
