A 22% Efficient Semiconductor/Liquid Junction Solar Cell—the Photoelectrochemical Behavior of n-WSe2 Electrodes in the Presence of I2/I- in Aqueous Electrolyte
One of the most efficient semiconductor/liquid-junction photoelectrochemical cells (PEC) reported to date is presented. It consists of a SeCl4-grown n-WSe2 single crystal anode, with a 3.1016 cm-3 conduction-band electronic density, and a platinum cathode. Both electrodes are immersed in a 2M KI + 0...

| description | One of the most efficient semiconductor/liquid-junction photoelectrochemical cells
(PEC) reported to date is presented. It consists of a SeCl4-grown n-WSe2 single crystal
anode, with a 3.1016 cm-3 conduction-band electronic density, and a platinum
cathode. Both electrodes are immersed in a 2M KI + 0.005M I2 aqueous electrolyte.
The calculations of the main physical parameters determining the high value (22%) of
the visible light-to-electrical energy conversion efficiency have been carried out. We
particularly show that the lifetime of the photogenerated holes is larger than their
transit time across the space-charge so that the carriers reach the semiconductor
surface, where they can react with the electrolyte, without recombining. |
