High-temperature photovoltaics and electrochemical cell combine to advance solar power
Despite continual improvements in efficiency, silicon-based solar cells are hampered by the fact that they only deliver power when the sun is shining and that their efficiency falls off markedly at temperatures over 100° C (212° F). To address these limitations, scientists at TU Wien in Vienna have combined perovskite-based solar cells that work at high temperatures with an electrochemical cell that allows the energy from ultraviolet light to be stored chemically.

Reading a bit further, the perovskite appears to be used as a light-activated catalyst. Talking about oxygen ions passing through a solid electrolyte seems strange.
