✦ Synopsis
A-t-A kinetic model is prcocnted which can explain the variation of the photovoltage with mdox potmtiak. This involves ekctron tmnsfer mactious and electron-hole raxm~bi~tion at a small-bax+gap aemi~~~ndu&or awface in contact with one+?quivslent redox &ems, Experiments dthatthe fluetuatiug energy level umeept can satisfactorily deacxibe the dmrge tram&r @roeuqs st iUusx&Wed Cxmpmui-dlmetori+, like MO&r .an~I WS+. whiob control the photovo&age. ,?+kmlatim &ok& high srrrfia~~ti~ofrrPPs~bc~inth~~t~.~jar~ofthtpattncialdropinttfe Hdmholtx doupk layer occur only if inversion layers with very high surface concentrations of minority caniers are obtaiaal.
