SEMI-TRANSPARENT THIN-FILM PHOTOVOLTAIC DEVICE PROVIDED WITH AN OPTIMIZED METAL/NATIVE OXIDE/METAL ELECTRICAL CONTACT

摘要

A thin-film semi-transparent photovoltaic device comprising: a plurality of active photovoltaic zones, having a surface S₅, formed of: a transparent substrate; a front electrode formed of a transparent electroconductive material arranged on the transparent substrate; an absorber made up of one or more photoactive thin layer(s); a rear electrode formed of a stack of at least: a conductive metal layer; and a native metal oxide layer having a nanometric thickness. The device additionally includes a plurality of transparent zones separating at least two active photovoltaic zones; and a metal reconnection layer having a contact surface S to the rear electrode, wherein the ratio R_a=S/S₅ between the contact surface S of the metal reconnection layer and the surface S₅ of an active photovoltaic zone is such that 0.2%a<2%.
