Thin-film solar cell comprises substrate, transparent, electrically conductive front electrode layer provided on light-facing side, and semiconductor layer

摘要

A thin-film solar cell comprises a substrate (1), a transparent, electrically conductive front electrode layer (2) provided on light-facing side (hv), and a semiconductor layer (3). The semiconductor layer is electrically connected to back electrode layer (15). The back electrode layer includes a reflective sublayer (6) and a structured layer (5). The structured layer for structuring reflective back electrode sublayer is coated with a part of the rear electrode layer. An independent claim is also included for a method for producing thin-film solar cell, which involves depositing reflective back electrodes sublayer on structured layer through sol-gel process, where structured layer is provided with transparent electrically conductive back electrode layer, semiconductor layer or substrate with a printed plate.
