Abstract

See full text

A thin film solar cell and process for forming the same. The solar cell includes a bottom electrode, semiconductor light absorbing layer, and top electrode. Interconnects may be formed between the top and bottom electrodes by electrochemical plating of conductive materials in recessed regions formed between the electrodes. In some embodiments, the conductive materials may be optically opaque metals having non-light transmissive properties. The interconnects are highly conductive and minimize the thickness of the top electrode layer, thereby enhancing light transmission and cell energy conversion performance.
