COMPOSITIONS AND PROCESSES FOR FORMING PHOTOVOLTAIC DEVICES

摘要

Methods and compositions for making photovoltaic devices are provided. A metal that is reactive with silicon is placed in contact with the n-type silicon layer of a silicon substrate. The silicon substrate and reactive metal are fired to form a silicide contact to the n-type silicon layer. A conductive metal electrode is placed in contact with the silicide contact. A silicon solar cell made by such methods is also provided.
