ABSTRACT:
Photovoltaic devices are fabricated by forming a thin passivating layer, for example, an oxide layer on a semiconductor material. The passivating layer on the semiconductor material is then contacted with an electrolyte such as an electrolyte containing vanadium ions. The resulting electrolyte/passivating layer/semiconductor (EPLS) structure exhibits excellent solar conversion efficiencies and good stability.
