HYBRID TRANSPARENT ELECTRODE ASSEMBLY FOR PHOTOVOLTAIC CELL MANUFACTURING

摘要

A photovoltaic cell is described comprising a top transparent electrode, a PV layer, a semiconductor substrate, a bottom electrode, and a metal bus-bar grid assembly deposited on said top transparent electrode. In a preferred embodiment, the top transparent electrode is a thin film of indium-tin-oxide (ITO). The method of manufacturing the PV device or cell includes the steps of: cleaning a preprocessed semiconductor bulk having a PV layer on its top surface; depositing a layer of a transparent conductive film over the top of said PV layer; depositing a metal bus-bar grid assembly over said transparent conductive film; and depositing a metal bottom layer on the bottom surface of said semiconductor bulk.
