PHOTOVOLTAIC SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

A semiconductor device has a plurality of unit photovoltaic elements arranged on a substrate and connected to each other in series. The photovoltaic device includes first semiconductor layers with low resistivity formed on a high-temperature-resistant insulating substrate and spaced apart at a predetermined interval and second semiconductor layers selectively formed on corresponding first semiconductor layers so that a part of the respective first semiconductor layer is exposed. The second semiconductor layer is not in contact with the first semiconductor layer of an adjacent unit photovoltaic element. An electrode formed on the second semiconductor layer is in contact with the first semiconductor layer of the adjacent unit photovoltaic element. As a result, there is provided a photovoltaic semiconductor device comprising a plurality of unit photovoltaic elements connected to each other in series with high conversion efficiency and which is not easily degraded by light irradiation.
