AMORPHOUS SILICON SOLAR BATTERY

摘要

In an amorphous silicon solar battery of the type comprising a flexible and heat resistant substrate, at least two lower electrodes formed on the substrate, an amorphous silicon film formed on the lower electrodes, and at least two upper electrodes formed on the amorphous silicon film, there is provided an inorganic insulating film provided between the substrate and the lower electrodes. The substrate is made of a resin film or a metal sheet. Where the substrate is made of a metal alloy containing Cr, the substrate is heated to selectively oxidize Cr to form a chromium oxide film which is used as a portion of the insulating film. With this construction it is possible to form a plurality of serially connected solar cells on the same substrate.
