Modular interdigitated back contact photovoltaic cell structure on opaque substrate and fabrication process

摘要

A back contacted photovoltaic cell composed of an integrated diode structure of polycrystalline silicon (briefly polysilicon) or in any case of silicon in a at least partially crystalline state, processed according to a so called thin film technology, that is not requiring the use of silicon wafer or of multi micron-thick layers of silicon wafer separated from a mother wafer, and a relative process of fabrication, are disclosed.
