A new, inexpensive, thin film photovoltaic power module

The development of a photovoltaic power generating module is presented. The module is a tandem cell solar generator made using roll-to-roll amorphous silicon alloy thin-film deposition technology. This product is a large-area (1 ft*4 ft) single solar cell that eliminates the distinction between a cell and a module. Device series connections occur externally at the module level, resulting in substantial reductions in fabrication costs.
