Abstract
A unique multiband spectrum solar cell implemented using a cross dichroic prism with the capability to separate incident solar radiation into three visible or infrared spectral components or bands using two dichroic filters is described. Inexpensive thin film solar cells can be deposited directly onto the prism outer surfaces acting as a substrate. The operational spectrum combined by three cells can be designed to cover most of the visible light and infrared (300 nm to 1100 nm) regions providing maximized power output. Manufacture of an elongated (length extended) version is described to increase photovoltaic surface area and create a sub module with space efficient packing into an array supporting a flat panel form factor. Finally, a complete solar panel system is described based upon an array of sub modules combined with power conversion electronics.
