A plurality of thin polycrystalline silicon solar cells formed on a ceramic substrate and which are electrically series connected to form a monolithically interconnected submodule. Adjacent solar cells are electrically separated by a vertical trench and electrically connected by interconnects located below the light receiving surface of each solar cell. The submodules are provided with external electrical contacts for electrically connecting into a photovoltaic module assembly.


Provides a monolithically integrated series connected thin polycrystalline silicon solar cell sub-module having no external electrical contacts on the illuminated surface of the cells to reduce device and assembly costs.
