Reconfigurable power management for monolithic CMOS-on-Photovoltaic under partial and complete shading

摘要

The Photovoltaic (PV) cells of a module can be made to operate in various load and lighting condition by using switches to connect in series or parallel for various load requirements in the field, such as high voltage and low current versus high current and low voltage. Compared to having external switches monolithic CMOS-on-PV cells improves the module efficiency by providing better reliability and lifetime. In this paper, a partial and complete shading detection algorithm is presented. Also, a model for calculating the output current and voltage equation for the monolithic CMOS-on-PV cell is presented.
