PHOTOVOLTAIC CELL CIRCUIT.

摘要

A photovoltaic cell circuit (50) is disclosed which comprises a plurality of photovoltaic cells (12) connected in series. At least one switching device (42) is shunted across a group of one or more of the photovoltaic cells (12). The switching device (42) provides a current path for the circuit (50) when light is obstructed from impinging on one or more of the photovoltaic cells (12) across which the switching device (42) is shunted.
