Abstract
A solar cell for connection in series with a plurality of like cells to provide a solar generator which can produce a desired output voltage. The cell includes a photovoltaic section of compound semiconductor layers stacked on a semiconductor substrate to form a p-n junction and a protective diode section electrically isolated from the photovoltaic section by a p-n junction. The photovoltaic and diode sections are connected in parallel and reverse polarity. The protective diode bypasses current in the solar generator when no light is incident on the photovoltaic section in parallel with the respective diode.
