ABSTRACT:
A dot-junction photovoltaic cell using high absorption semi-conductors increases photovoltaic conversion performance of direct band gap semi-conductors by utilizing dot-junction cell geometry. This geometry is applied to highly absorbing materials, including In.sub.x-1 Ga.sub.x As. The photovoltaic cell configured to be separated into a thin active region and a thick, inactive substrate, which serves as a mechanical support.
