<p>A solar cell formed from a semiconductor having a relative wide band-gap Eb, characterised by a multi-quantum well system incorporated in the depletion region of the cell, in which the quantum wells comprise regions of semiconductor with a smaller band gap separated by small amounts of the wider band-gap semiconductor (Eb) so that the effective band-gap for absorption (Ea) is less than Eb.</p> |
