A high output solar cell comprises a three-layer semiconductor compound article, the layers being doped in pn1n2 order in the direction of light travel, the pn1 junction being a homojunction and the n1n2 junction being a heterojunction. The doping of the layers is such that "valley-tranferred" or "hot" electrons, so-called, are created in th p and n region secondary electron conduction bands and are transferred to the normal conduction band edge of the n2 heterojunction material and ultimately to an ohmic contact.
