Abstract
In accordance with one aspect of the present disclosure, a solar photovoltaic device is disclosed. The semiconductor material of the solar photovoltaic device is a heterostructure of two different binary compounds of the same metal. One or both of the two different binary compounds of the same metal are doped so that they have a conduction band edge offset of greater than about 0.4 eV. The binary compound acting as the optical absorbing material of the solar photovoltaic device has a bandgap of about 1.0 eV to about 1.8 eV.
