Abstract:
A method of forming a photovoltaic device that includes bonding a substrate to a germanium-containing semiconductor layer with a stressor layer, wherein the stressor layer cleaves the germanium-containing semiconductor layer. At least one semiconductor layer is formed on a cleaved surface of the germanium-containing semiconductor layer that is opposite the conductivity type of the germanium-containing semiconductor layer to provide a first solar cell. The first solar cell absorbs a first range of wavelengths. At least one second solar cell may be formed on the first solar cell, wherein the at least one second solar cell is composed of at least one semiconductor material to absorb a second range of wavelengths that is different than the first range wavelengths absorbed by the first solar cell.
