We demonstrate cuprous oxide (Cu2O) based screen engineered field effect solar cells with a record breaking efficiency, exceeding 3.486%, for Cu2O based p-n homojunction. In this architecture, CuO nanowire interphase is successfully employed in the Cu2O fabrication by effectively serving as a simultaneous ohmic current collector. These screen engineered field effect photovoltaic principles are essential in developing promising photovoltaics architectures for hard-to-dope materials that, in principle, enable extremely low-cost, high efficiency solar cells.
