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.pdfEngineering, electrical and electronicJournal Article1558-0563https://doi.org/10.1109/LED.2020.2995924545436900045Q2NOIR02345
