Abstract
Electroplating of aluminum may be utilized to form electrodes for solar cells. In contrast to expensive silver electrodes, aluminum allows for reduced cell cost and addresses the problem of material scarcity. In contrast to copper electrodes which typically require barrier layers, aluminum allows for simplified cell structures and fabrication steps. In the solar cells, point contacts may be utilized in the backside electrodes for increased efficiency. Solar cells formed in accordance with the present disclosure enable large-scale and cost-effective deployment of solar photovoltaic systems.
