摘要： 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.

摘要： Methods and systems for removing impurities from an electrolytic salt are disclosed. After removal of impurities from the salt, the salt can be subjected to electrorefining to produce high-purity materials, for example silicon. Impurities are removed from the salt using a system that includes a first working electrode, a counter electrode, and at least one reference electrode. A second working electrode can also be utilized. The salt may be utilized in an electrorefining system, for example a system operated in a single phase or multiple phase operation to produce high-purity materials, such as solar-grade silicon.
