The open-circuit voltage (Voc) of a solar cell is defined as the maximum voltage available from a solar cell when no current is flowing. It is determined by the difference in the Fermi levels of the n-type and p-type semiconductor materials within the solar cell. This relationship is critical for understanding solar cell efficiency and performance. The discussion references the educational resource at PV Education for further details on solar cell operation.
