Theoretical parameters related to V OC. The V OC refers to the voltage generated by a solar cell in the absence of current flow due to a broken circuit or exceptionally high resistance. Theoretically, it corresponds to the energy difference between the CBM and VBM levels when considering only the light absorbers in the solar cell.
