What is open circuit voltage (V OC) for solar cells?
Open circuit voltage (V OC) is the most widely used voltage for solar cells. It specifies the maximum solar cell output voltage in an open circuit; that means that there is no current (0 amps). We can calculate this voltage by using the open circuit voltage formula for solar cells. We are going to look at this equation.
