Starting with the IV equation for a solar cell: I = I L-I 0 e V V t. V t = n k T q to simplify the notation in the derivation, where kT/q ~ 0.026 volts and n is the ideality factor. The ideality factor varies with operating point. For these equations the correct value to use is the average from V MP to V OC. Power produced by the cell is the product of the voltage and the current, i.e., P = IV ...
