A New Method to Determine the Optimum Load of a Real Solar Cell Using Special Trans Function Theory (STFT)

Naorem Santakrus Singh, Amit Jain, Avinashi Kapoor


An analytical expression for optimum load for a real solar cell, having resistive and current leakage losses, has been obtained using special trans function theory (STFT) for solving the transcendental current-voltage relationship. Theoretically calculated value using STFT is compared with the experimental data as well as the values obtained by other methods. Impact of series resistance and shunt resistance on optimum load is also studied. The numerical results indicate that STFT method has the best accuracy over other available methods in literature.
