Determining conversion efficiency between bands

Theoretical limit of conversion efficiency

The maximum value of solar cell conversion efficiency (theoretical limit conversion efficiency) is determined by the size of the band gap. How is this theoretical limit conversion effect derived? A solar cell can be thought of as a power supply with a parallel diode and a short circuit current. As shown in the formula in Fig. 1, if the output voltage P of the load is maximized, the voltage V is proportional to the carrier density of the minority carrier, decreases as the band gap E decreases, and increases as V increases.
