A PV cell is essentially a large-area p–n semiconductor junction that captures the energy from photons to create electrical energy. At the semiconductor level, the p–n junction creates a depletion region with an electric field in one direction. When a photon with sufficient energy hits the material in the depletion region.

2.1 Temperature effect on the semiconductor band gap of SCs. Band gap, also known as energy gap and energy band gap, is one of the key factors affecting loss and SCs conversion efficiency. Only photons with energy higher than the forbidden band width can produce PV effect, which also determines the limit of the maximum wavelength that SCs can absorb for power generation [].
