Which outcome impairs solar cell efficiency because the semiconductor becomes heated?

💡 Explanation

Increasing a solar cell's temperature alters the band gap, and thus its efficiency, because thermal expansion modifies the interatomic spacing, shifting energy levels through the mechanism of lattice dilation; therefore, the band gap changes with heat, rather than recombination mechanisms under ideal operation.
