Which risk increases when a photovoltaic cell's temperature rises, reducing its band gap?

💡 Explanation

Increased temperature enhances electron-hole recombination because reduced band gaps provide more available energy states for electrons to lose energy non-radiatively via thermalization processes and traps. Therefore, charge carrier lifetime decreases rather than increasing voltage or carrier generation.
