← ScienceWhich process limits efficiency when crystalline silicon solar cells heat?
A)Increased electron-hole recombination✓
B)Decreased photon absorption rate
C)Enhanced surface plasmon resonance
D)Suppressed piezoelectric effect
💡 Explanation
Elevated temperatures cause more energetic electrons, therefore electron-hole recombination increases due to increased thermal agitation within the crystal lattice. This band-to-band Auger recombination prevails rather than amplified absorption or plasmon effects.
