← ScienceWhich outcome occurs when amorphous silicon in solar panel is heated above glass transition temperature?
A)Increased electron-hole recombination rate
B)Crystallization reduces light absorption✓
C)Enhanced conversion efficiency short term
D)Reduced band gap improves conductivity
💡 Explanation
When amorphous silicon exceeds its glass transition temperature, crystallization occurs because atoms gain mobility and form ordered lattices, leading to reduced light absorption by the previously disordered amorphous structure. Therefore crystallization limits sunlight absorption rather than enhancing conversion efficiency, conductivity, or recombination because these require different changes.
