← ScienceWhich consequence results when exceeding the design limits of amorphous silicon in solar panel manufacturing?
A)Increased electron-hole recombination rate✓
B)Formation of crystalline grain boundaries
C)Elevated open-circuit voltage levels
D)Decreased short-circuit current losses
💡 Explanation
Amorphous silicon has defects creating band tail states; exceeding deposition temperature increases defect density, which causes increased electron-hole recombination via trap states rather than enhanced structural order. Therefore, open-circuit voltage decreases because carrier lifetime degrades significantly.
