← ScienceWhich consequence results from reduced crystalline order in solar cells?
A)Decreased open-circuit voltage appears✓
B)Increased short-circuit current emerges
C)Higher charge carrier mobility occurs
D)Lower series resistance becomes observable
💡 Explanation
Decreased crystalline order increases electron-hole recombination because trap states, caused by defects, introduce energy levels within the band gap serving as recombination centers. Therefore, the open-circuit voltage decreases, rather than increasing efficiency through other electrical effects.
