← ScienceWhich outcome results when imperfections cause thin-film interference in silicon photovoltaic cells?
A)Reduced energy conversion efficiency✓
B)Increased electron-hole recombination
C)Enhanced short-circuit current
D)Improved open-circuit voltage
💡 Explanation
Reduced energy conversion efficiency occurs because *destructive interference* reduces transmitted light through the active silicon layer, therefore less light absorbed and fewer electron-hole pairs created, rather than an enhanced current which would imply constructive interference.
