← ScienceWhich risk increases when a photovoltaic cell experiences significant lattice strain?
A)Increased electron-hole recombination rate✓
B)Enhanced quantum tunneling probability
C)Reduced photon absorption cross-section
D)Improved open-circuit voltage output
💡 Explanation
Increased lattice strain introduces structural defects that act as trapping centers promoting electron-hole recombination because these defects disrupt the periodic potential therefore energy is dissipated rather than contributing to current, rather than enhance carrier mobility.
