← ScienceWhich outcome occurs when temperature raises in photovoltaic crystal?
A)Carrier mobility decreases, efficiency decreases.✓
B)Ferromagnetic domains align; magnetism strengthens.
C)Photon wavelength decreases; energy absorption lowers.
D)Crystal lattice stabilizes; defect formation halts.
💡 Explanation
Carrier mobility decreases because rising temperatures increase phonon scattering, thereby impeding electron movement. This reduces photovoltaic efficiency because fewer charge carriers reach the contacts; therefore, efficiency lowers rather than increases that can increase through charge carrier increases.
