What consequence do you expect in a p-n junction solar cell when the device temperature is increased and the direct electron excitation over the band gap becomes significant? Chose one from the following: (i) The efficiency is enhanced by the direct thermal excitation of electrons. (ii) The efficiency of the device is unaffected by the direct thermal excitation of electrons. (iii) The device fails to work as a solar cell because of the direct thermal excitation of electrons.
