Which mechanism causes decreased efficiency in solar cells facing heat?

💡 Explanation

Elevated temperatures cause increased electron vibrational energy thereby exceeding the band gap, increasing the electron-hole recombination rate. Increased electron-hole recombination reduces cell voltage, because fewer charge carriers reach the electrodes therefore decreasing efficiency, rather than leading to trapping.
