Which outcome reduces solar cell efficiency due to defects?

💡 Explanation

An increased electron-hole recombination rate lowers photovoltaic conversion efficiencies because Shockley-Read-Hall recombination increases when impurities introduce energy states within a silicon crystal's band gap; therefore electron-hole pairs recombine rather than contribute current.
