Which mechanism causes substantial efficiency loss in polycrystalline silicon solar cells?

💡 Explanation

Efficiency drops because grain boundaries introduce defects that trigger Shockley-Read-Hall recombination, therefore charges recombine non-radiatively rather than contributing to current, because gap states act as trapping centers at these defects.
