Imodyuli ye-solar monocrystalline silicon emacala amabini e-PERC yimodyuli yelanga eyenziwe ngezinto ze-silicon ze-monocrystalline, enekhono lokuguqulwa kwe-photoelectric kabini.I-PERC sisishunqulelo se "i-back side ye-Verick effect", eyona iteknoloji yeeseli ezicacileyo zangasemva, ezinokuphucula ukuphuma kwamandla kwiimodyuli zeeseli zelanga.
