摘要： A lead trapping layer includes an acidic cation-exchange resin comprising a formula selected from the group consisting of Formulae (I) to (V) below, in which each M+is independently selected from the group consisting of Sr2+, Ca2+, Ni2+, Cu2+, Co2+, Zn2+, Mg2+, Ba2+, K+, NH4+, Na+, H+, and Li+; and each R is independently selected from the group consisting of SO3H, CH2SO3H, PO3H2, and COOH; and an encapsulation resin selected from the group consisting of epoxy resin, silicone resin, arcrylate resin, and a combination thereof. A solar cell device includes at least one lead trapping layer and a method may prepare the lead trapping layer.
