This disclosure relates to a solar cell module comprising: (i) a solar cell layer, and (ii) a front sheet composed of a transparent substrate and an antifouling layer being located on the front side of the transparent substrate, wherein the antifouling layer comprises a perfluoropolyether silane of Formula (1), wherein Rf is R3O(CF(CF3)CF2O)pCF(CF3)-, R3O(CF2CF2CF2O)qCF2CF2-, or R3O(CF2CF2O)rCF2-; R1, R2, R3, m, n, x, p, q, and r are defined in the disclosure. Said antifouling layer not only improves the power conversion efficiency by reducing the accumulation of dust particles, but also prolongs the utility life of the solar cell module due to excellent UV stability. |
