Zusammenfassung:Disclosed is a back protection film for photovoltaic module capable of improving the generation performance by adding a retro-reflection unit and improving the reflectance. The back protection film for photovoltaic module comprises: an outer surface layer containing fluorine; an intermediate layer containing PET and stacked on the outer surface layer; and an inner surface layer containing PE, stacked on the intermediate layer, and including the retro-reflection unit increasing the reflectance of light reflected toward a photovoltaic cell. 재귀반사부를 추가하여 반사율을 향상시킴으로써, 발전성능을 향상시킬 수 있는 태양광 모듈용 이면보호필름이 개시된다. 이러한 태양광 모듈용 이면보호필름은 불소를 포함하는 외면층과, PET를 포함하고, 상기 외면층 위에 적층되는 중간층과, PE를 포함하고, 상기 중간층 위에 적층되며, 태양광 셀을 향해 반사되는 빛의 반사율을 높이는 재귀반사부를 포함하는 내면층을 포함하는 것을 특징으로 한다.
