A solar cell protective material having two or more anti-moisture films having a steam penetration ratio less than 0.1 g/(m2·day) and having a metal oxide layer on at least one surface of the base material, wherein the anti-moisture films are layered with an adhesive layer interposed therebetween, the adhesive layer comprising a polyurethane adhesive in which a polyurethane polyol having a viscosity of 200-1000 mPA·s at 25°C is used. La présente invention se rapporte à un matériau de protection de cellule solaire qui présente au moins deux films anti-humidité qui présentent un taux de pénétration de vapeur inférieur à 0,1 g/(m2·jour) et qui présentent une couche d'oxyde métallique sur au moins une surface du matériau de base, les films anti-humidité étant disposés en couches, une couche adhésive étant intercalée entre ces derniers, la couche adhésive comprenant un adhésif en polyuréthane dans lequel est utilisé un polyol de polyuréthane qui présente une viscosité comprise entre 200 et 1 000 mPA·s à une température de 25 °C.
