The present application relates to an encapsulant for a PV module, a method of manufacturing the same and a PV module. The encapsulant according to an embodiment of the present application has excellent heat resistance or the like and improved creep physical properties, and thus even when the encapsulant is used under conditions of a high temperature and/or high humidity for a long time, deformation is small and the encapsulant can exhibit excellent adhesive strength. Accordingly, when the encapsulant is applied to a PV module, durability or the like may be improved.

A hot melt adhesive film, and a preparation method, use, and an organosilicon polymer thereof are provided. The hot melt adhesive film includes: an inner layer, which is a polyolefin elastomer (POE); outer layers, which are an ethylene-vinyl acetate (EVA) copolymer on two surfaces of the inner layer; and intermediate layers, which are an organosilicon polymer between the inner layer and the outer layers. As intermediate layers, the organosilicon polymer plays the role of connection and transition, improves a bonding force between EVA and POE layers, and improves the stability of the hot melt adhesive film during long-term use. The hot melt adhesive film can be used as a packaging material for solar panels, touch screens, and the like.

Disclosed are a sealing material for solar cell modules and a manufacturing method thereof capable of endowing good transparency and heat resistance to the sealing material for solar cell modules while using a polyethylene-based resin.
