The utility model discloses a high-weatherability coating type solar cell backboard film comprising a backboard film main body, a PVDF coating, a thin steel layer, a graphite layer, a rubber layer, aPET layer, a glass fiber reinforced plastic layer and an EVA layer. Due to the design of the PVDF coating, the environmental erosion resistance of the backboard film main body is improved; due to thedesign of the thin steel layer, the waterproof effect of the backboard film main body is improved; the design of the graphite layer improves the heat dissipation effect of the backboard film main body, the design of the rubber layer improves the shockproof buffer effect of the backboard film main body, the design of the PET layer improves the insulation effect of the backboard film main body, thedesign of the glass fiber reinforced plastic layer improves the anti-corrosion effect of the backboard film main body, and the design of the EVA layer facilitates the adhesion of the backboard film main body. 本实用新型公开了一种高耐候性涂覆型太
