The embodiments described below with reference to the accompanying drawings are intended to be illustrative of the invention and are not to be construed as limiting.
如图1所示，本实用新型实施例提供了一种的太阳能电池板，其包括依次贴合的前保护膜100、粘结层200、阻水膜300、前封装胶膜400、薄膜电池芯片500、后封装胶膜600和氧化铝背板700。其中，通过设置氧化铝背板700，增强了该太阳能电池板的防水性，延长了使用寿命，同时，相对于带有玻纤背板的太阳能电池，带有氧化铝背板700的薄膜太阳能电池的重量更大，使用时更有质感，使用者的体验较好。As shown in FIG. 1 , an embodiment of the present invention provides a solar panel including a front protective film 100 , a bonding layer 200 , a water blocking film 300 , a front sealing film 400 , and a thin film battery chip which are sequentially laminated. 500, post-package film 600 and alumina backsheet 700. Among them, by providing the alumina backing plate 700, the waterproofness of the solar panel is enhanced, and the service life is prolonged, and at the same time, the thin film solar cell with the alumina backing plate 700 is compared with the solar cell with the glass backing plate. The weight is greater, the texture is more user-friendly, and the user experience is better.
