Perovskite solar cell

The utility model provides a perovskite solar cell. The perovskite solar cell comprises a substrate layer, a first carrier transport layer, a perovskite light absorption layer, a second carrier transport layer, a back electrode layer, a back electrode protection layer, an adhesive film layer and a packaging glass layer which are stacked in sequence. And the thickness of the back electrode protection layer is 0.01 to 0.15 mm. The perovskite solar cell provided by the utility model not only can prevent the phenomenon that the internal stress of the assembly is generated due to the melting of the adhesive film and acts on the surface of the electrode to cause the demolding, but also can isolate the water and oxygen components in the environment, thereby effectively improving the stability and service life of the cell. 本实用新型提供一种钙钛矿太阳能电池。所述钙钛矿太阳能电池包括依次层叠的衬底层、第一载流子传输层、钙钛矿吸光层、第二载流子传输层、背电极层、背电极保护层、胶膜层和封装玻璃层；所述背电极保护层的厚度为0.01～0.15mm。本实用新型提供的钙钛矿太阳能电池不仅能够防止因胶膜熔融而产生组件内应力作用于电极表面从而发生脱膜的现象，还能够隔绝环境中的水氧组分，进而有效提高电池的稳定性和使用寿命。
