The invention provides a perovskite solar cell. The perovskite solar cell sequentially comprises an upper packaging layer, an upper light-transmitting electrode layer, an upper carrier transmission layer, a light absorption layer, a lower carrier transmission layer, a lower light-transmitting electrode layer, a filling material layer, packaging glue and a lower packaging layer, wherein the surface of the filling material layer, which is not in contact with the lower light-transmitting electrode layer, is coated by the packaging adhesive, or the filling material layer and the packaging adhesive are different layers; wherein the chromaticity difference (formulated by International Committee for Lighting) between the color of the filling material layer and the material of the light absorbing layer is less than 2, and the light transmittance difference is less than 10%. 本发明提供一种钙钛矿太阳能电池，依序包含：一上封装层、一上透光电极层、一上载流子传输层、一吸光层、一下载流子传输层、一下透光电极层、一填充材料层、一封装胶以及一下封装层；其中该填充材料层未接触该下透光电极层的表面被该封装胶包覆或者该填充材料层与该封装胶为不同层；其中该填充材料层的颜色与该吸
