Solar cell

The utility model relates to a solar cell, which comprises front plate glass, a first adhesive film, a cell piece assembly, a second adhesive film and rear plate glass which are sequentially arranged, a silicon dioxide layer is arranged on the surface of one side, close to the first adhesive film, of the front plate glass, and the cell piece assembly is used for conducting electricity and absorbing light. According to the utility model, Na < + > ions in the front plate glass can be prevented from migrating into the solar cell, and the light transmittance of the material can be prevented from being reduced. 本实用新型涉及一种太阳能电池，包括依次设置的前板玻璃、第一胶膜、电池片组件、第二胶膜以及后板玻璃，在前板玻璃靠近第一胶膜的一侧的表面设置有二氧化硅层，电池片组件用于导电以及吸光。本实用新型能够阻止前板玻璃中的Na+离子向太阳能电池内部迁移，且能够避免降低材料的透光度。
