Publication number: 20240355942Abstract: The present disclosure provides a texture structure of a solar cell and a preparation method therefor. The texture structure includes a texture with a surface including a contact region and a non-contact region. The contact region is provided with a metal gate line, and has a specific surface area smaller than the non-contact region. According to the texture structure of a solar cell and the preparation method therefor provided by the present disclosure, the texture of a metal gate line coverage region and the texture of a metal gate line non-coverage region form different microscopic appearances of texture structure, and the texture structure in the non-coverage region has a specific surface area much larger than the texture structure in the coverage region, thereby reducing a contact area between a slurry metal and a PN junction on the texture, reducing the metal recombination by more than 20%, and improving the conversion efficiency.Type: ApplicationFiled: September 23, 2022Publication date: October 24, 2024Inventors: Hong CHEN, Jifan GAO, Yifeng CHEN
