| Zusammenfassung: | This invention discloses a surface structure of crystalline silicon solar cell and its manufacturing method. The surface structure includes a main body, where the main body includes a front-side microstructure and a back-side microstructure. The roughness coefficient of the front-side microstructure is greater than that of back-side microstructure. The surface configuration of the front-side microstructure includes a plurality of cone-shaped bodies, and the surface configuration of the back-side microstructure includes a plurality of polyhedrons. |
