Method for manufacturing solar cell

A method for manufacturing a solar cell, comprising:

• providing a wafer, wherein:
• the wafer includes a substrate and a doped conducting layer;
• the substrate includes a first surface, a second surface, and first side surfaces, the first and second surfaces are opposite to each other, the first side surfaces are adjacent to and between the first surface and the second surface;
• at least the first surface and a portion of at least one of the first side surfaces of the substrate comprise a textured structure;
• the doped conducting layer is disposed at least on the first surface and the portion of the at least one of the first side surfaces, thereby covering the textured structure,
• forming a passivating contact layer on the second surface of the substrate,
• forming a first passivation layer on the doped conducting layer, wherein the first passivation layer covers the first surface and at least the portion of the at least one of the first side surfaces, thereby covering at least the doped conducting layer, and
• forming a second passivation layer on the passivating contact layer, thereby forming a solar cell matrix, wherein the second passivation layer covers the second surface, thereby covering the passivating contact layer.
