Manufacturing method of heterojunction solar cell

The invention relates to a manufacturing method of a heterojunction solar cell, which comprises the following steps of: performing texturing on a second main surface of a semiconductor substrate, and then performing semi-polishing operation on the second main surface of the semiconductor substrate to remove partial textured surface on the second main surface. The invention aims to provide the manufacturing method of the heterojunction solar cell, and the prepared solar cell is higher in conversion efficiency and lower in production cost. 本发明涉及一种异质结太阳能电池的制作方法，在半导体基板的第二主面进行制绒后，对半导体基板的第二主面进行半抛光操作，除去第二主面上的部分绒面。本发明的目的在于提供一种异质结太阳能电池的制作方法，其制备的太阳能电池转换效率更高，且生产成本更低。
