Abstract

The invention discloses a solar cell and a manufacturing method thereof, relates to the technical field of photovoltaics, and aims to reduce damage to a doped surface. The manufacturing method of the solar cell comprises the following steps: providing a silicon substrate; forming a protective film on the silicon substrate; forming a doped source layer on the protective film, wherein the doped source layer is a doped source film formed by a dopant solution or a dopant slurry; and pushing doping elements in the doping source layer into the silicon substrate through the protective film in a heat treatment mode so as to dope the silicon substrate. The solar cell and the manufacturing method thereof provided by the invention are used for manufacturing the solar cell.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a solar cell and a manufacturing method thereof. Background technique [0002] The process of making solar cells mainly includes: texturing, doping, cleaning, depositing anti-reflection film, testing, sorting, etc. Wherein, the doping process may be to form a doping source on the surface of the silicon substrate, and then perform annealing. [0003] When the doping process is carried out by means of doping source coating advancement, the doped surface is easily damaged, thereby affecting the performance of the solar cell. Contents of the invention [0004] The purpose of the present invention is to provide a solar cell and its manufacturing method, so as to reduce the damage of the doped surface. [0005] In a first aspect, the present invention provides a method for manufacturing a solar cell. The manufacturing method of the solar cell comprises: [0006] providing a...
