Definitions
- the present invention relates to a method for manufacturing a solar cell, and more particularly to a method for forming a passivation film formed on a silicon substrate.
- the thickness of silicon substrates is being reduced for the purpose of reducing the amount of silicon used and improving the conversion efficiency of silicon substrates.
- the conversion efficiency decreases significantly. This is because, for example, many defects present on the surface of a conductive silicon substrate are the main factors, and the lifetime of minority carriers (electrons in the case of P-type) generated by light irradiation is reduced. . That is, reducing the disappearance of the minority carriers leads to improving the conversion efficiency of the solar cell.
