Abrégé
Embodiments of the present disclosure provide a heterojunction solar cell and a preparation method therefor. The heterojunction solar cell comprises: a silicon substrate, wherein at least one of the front and back surfaces of the silicon substrate is a textured surface of a pyramid structure; silicon-based films provided on the front and back surfaces of the silicon substrate, wherein each silicon-based film comprises an intrinsic layer and a doped layer provided on the side of the intrinsic layer facing away from the silicon substrate, the doping types of the doped layers provided on the front and back surfaces of the silicon substrate are opposite, and the thickness of the silicon-based film covering the pyramid structure decreases as the silicon-based film covering the pyramid structure gets closer the silicon substrate; and a transparent conductive layer and grid electrodes provided on the side of each silicon-based film facing away from the silicon substrate. The apex of the pyramid structure is a stress concentration point, and the stress gradually decreases in a downward direction. In the coating process of the transparent conductive layer, because the silicon-based film at the apex is thick, the transparent conductive material in an apex area can be prevented from being bombarded into an interface of the silicon substrate, thereby preventing interface recombination and improving the efficiency of heterojunction solar cells.
