Abstract
The present application provides a silicon-based heterojunction solar cell and a manufacturing method thereof. The silicon-based heterojunction solar cell includes: a silicon substrate, as well as a first passivation layer, an N-type doped layer, a first transparent conductive oxide layer and a first electrode. The first passivation layer, the N-type doped layer, the first transparent conductive oxide layer and the first electrode are sequentially stacked on the front side of the silicon substrate along a first direction. The first passivation layer includes a first sub-passivation layer, a carbon-doped amorphous silicon layer and a second sub-passivation layer which are sequentially stacked along the first direction.
