  • Publication number: 20230327036
    Abstract: A solar cell structure includes a semiconductor substrate having a front side and a back side. A pyramid structure is disposed on the front side of the semiconductor substrate. The pyramid structure has an aspect ratio between 0.5-1.2. A front passivation layer is disposed on the pyramid structure. A first anti-reflection layer is disposed on the pyramid structure. The first anti-reflection layer is a multi-layered, graded anti-reflection layer having at least three coating layers. The at least three coating layers comprise a silicon oxynitride layer having a thickness of 15-30 nm and a refractive index between 1.65 and 1.75. The silicon oxynitride layer is an outermost layer of the multi-layered, graded anti-reflection layer.
