Abstract
The present application relates a solar cell, a photovoltaic device and a photovoltaic system. The solar cell includes a substrate, a first passivation layer, and a second passivation layer. The substrate includes a first surface and a second surface opposite to each other along a thickness direction of the substrate. The first passivation layer is disposed on the first surface of the substrate. The second passivation layer is disposed on a side of the first passivation layer away from the substrate. A material of the first passivation layer is the same as that of the second passivation layer. An atomic packing density of the first passivation layer is higher than that of the second passivation layer. An average thickness of the first passivation layer is smaller than that of the second passivation layer.
