Abstract
The application provides a solar cell, a manufacturing method, a photovoltaic device and a photovoltaic system. The solar cell includes a substrate, a doped conducting layer, a first passivation layer, an anti-reflection layer, a passivation contact layer, and a second passivation layer. The substrate includes opposite first and second surfaces, and side surfaces between the first and second surfaces. The doped conducting layer and the first passivation layer are sequentially stacked on the first surface. The anti-reflection layer is stacked on the first passivation layer and covers the first surface to cover the first passivation layer. The passivation contact layer is stacked on the second surface. The second passivation layer is stacked on the passivation contact layer and covers the second surface to cover the passivation contact layer. The anti-reflection layer or the second passivation layer covers at least part of at least one side surface of the substrate.
