Solar Cell, Cell Component, and Photovoltaic System

Abstract

The disclosure provides a solar cell, a cell component, and a photovoltaic system. The solar cell includes a silicon substrate, first doped layers, second doped layers, a first passivation film layer, and first welding spots. The silicon substrate has a first surface and a second surface opposite each other. The first doped layers are arranged on the first surface. The first doped layers each have several first preset zones. The several second doped layers are arranged on the first preset zones, and the second doped layers are arranged in a spaced manner. The first passivation film layer is arranged on the second doped layers and the first doped layers. The first welding spots are arranged on the first passivation film layer. Orthographic projections of the first welding spots on the first doped layers at least partially overlap orthographic projections of the second doped layers on the first doped layers.

Dependencies are inferred from the claim text.
