Abstract

In a solar cell, first and second doped portions are alternatingly arranged along a first direction, disposed on a first surface of a substrate, and have different conductivity types. Each first doped portion includes first and second portions alternatingly arranged along a second direction, and a dopant concentration of the second portions is greater than that of the first portions. A passivation layer is disposed on the first surface. Fingers are disposed on the first surface, extend through the passivation layer, and include multiple rows of first fingers and multiple rows of second fingers that are alternatingly arranged along the first direction. First fingers in a same row are arranged at intervals in the second direction, and second fingers in a same row are arranged at intervals in the second direction. At least a portion of the first fingers is disposed on a corresponding ones of the first portions, and two adjacent first fingers in the second direction are connected to each other via a corresponding one of the second portions. At least a portion of the second fingers is disposed on a corresponding ones of the third portions. First and second busbars are alternatingly arranged in the second direction, extend along the first direction, and are disposed on the passivation layer. At least a portion of each second busbar is disposed over a column of second portions arranged along the first direction, the first and second busbars are connected to the first and second fingers, respectively.
