Zusammenfassung:A solar cell (1) includes a semiconductor substrate (11), a bus-bar electrode (12), a plurality of finger electrodes (13), and a heavily doped layer (14). The semiconductor substrate (11) has a surface (111). The bus-bar electrode (12) is on the surface (111) of the semiconductor substrate (11) and extending along a first direction. The finger electrodes (13) are on the surface (111) of the semiconductor substrate (11) and extending along a second direction. One of two ends of each of the finger electrodes (13) is connected to the bus-bar electrode (12). An angle created by the first direction and the second direction is less than 180 degrees. The heavily doped layer (14) is formed on the surface (111) of the semiconductor substrate (11) and includes a first portion (141) and a plurality of second portions (142). The first portion (141) is extending along the first direction. Each of the second portions (142) is extending from the first portion (141) along the second direction and beneath the corresponding finger electrode (13).
