<p>A circuit stack structure of a photovoltaic assembly is provided. The structure has a photovoltaic assembly and a frame for the photovoltaic assembly. The photovoltaic assembly has six solar cell strings and bus bars. The left end of a first long bus bar (7) is connected with a first solar cell chip (1) by solder, and the right end of the first long bus bar (7) is connected with a third solar cell chip (3) by solder. The left end of a second long bus bar (8) is connected with a fourth solar cell chip (4) by solder, and the right end of the second long bus bar (8) is connected with a sixth solar cell chip (6) by solder. The left end of a first short bus bar (9) is connected with a second solar cell chip (2) by solder, and the right end thereof is used as an electrode leading end of the photovoltaic assembly. The left end of a second short bus bar (10) is connected with a fifth solar cell chip (5) by solder, and the right end thereof is used as an electrode leading end of the photovoltaic assembly. In the process of laminating the photovoltaic assembly, it is not easy to shift and close to the short bus bar and the solar cell chips for the long bus bar, and it improves yield of the assembly.</p> |
