<p>A circuit stack structure for 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 the first long bus bar (7) is connected with the 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 second long bus bar (8) is connected with the 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 a leading end of an electrode 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, the right end thereof is used as a leading end of an electrode of the photovoltaic assembly, in the process of laminating the photovoltaic assembly, the long bus bar is not easy to be shifted, and it is not easy to get close to the short bus bar and solar cell chips, which improves yield of the photovoltaic assembly.</p> |
