Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-4, the utility model discloses a solar cell coating tool includes the base plate, and the base plate includes many frames 1, and many frames 1 order end to end makes the base plate form the closed framework of inside fretwork, and in this embodiment, the appearance and the inside fretwork region of base plate all with solar cell phase-match, are square structure.
The film coating jig further comprises a supporting seat 2 used for supporting the solar cell, the supporting seat 2 protrudes from the inner side of the frame 1 into the inner hollowed-out area of the substrate, the width of the frame 1 can be reduced through the supporting of the supporting seat 2 on the solar cell, and therefore the area of the hollowed-out area inside the substrate is increased, namely after the film coating process is operated, the area of the film coating layer coated on the front side or the back side of the solar cell is increased, and the efficiency of the solar cell can be improved.
The supporting seat 2 is at least arranged on one frame 1, and preferably, the supporting seat 2 is arranged on each frame 1. In this way, the width of each frame 1 of the substrate can be properly reduced compared with the prior art, so that the coverage area of each edge coating layer on the front surface or the back surface of the solar cell is increased.
The cross section of the supporting seat 2 can be one or more of square, round, triangular, semicircular and irregular, wherein the irregular shape refers to a figure with an irregular cross section shape. Of course, the cross section of the support base 2 can also take other forms.
