Embodiment 1

[0032] Such as Image 6 As shown, a high-efficiency solar cell that is convenient for testing provided in this embodiment is a multi-busbar battery, including: a cell body 1, 12 busbar lines 2 are arranged on the front of the cell body 1, and several thin For the gate lines, eight pads 3 are arranged at equal intervals along the length direction of each main gate line 2 .

Embodiment 2

[0034] Such as Figure 7 As shown, a high-efficiency solar cell that is convenient for testing provided in this embodiment is a busbar-free cell, including: a cell body 1, and several thin grid lines are arranged on the front of the cell body, and the thin grid lines include Several horizontal thin grid lines and four vertical thin grid lines 4 have no main grid, and eight pads 3 are arranged at equal intervals along the length direction of each vertical thin grid line 4 .

Embodiment 3

[0036] Such as Figure 8 As shown, this embodiment provides a test device for high-efficiency solar cells, which is used to test the multi-busbar battery provided in Embodiment 1. It has several probe rows 5, and several probes 6 are arranged on the probe rows. It is made of transparent material, and the number of probe rows is consistent with the number of busbars of the multi-busbar solar cell provided in embodiment 1, which is 12 probe rows; each probe row is on the corresponding solar cell pad 3 Drill a hole at the position, install the probe 6, the diameter of the probe 6 is 2.0-3mm, and the spring pressure on the top of the probe is 1.2-2N.

[0037] Specifically, the material of the probe row is transparent PMMA, the diameter of the probe is 2.5mm, and the spring pressure on the top of the probe is 1.5N.

Abstract

The invention discloses an efficient solar cell convenient to test. The efficient solar cell comprises a cell body. A plurality of main grid lines are arranged on the front surface of the cell body. The efficient solar cell is characterized in that a plurality of bonding pads are equidistantly arranged along the length direction of each main grid line. The invention further discloses a device for testing the efficient solar cell. The device is used for testing the efficient solar cell shown in claims 1-2 and is provided with a plurality of probe rows. A plurality of probes are arranged on the probe rows. The probe rows are made of transparent materials, the quantity of the probe rows is consistent with the quantity of the main grid lines of the efficient solar cell, the locations, which correspond to the bonding pads of the efficient solar cell, on each probe row are perforated, the probes are mounted, the diameters of the probes are 2.0-3.0 mm, and spring pressures of the tops of the probes are 1.2-2 N. The efficient solar cell and the device have the advantages that accurate test results can be obtained, the device is long in service life, and the like.

Description

technical field [0001] The invention relates to a high-efficiency solar battery and a testing device thereof which are convenient for testing, and belong to the technical field of solar battery testing. Background technique [0002] With the continuous development of technology and changes in market demand, the design styles of positive electrodes of crystalline silicon solar cells are increasing, and multi-busbar cells, busbar-connected-gate cells, and busbar-free cells have appeared. new challenges. [0003] No busbar battery, such as figure 1 As shown, generally considering the influence of bad welding, broken grid, etc., the position of the welding strip is designed as a thin grid to ensure that the welding strip can effectively collect current when the welding is poor; [0004] And the multi-busbar battery, such as figure 2 As shown, a thinner main grid is used and welded together with a thin ribbon. [0005] In the prior art, the methods for testing these batterie...
