Embodiment 1

[0038] A kind of snail pattern test device of solar cell module, such as figure 1 As shown, it includes a high-voltage accelerated aging test test box 1, wherein the test device also includes a test piece support 2 placed in the test box 1 for carrying multiple test pieces, such as figure 2 As shown, it includes a hollow cuboid support body 21 with a front opening and at least one partition 22 arranged horizontally inside the support body 21 .

[0039] Further, four partitions 22 are provided.

[0040] Further, the bracket 2 is made of stainless steel.

[0041] Further, the bracket 2 can withstand a temperature of -100°C to 200°C.

[0042] Further, the support 2 can withstand 0-100% RH humidity.

[0043] Further, the support 2 can withstand 1-3 atmospheres.

[0044] After the support 2 is placed in the experiment box 1, the experiment box can only place one piece of test piece at a time, but now it can hold multiple test pieces, which greatly improves the experiment effic...

Embodiment 2

[0062] Only the differences from Embodiment 1 will be described below.

[0063] Select 80 normal cells with no cracks, tap all the cells with a pencil until the cells are obviously cracked, and make 10 cracked laminates. The laminates made of 10 cracked batteries were selected from the test conditions and observation period of the present invention (temperature: 120°C; humidity: 100% RH; air pressure: 2 atmospheres; cycle: 24h), and 10 normal comparison laminates were selected from other inventions Test conditions and test cycle (temperature: 85°C; humidity: 85% RH; light intensity: 1000W / M2; cycle: 1000h). Specifically as shown in Table 2:

Abstract

The invention belongs to the technical field of snail grain testing and relates to a solar battery module snail grain testing device and method. The device comprises a high-pressure ageing accelerating testing experimental box and a test piece rack arranged inside the experimental box for bearing test pieces, wherein the test piece rack comprises a cuboid-shaped rack body with a hollow front opening, and at least partition boards horizontally arranged inside the rack body. The method comprises 1, manufacturing a snail grain battery, 2, manufacturing a laminating member, 3, sealing the laminating member, 4, testing the laminating member, and 5, observing snail grains. The solar battery module snail grain testing device and method has the advantages of, 1, greatly shortening the testing period, 2, avoiding the problem of unqualified solar modules due to the snail grains, and 3, being safe, reliable, accurate in evaluation, reasonable in testing period and applicable to being widely applied to predictive testing of snail grains of solar battery modules.

Description

technical field [0001] The invention belongs to the technical field of snail pattern testing, and relates to a snail pattern testing device and a testing method of a solar cell module. Background technique [0002] The so-called snail pattern refers to the discoloration of irregular fine grids that appear on the surface of the battery during the use of the module. It looks like a "snail pattern" from the appearance. It was first proposed in 2004 by the German Institute for Solar Energy Research in Hameln (ISFH ) Research project leader Marc Kontges found that the possible conditions for its occurrence may be related to comprehensive outdoor factors such as component materials, light, temperature, and humidity. A must for a snail pattern. At present, there is no special test item for snail pattern in the industry, and there is no test method for snail pattern. In the certification process of IEC61215:2005, IEC21730:2004, and UL1703:2004 international standards, there is no ...
