Solar cell backsheets play an important role in solar panels. It is not only able to provide support and protection for the solar panels, but also to affect the performance of the solar panels. The solar cell backsheet can protect the solar panel from the external environment, such as wind and rain, ultraviolet rays and other natural factors, so as to prolong the service life of the solar panel. Therefore, it is very important to test the moisture permeability of the solar cell backsheet.
The solar cell backsheet water vapor permeability tester is a commonly used equipment to test the moisture permeability performance of the solar cell backsheet.
Test principle of solar cell backsheet water vapor transmittance tester:
The instrument adopts the infrared sensor method test principle, the sample to be tested is sandwiched between the dry and wet chambers at constant temperature, there is a certain humidity difference on both sides of the sample, due to the existence of humidity gradient, water vapor will diffuse from the high humidity cavity to the low humidity cavity, in the low humidity cavity, the water vapor is carried to the infrared sensor by the carrier gas, and the same proportion of electrical signals will be generated when entering the sensor, and the water vapor transmission rate and moisture permeability coefficient of the sample are obtained through the analysis and calculation of the electrical signal of the sensor.
Solar Cell Backsheet Water Vapor Transmission Rate Tester Components:
The solar cell backsheet water vapor transmittance tester is mainly composed of four parts: infrared sensor, test cavity, high-definition LCD touch screen, and data processing and detection system. High-precision infrared moisture sensor, which improves the accuracy and stability of the test. The four test chambers are completely independent and can test up to four identical or different specimens at the same time. High-definition LCD touch screen, the content is more intuitive, and the operation is more convenient. The test results can be stored in multiple formats and data output, including Excel and cloud sharing.
Application Importance of Solar Cell Backsheet Water Vapor Transmittance Tester:
1.Extend the life of your solar panels. By using this equipment, the moisture permeability of the solar cell backsheet can be effectively detected, and the solar panel can be better protected from external forces and the service life can be prolonged.
2.Ensure the stable performance of the solar panels. By testing its moisture permeability, it can be more accurate to ensure the stable performance of solar panels.
3.Optimize the production and processing technology of products. By using the secondary instrument, the water vapor transmission rate data of the solar cell backsheet can be obtained, which can be used as a reference for manufacturers. Based on the test results, manufacturers can optimize product design and process flow to improve the performance and quality of solar cell backsheets.
The solar cell backsheet water vapor transmittance tester is an important testing equipment for evaluating the solar cell backsheet, which can better ensure the product quality of the solar cell backsheet and improve the service life of the solar panel.
