Backsheet TPT Film Tester for Solar Panel of Solar Cells

Backsheet TPT Film tester
for Solar Panel of
Solar Cells
Backsheet TPT Film tester of Water Vapor Transmission Rate Test system developed by Labthink has ultra high resolution and accuracy, it can be used to test the water vapor transmission rate of the backsheet film.

And the XLW series Auto Tensile Testers can be used to perform the bonding force tests of laminated layer, as well as other items like elongation, distortion and etc.

The quality control of backsheet film for solar panel of solar cell plays the most important role on the quality control of solar cells. The backsheet can protect the photovoltaic components, like solar panel. The main quality of the backsheet is determined by its water vapor barrier property. If the backsheet can not block the water vapor in the air, the vapor will enter and break the bonding force between EVA layer and the panel. When the water vapor contact with solar panel directly, the solar panel will be oxidated and lose its function of generating current.

Currently, international community pays more and more attention to the environmental conservation and energy saving industries. This means the solar cells industry is growing, and maybe one day it will be the main energy industry in the world. This is why we should talk about the quality control of the components of solar cells, especially the backsheet film.
