1 Vacuum Coating (Vacuum Coater): Spray method (Sputter) is used to spray Mo onto the substrate; then a CIG precursor film (precursor
2 Selenization reactor (selenization reactor): Se vapor; reacts with the precursor to form a light-absorbing CIGS layer in a high temperature vacuum environment; < /p>
3 Chemical deposition (CBD), depositing CdS buffer film by CBD method; >4 Transparent oxide film (TCO), the equipment is basically the same as vacuum coating equipment in 1, using vacuum spray method for ZnO:Al coating;
We call the above the front end (front end), so far, the battery structure is basically completed, but the finished product still needs further processing The general process is as follows:
1. Cut the battery roll to the required width.s (grid);
3 Lamination: Laminate the protective film and the battery using a laminator;
4 Install the positive and negative wire connector;
After that, it is time to install the outer frame and others according to the needs of the product. Of course, there are also a series of testing equipment and steps to test efficiency, open loop voltage, service life, etc. drums.
