Amorphous Silicon Solar Panel Production Processing

Let go to the factory and see the production processing .
It’s about 13step:
1 make SnO2 condutive glass . (as we know glass don’t conduct electricity , when we want to change it’s performance , we should add a thin film , TCO (transparent conduction oxide ) so that it can transmit electricity ,and visible light can pass through .
Now we don’t have these machine , so we import the TCO glass from German and Japan .next year , we will start to produce the TCO glass in our factory .
2. Use Red laser-light cut SnO2
Now one glass is one solar cell ,we use red laser-light to cut it into 36 solar cells .
The light diameter is less than 100um
And speed is faster than 500 meter per second .
3. after this step , there are some dust, we use special machine to crean them .
4.to mount the creaning glass to “deposition jip” ,push the jip to preherter furnace.
5. after that ,move to PECVD furnace ,make the chemical vapor deposition .(p-i-n)
6. cool the glass naturally .
7. use the green laser light to cut “pin” film into small cells .
8. plate the aluminium at the back , to form back elecctrode .
9. I-V testing .
10. aging testing
11. use UV （Ultraviolet Rays） glue to protect
12. Encapsulation:Laminator ,Aluminium frame with junction box assemble cable with battery clamps.
13. finish testing and packing
