Processing Steps Of Thin-film Solar Cell

1) SUBSTRATE PREPARATION

TCO coated glass -> Glass edge trimmer

2) SUBSTRATE CLEANING

TCO coated glass -> Glass washer

3) CUTTING WITH LASER

TCO coated glass -> Laser Scriber (1st) -> TCO-coated glass after cutting

4) SUBSTRATE CLEANING AFTER LASER CUTTING

TCO coated glass -> Glass washer

5) PUTTING 48 PCS OF SUBSTRATES INTO THE BOX CARRIER

Gas box - Gas substrate - power ladder - box carrier

6) 

Box carrier -> Preheat Oven

7) DEPOSITION OF THIN-FILM SI

PECVD system for a: Si/uc-Si deposition

8) Substrates

Box carrier -> Cool down oven

9) Output the substrates

Box carrier -> Glass substrate coated with thin-film Si -> Gas box

10)  CUTTING OF THIN-FILM SI

Laser scriber (2nd green)

11) BACK ELECTRODE

Cell -> sputtering system for ZnO/Al, Ag deposition -> cell -> Laser scriber (3rd green) -> cell with thin-film

12) TESTING THE MODULE PERFORMANCE

Solar simulator

13) LAMINATION

Trays with modules EVA and backing plates -> Laminator
