Typical electrical characteristics

Data under standard testing conditions(stc):1,000w/m2, am1.5, 25ºc, pmax:Positive power tolerance.

The quality of all cells is 100% safety guarantee because they are protectively warehoused.
Any quality problem (defective products) could be return, except that broken solar cell are required by customers.
All cells are tested before delivery as customers required.

Solar Cell Production Line
156.75*156.75mm 4bb Poly Solar Cell 18.6

Cleaning & Texturing: Wafers are cleaned with industrial soaps and form square-based pyramids also called texture. The texturization helps to reduce the reflection of sunlight. 

Diffusion: Wafers that have been pre-droped with boron during the casting process are then given a negative(n-type) surface characteristic by diffusing them with a phosphorus source at high temperature, which in turn creats the negative/positive(n-p) junction.

Etching: Phosphorus diffuses not only into the desired wafer surface but also into the side and the opposite surface to form PN. This gives a shunt path between the cell front and rear. Removal of the path around the wafer edge/edge junction isolation is named etching.

PECVD: By PECVD equipment, the wafers are coated with anti-reflection coating(ARC). It's the blue silicion nitride film to reduce reflection and promote absorption of light.

Printing & Heating: it was adopted by printing paste with screen technology to print the electrodes of silicion solar, and form a good ohmic contact.
Testing & Sorting: It means classifying the cells according to their efficiency tested under the simulated sunlight.
