Projects
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.
