Characteristics:
Excellent cleaning technology makes the suede surface of the wafer even, so that the sunlight reflection on the finished solar cells is reduced.
Diffusion technique of low concentration and shallow junction optimizes the quality of junction region, , reduces dead layers and ensures the uniformity of diffusion square resistance.
The unique PECVD coating technology makes dark blue silicon nitride film with high quality and even surface.
Good electrical conductivity, reliable adhesion and excellent weldability.
Low fragmentation rate and high quality rate.
Extremely low power loss in components.
