(1)Excellent cleaning technology
makes the suede surface of the wafer even, so that the sunlight
reflection on the finished solar cells is
reduced.
(2)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.
(3)The unique PECVD coating
technology makes dark blue silicon nitride film with high quality
and even surface.
(4)Good electrical conductivity,
reliable adhesion and excellent weldability.
