【Product description】
With the growth of diamond wire sawing, black silicon’s popularity has soared quickly and it has brought about a resurgence in multicrystalline silicon with the benefits of cost effective and high efficiency for PV industry.
Black silicon deals with front side texturing and has no conflicts with other processes like diffusion, passivation, or metallization,moreover, black silicon can be combined with PERC technology, which makes multi-PERC much more competitive compared with mono-PERC.
Industrialized poly black silicon with the PERC process, an average conversion efficiency of 20.5% had been achieved and the corresponding solar module can attain 290W.
