					Henergysolar improved process of laminating machines instead of autoclave forming. So our patent can save lots of money and make the BIPV solar module cost down.

					As we all know, cracked may induce wafer broken and impact cell efficiency. How to detect micro crack is one critical problem, henergysolar provide advanced tool to detect them conveniently.

					The antireflective is very important process. Uneven film impact the number of incoming photons, thus determining the efficiency of the cell power.

					Uneven diffusion impact the litetime of minority carrier, and ultimate impact the efficiency of solar cells.
