					As we know, the most serious problem is cutting lines cut off during silicon block process! Inappropriate process and improper operation will cut off, but the main cause is that hard particles in silicon block.

					The oxygen content impact resistivity and minority carrier lifetime, and the carbon content impact the brittleness of silicon. But what is the standard, how to solve the problems ......

					The minority carrier lifetime of the Si wafer is the key parameter, which directly determines the efficiency of solar cells. how can we get the real results, what kind of method is reliable ....

					Wafer broken with many reasons. In addition to human factors, itself flatness, the C content exceeded and so on, all these also can cause broken. Reduce costs, improve quality, please look at how to solve?

					The black heart and black side are serious problems affecting power generation efficiency of solar cells. How to better solve customer problems is the aim of our concerted efforts.
