22. 23%! Chint single crystal p-type PERC ascension 0 + SE technology. 4% battery efficiency!

As the industry continues to develop, photovoltaic industry competition intensified, low cost, high efficiency become the common pursuit goal. Looking for a new technology is imperative, and the PERC + SE because of its efficient and compatible with production line effectively and is unanimously recognized in the industry. Chint new energy with industry pace, on the basis of the single crystal p-type PERC superposition SE laser technology, through the efforts of the technical personnel, the production efficiency reached 22 on average. 23%, the highest efficiency reached 22. 55%, the % of production line.

　　SE（ Selective Emitter） The selective emitter battery, the contact region between the electrode doped ( Low sheet resistance) Has a good ohmic contact, the electrode section shallow mixed ( High sheet resistance) With good spectral response.

LDSE technology because of its simple process, convenient for mass production, has been widely used in the industry, the current chengtai is also the technique. Chint mainly in light, laser SE technology diffusion, sintering, the slurry screen fitting optimization, etc. Through the optimization, chint PERC + laser SE average efficiency reached 22 of the battery. 23%, open pressure as high as 680 mv, a non SE battery efficiency 0. 4% in the industry at a higher level.

　　12. Emission reductions calculation: generally does not consider emissions and leakage of CDM project its own emissions, in addition to the geothermal project, see below.
