Songyu new generation PE poly equipment

Songyu new generation PE poly equipment

With the national efforts to achieve carbon peaking and carbon neutralization, the entire energy system has been accelerating its transformation, especially photovoltaic power generation. Photovoltaic technology has also undergone generations of technological iterations, including a series of changes in silicon chip size and thickness. From the perspective of battery technology, traditional BSF technology, PERC technology, TOPCon/HJT/HPBC, TBC, etc, It is inseparable from the whole localization.

TOPCon boron expansion equipment solution

TOPCon boron expansion equipment solution

Under the background of national 2030 carbon peak and 2060 carbon neutral development, photovoltaic industry can be said to be one of the most important energy solutions. At present, the main products in the photovoltaic industry are single crystal PERC products, whose LCOE kilowatt hour power is close to the parity grid connection. If the parity grid connection and lower LCOE are achieved, large-scale and high power are the two main means; At present, on the basis of PERC platform, to further improve efficiency, there are two technical solutions: TOPCon battery and heterojunction HJT battery; In combination with industrial technology development and scale effect to achieve cost reduction control, heterojunction HJT batteries are expected to require a certain period of time to polish. Because TOPCon batteries share more than 80% of the equipment with PERC batteries, it can be predicted that explosive growth will occur in a very short time, and it is also the only choice to achieve efficiency of more than 24+%. Wuxi Songyu Technology has accumulated many years of experience in TOPCon battery production equipment and can provide TOPCon with the following equipment: boron phosphorus co expansion furnace, phosphorus/annealing co expansion furnace, LPCVD, PECVD (polycrystalline silicon three in one), ALD tubular atomic layer deposition aluminum oxide, PECVD (SiNx, SiON), etc.
