N-type battery TOPCon is the best choice for technology transition.
TOPCon (Tunnel Oxide Passivated Contact) - oxide layer passivated contact. There is no essential difference between the front side and conventional N-type solar cells or N-PERT solar cells, and the core technology of the battery is the passivation contact on the backside. The back of the battery is composed of a layer of ultra-thin silicon oxide (1~2nm) and a layer of phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. The passivation performance is activated by the annealing process, and the crystallinity of the Si film changes during the annealing process, from microcrystalline amorphous mixed phase to polycrystalline. Annealed at an annealing temperature of 850°C, iVoc>710mV, J0 in 9-13fA/cm2, showing excellent passivation performance of passivated contact structure.
This structure can prevent the recombination of minority carriers and holes, and increase the open circuit voltage and short circuit current of the battery. The ultra-thin oxide layer can allow many electrons to tunnel into the polysilicon layer while blocking the recombination of minority electrons and holes. The good passivation effect of ultra-thin silicon oxide and heavily doped silicon film makes the surface energy band of the silicon wafer bend, thus forming field passivation As a result, the probability of electron tunneling is greatly increased, the contact resistance is reduced, and the open circuit voltage and short circuit current of the battery are increased, thereby improving the conversion efficiency of the battery.
Double-sided single glass enhances the safety of n-type TOPCon modules
1) n-type TOPCon batteries are not afraid of the risk of acetic acid corrosion
In high-temperature and high-humidity areas, the battery is often subject to acetic acid corrosion caused by the hydrolysis of the glue film, which leads to a significant drop in module power. To solve this problem, the n-type TOPCon battery uses an inorganic acetic acid-resistant slurry (slurry number JHZ04) to reduce the power of the module. The corrosion strength of the front glass is also adjusted with the expansion coefficient of the silver powder, thereby improving the acetic acid resistance, so that the n-type TOPCon battery does not need to worry about the risk of the battery being corroded and attenuated due to the formation of acetic acid due to the hydrolysis of the EVA film.
2) Transparent mesh backplane with high water resistance
Since most photovoltaic modules are packaged in EVA, it is inevitable that EVA will be hydrolyzed to produce acetic acid in high-temperature and high-humidity environments. To solve the troublesome water vapor problem, Jolywood New Materials adopts the latest "Haobo 2.0" technology, through multi-layer Molecular-level structure design, forming a dense molecular structure on the surface of the transparent grid backplane, effectively blocking the penetration of water vapor; forming organic/inorganic hybridization at the gap where the underlying inorganic molecules are doped into the polymer chain segments, reducing water vapor channels, thereby achieving high Water blocking effect.
3) The transparent back panel is safe without bursting
The double-sided double-glass module uses 2.0mm glass on the front and back, and the glass burst probability is 6‰; while the double-sided single-glass The most important thing is the transparent grid backplane, which can pass through the infrared band above 3μm and dissipate heat through infrared radiation. Compared with double glass, the average operating temperature is 1-2℃ lower, so there is basically no need to worry about the risk of glass bursting.
