Data From China National PV and Energy Storage Experimental Platform：N-Type TOPCon Module Has Better Power Generation

Jolywood module has low temperature coefficient, high efficiency, and high power output ,high bifaciality, high reliability and low degradation compared with other types of modules. It can generate more power while other conditions keep the same. Jolywood also developed J-TOPCon 2.0 technology in house based on no winding and in-situ doping etc, which makes the cell efficiency increase. Currently, the highest efficiency of mass production can reach 24.8%. In addition, the lab efficiency of Jolywood 182mm N-type cell exceed 26.1 in November.

In the first three quarters of 2022, the experimental data show that the back side of the module has the maximum group irradiation under cloudy weather. Daqing is located in a high latitude area, the sunlight will directly irradiate the back side of the modules at sunrise and sunset. When the sun irradiates the back side of the modules for more than 4 hours, it accounts for about 20% of the accumulated daily irradiation of the back side of the modules. The empirical experimental data show that N-type high-efficiency modules have the best power generation performance, especially N-Type TOPCon module. It will represent the future development direction of module technology. N-Type TOPCon techonolgy has LETID/LID Free impurities, lower temperature coefficient, better Anti-PID performance and longer lifetime. In addition, N-Type TOPCon technology also doesn't have B-O defect.

As a leader in the PV industry, Jolywood will continue to produce high-quality products and promote global energy transformation in the world.
