1.The HJT cell is designed with conductive TCO surface and insulation-free layer, so there is no build-up surface layer charge.
2.Compared to PERC module, HJT features lower power temperature coefficient and higher output power.It is about 4.9% more efficient in power output than PERC module under 60℃ operation temperature.
3.The effective power generation time of HJT is 11.07% more than the effective power generation time of conventional cells.

HJT is considered one of the top cell technologies with highest bifaciality. Higher bifaciality allows more energy yield on the back.Generally, it enables 5%-30% energy gain on the back, depending on the factors such as ground reflection, region type etc.
HJT modules adopt the production technology of low-temperature ribbon and low temperature flux, bring much lower damage for the cells, granting reliability and performance comparable to that of PERC.
