Introduction of HJT Heterojunction technology (HJT) is a n type bifacial solar cell technology, by leveraging N-type monocrystalline silicon as a substratum and depositing silicon-based thin films with different characteristics and transparent conductive films on the front and rear surfaces respectively. Combining with the benefits of crystalline silicon and amorphous silicon thin-fim technologies, HJT technology has excellent photoabsorption and passivation effects,

are one of the technologies to improve the conversion rate and power output to the highest level, also represent the trend of the new generation of solar cell platform technology.

Higher Conversion Efficiency

solar cell uses α-Si thin-film as passivation materials to reduce the loss caused by the migration, which could increase the open circuit voltage to 750mV and guarantee the efficiency up to 24% at beginning.
