The full name of heterojunction technology is Heterojunction with Intrinsic Thin-layer, known as HJT, is a N-type bifacial solar cell technology, which uses N-type monocrystalline silicon as a substratum and deposits silicon-based thin films with different characteristics and transparent conductive films on the front and rear sides.
HJT solar cells combines the advantages of crystalline silicon and amorphous silicon thin film technology. With excellent photoabsorption and passivation effects, HJT has outstanding efficiency and performance, which make it as one of the technologies in the solar industry to improve conversion rate and power output to the highest level and also represents the trend of the new generation of solar cells platform technology.
