At the end of 2022, LONGi Solar released a single junction commercial HJT cell efficiency of 26.81% . These high-efficiency data show that HJT is so far the best performance technology for single junction solar cells. The performance of HJT cells can be improved by post-treatment of completed cells, either light-thermal or electro-thermal.

The demand for Silicon heterojunction solar cells (HJT) has significantly grown recently. These solar cells have gained recognition for their remarkable performance, which can be attributed to the exceptional passivation properties of bilayers consisting of intrinsic and doped hydrogenated amorphous silicon.
However, one of the most significant steps made for creation of new high-efficiency HJT structure solar cells was the idea of the using of the intrinsic conductivity a-Si:H as a buffer layer between the doped emitter and the silicon wafer which led to reduction of the dangling bond densities and densities of defects at the interface.
