HJT Cells:
That is, amorphous silicon thin film heterojunction cells. It is a heterojunction composed of two different semiconductor materials. The crystalline silicon heterojunction solar cell (HJT) is a thin film of amorphous silicon deposited on crystalline silicon. It combines the advantages of crystalline silicon cells and thin film cells, and has the advantages of high conversion efficiency, low process temperature, high stability, low decay rate, With the advantages of double-sided power generation, the technology is subversive.
Why HJT？
The essence of cell technology iteration is that cost reduction and efficiency improvement, high efficiency and low cost are the direction of development.
HJT is the development direction of a new generation of cell technology because of its high photoelectric conversion efficiency, high bifacial ratio, simplified equipment process, low product light attenuation, strong stability, large space for cost reduction and efficiency enhancement, and broad prospects.
