What is a band diagram of HJT solar cell?

A band diagram of the standard HJT solar cell is sketched in Fig. 1b .The i-a-Si:H film, as a buffer layer, enables a low c-Si surface recombination via excellent chemical passivation .

How to create high-efficiency HJT structure solar cells?

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.

How do solar cells form a heterojunction?

In the first design version of these solar cells, the heterojunction was formed by using the flat n-type crystalline silicon wafer with a thin layer of p-type amorphous hydrogenated silicon (a-Si:H) deposited on its surface . The efficiency of this structure reached 12.3%.

What are heterojunction solar cells (HJT)?

Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps.

What is the difference between standard and HJT solar cells?

Standard (homojunction) solar cells are manufactured with c-Si for the n-type and p-type layers of the absorbing layer. HJT technology, instead, combines wafer-based PV technology (standard) with thin-film technology, providing heterojunction solar cells with their best features. Structure of HJT solar cell - Source: De Wolf, S. et al.

What is the concentration of charge carriers in a HJT solar cell?

According to the works ( , p. 0111), the concentration of the main charge carriers of the p-type emitter layer in the HJT solar cell should be at least 2 × 10 20 cm −3. Unfortunately, there are not so many works on the study of the influence of the concentration of charge carriers of the layers on a solar cell operation. 3.
