What is the structure of a heterojunction solar cell?

On the back side, an electron collecting stack is used, and it is composed of an intrinsic a-Si:H passivation layer, a doped n-type amorphous silicon (both deposited by PECVD), a TCO layer and a metallic contacting layer (deposited by PVD).

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 a silicon heterojunction solar cell (SHJ)?

Among them, the silicon heterojunction solar cells (SHJ) provide both high performance together with a perspective of low-cost fabrication and decrease of silicon wafers thickness bellow 100 µm [ 2 ].

What is the efficiency of silicon heterojunction solar cells?

"Very Thin (56 μm) Silicon Heterojunction Solar Cells with an Efficiency of 23.3% and an Open-Circuit Voltage of 754 mV". Solar RRL. 5 (11): 2100634. doi: 10.1002/solr.202100634. ISSN 2367-198X. S2CID 240543541. ^ Woodhouse, Michael A.; Smith, Brittany; Ramdas, Ashwin; Margolis, Robert M. (2019-02-15).

What is a front-junction solar cell?

A "front-junction" heterojunction solar cell is composed of a p–i–n–i–n -doped stack of silicon layers; the middle being an n -type crystalline silicon wafer and the others being amorphous thin layers.

Are heterojunction solar cells compatible with IBC technology?

Heterojunction solar cells are compatible with IBC technology, ie. the cell metallisation is entirely on the back surface. A Heterojunction IBC cell is often abbreviated to HBC.
