A silicon heterojunction (SHJ) solar cell is formed by a crystalline silicon (c-Si) wafer sandwiched between two wide bandgap layers, which serve as carrier-selective contacts. For c-Si SHJ solar cells, hydrogenated amorphous silicon (a-Si:H) films are particularly interesting materials to form these carrier-selective contacts. This is because the bandgap of a-Si:H is

Effective surface passivation is crucial for improving the performance of crystalline silicon solar cells. Wang et al. develop a sulfurization strategy that reduces the interfacial states and induces a surface electrical field at the same time. The approach significantly enhances the hole selectivity and, thus, the performance of solar cells.

1. Introduction Crystalline silicon heterojunction (SHJ) solar cell is currently one of the most mainstream high-efficiency solar cells, and its energy conversion efficiency has been up to 26.8% under the standard AM1.5 sun illumination [1 ].
The structure of an interdigitated back contact was adopted with our crystalline silicon heterojunction solar cells to reduce optical loss from a front grid electrode, a transparent conducting oxide (TCO) layer, and a-Si:H layers as an approach for exceeding the conversion efficiency of 25%.
Recently, the successful development of silicon heterojunction technology has significantly increased the power conversion efficiency (PCE) of crystalline silicon solar cells to 27.30%.
Eventually, we report a series of certified power conversion efficiencies of up to 26.81% and fill factors up to 86.59% on industry-grade silicon wafers (274 cm2, M6 size). Improvements in the power conversion efficiency of silicon heterojunction solar cells would consolidate their potential for commercialization.
Heterojunction cells combine a high photon absorbance of a thick silicon bulk material with the extraordinary passivation properties of amorphous silicon . Without losses in efficiency the thickness of Heterojunction solar cells can be reduced down to 80–100 µm. In Fig. 7.2 some typical examples for applications are presented.
