AI Customer ServiceA 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.
Silicon heterojunction (SHJ) solar cells have reached high power conversion efficiency owing to their effective passivating contact structures. Improvements in the optoelectronic properties of these contacts can enable higher device efficiency, thus further consolidating the commercial potential of SHJ technology.
The performance of SHJ solar cells with amorphous silicon and microcrystalline silicon front surface layers was compared. An efficiency of 23.87% (242.5 cm 2) and J SC = 39.19 mA/cm 2 for SHJ solar cell was achieved.
Wafer-based crystalline silicon (c-Si) solar cells are the dominant technology in the global PV market. Aiming at a higher PCE, technology iteration is occurring from the passivated emitter and rear cell (PERC) to tunnel oxide passivated contact (TOPCon) and silicon heterojunction (SHJ) solar cells 1, 2, 3, 4, 5, 6, 7.
In this paper, we implemented n-type hydrogenated microcrystalline silicon oxide (n-μc-SiOx :H) as the front surface field (FSF) to improve the short-circuit current density (J SC) of SHJ solar cells. The advantage of employing n-μc-SiO x:H layer is due to its low optical absorption coefficient and tunable refractive index.
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 larger than c-Si and it can be easily doped (either p- or n-type) [ 1 ] allowing the fabrication of electronic heterojunctions.
