Customer ServiceEffective 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.
Customer ServiceTo further promote the surface passivation and hole selectivity of the rear contact for high-performance p -Si solar cells, an additional ultrathin Al 2 O 3 film was employed as the passivation interlayer.
Metal contacts of high-efficiency cells do thus require an effective means of contact passivation. Today's PERC-type solar cells use high doping underneath the metal contacts as a means of contact passivation. Fig. 7 shows a schematic of the band diagram and the quasi-Fermi levels in the contacted region of a PERC device.
As an optimization of surface passivation in solar cells, an additional Al 2 O 3 film was deposited through ALD with a substrate temperature of 50°C after sulfurization, where one ALD cycle consists of 0.1 s trimethylaluminum (TMA; Al (CH 3) 3) pulse, 15 s N 2 (30 sccm) purge, 0.05 s H 2 O pulse, and 15 s N 2 purge.

Here, the key details of the model include the use of H atoms at one end of the silicon plate to terminate unsaturated bonds and fix the position of the silicon atoms away from the interface, thereby simulating the passivation effect of bulk Si in real scenarios.
In contrast to the extensive research on passivation for improving VOC, both experimental and theoretical investigations on the passivation effect on JSC are relatively rare. The JSC values are influenced by various factors, including the presence of defects and the optical properties of the solar cell.
