Sulfur-enhanced surface passivation for hole-selective
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.

How thick is a silicon solar cell?
However, silicon's abundance, and its domination of the semiconductor manufacturing industry has made it difficult for other materials to compete. An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick.
What is a silicon solar cell?
Basic schematic of a silicon solar cell. The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market.
What is the limiting efficiency of a silicon solar cell?
The best real-world silicon solar cell to date, developed by Kaneka Corporation, is able to achieve 26.7% conversion efficiency 7, 8. A loss analysis of this 165 μm -thick, heterojunction IBC cell shows that in absence of any extrinsic loss mechanism the limiting efficiency of such a cell would be 29.1% 7.
What is the optimum solar cell thickness?
In traditional light trapping structures, the Lambertian limit is not achieved and the optimum solar cell thickness is much greater than 110 μm, as witnessed by the world-record-holding Kaneka cell.
Is silicon a good material for solar cells?
Yes, silicon is quite good for solar cells. Amongst all the other materials, silicon solar cells have superior optical, electronic, thermal, mechanical, and environmental properties. Q2. Are silicon solar cells thick? Yes, silicon solar cells have a thickness of 100-500 µm. They are made thick so that they are able to handle thin wafers.
How does a silicon solar cell work?
A silicon solar cell works the same way as other types of solar cells. When the sun rays fall on the silicon solar cells within the solar panels, they take the photons from the sunlight during the daylight hours and convert them into free electrons. The electrons pass through the electric wires and supply electric energy to the power grid.
