6 Frequently Asked Questions about “What are black silicon solar cells”
What is a black silicon solar cell?
Black silicon is layered on the front surface, usually with another passivation layer. In a recent study by Savin et al., they have reported a record-breaking b-Si solar cell efficiency of 22.1% using an IBC configuration. Fig. 12 (b) shows the configuration of the solar cell used in their study.
What is black silicon (B-Si)?
One notable direction in the photovoltaics technology is the usage of black silicon (b-Si) for solar cells. Black-Si has textured surface, which can assist light trapping and improves efficiency of solar cells. Black-Si was first fabricated by Jansen et al. in 1995, and it exhibits a characteristic black surface colour.
Can black silicon solar cells be used for industrial production?
We demonstrate that efficiencies above 22% can be reached, even in thick interdigitated back-contacted cells, where carrier transport is very sensitive to front surface passivation. This means that the surface recombination issue has truly been solved and black silicon solar cells have real potential for industrial production.
How efficient is a black silicon-based solar cell?
Photograph of a black silicon-based solar cell with a reflectance of 1.79% by the PIII method is shown in Fig. 22 . The black silicon-based solar cell had an efficiency of 15.68% with a fill factor of 0.783. In contrast, the reference cell had an efficiency of 17.5% with a fill factor of 0.78. Fig. 22.
What is the power conversion efficiency of black silicon back-contacted solar cells?
A power conversion efficiency of 22% is achieved in black silicon back-contacted solar cells through passivation of the nanostructured surface by a conformal alumina layer.
Is black silicon a good material for photovoltaics?
Black silicon would also appear to be an ideal material for photovoltaics due to its outstanding light management properties under the solar spectrum. In addition to boosting efficiency, b-Si can provide significant savings in manufacturing costs as there is no need to deposit a separate antireflection coating.
