Black silicon solar cells with interdigitated back-contacts achieve
Here we show that a conformal alumina film can solve the issue of surface recombination in black silicon solar cells by providing chemical and electrical passivation. 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.

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 a black Si solar cell?
Black-Si-based solar cells are capable of achieving a similar or even higher efficiency than industry-standard Si solar cells at a lower production cost . As of January 2018, b-Si dominates about 30% of the multicrystalline Si solar cell market and holds a market value of $16 billion a year .
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.
