Black silicon is layered on the front surface, usually with another passivation layer. In a recent study by Savin et al. [ 6 ], 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.
Using only 3–20 μm -thick silicon, resulting in low bulk-recombination loss, our silicon solar cells are projected to achieve up to 31% conversion efficiency, using realistic values of surface recombination, Auger recombination and overall carrier lifetime.

A solar cell in its most fundamental form consists of a semiconductor light absorber with a specific energy band gap plus electron- and hole-selective contacts for charge carrier separation and extraction. Silicon solar cells have the advantage of using a photoactive absorber material that is abundant, stable, nontoxic, and well understood.
Black silicon solar cells achieve efficiencies higher than conventional cells. The main challenge is to minimize recombination due to increased surface area. Experimental data are available for certain configurations but need improvement. Combined optical–electron–hole–phonon transport models are underdeveloped.
Black-Si is especially useful for photovoltaic applications due to its exceptional absorbing properties and low production cost [ 8 ]. 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 [ 5 ].
