Dopant-free heterojunction opens new doors to highly efficient silicon solar cells with interdigitated back-contacts (IBC) via an easy hard-mask processing. However, the existence of inevitable overlap between the hole- and electron-transport layers may cause edge leakage and recombination, which will deteriorate the power conversion efficiency.

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.

Lines are guides to the eye. For the low-temperature solar cell (black squares in Figure 3), the FF increases significantly from 41.9 % in the as-deposited state to 50.9% after 120 min annealing at 120 °C. Simultaneously, the series resistance of the device R s is reduced from 40.3 to 33.7 Ω cm 2. The collection voltage follows the trend of the FF, increasing considerably
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.
Three key solar cell areas are highlighted by the vertical blue lines: 8.7 cm 2 (area of cells in this work), 156 cm 2 (standard 5-inch wafer) and 243 cm 2 (standard 6-inch wafer). (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article). 6. Conclusion
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.
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 ]. 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 [ 9 ].
Passivation of the b-Si surface reduces the number of dangling bonds on the surface, hence reducing surface defects and the probability for carriers to recombine. This ultimately improves the carrier lifetime and efficiency of the solar cell.
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.
