This progress will greatly improve the efficiency of silicon used in photovoltaic cells. While the theory behind black silicon has been around for some time, various different production methods have been developed that are opening the door for the future application of black silicon to the solar cell industry.
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.
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.
Fabricated black silicon surfaces can achieve reflectance less than 5% in the visible light spectrum. 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.
Paradoxically, the structure simultaneously brings severe carrier recombination and rarely increases efficiency. In our work, we combined the black silicon with TOPCon solar cell and fabricated high-efficiency TOPCon solar cells with nanopore pyramid structure emitter prepared by reactive ion etching.
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.
