Bio-inspired design strategy of quasi-random structures for optimal light control
We report a new design strategy for quasi-random nanophotonic structures by directly representing structures in Fourier space. We validated the method both numerically and experimentally by optimizing light-trapping structures in a thin-film solar cell and achieved 2.3-fold absorption enhancement.
