Check out our latest publication in ACS Photonics! Ultrathin crystalline silicon solar cells are light, flexible and use far less material, but they absorb near-infrared light poorly. In this work, we integrate hyperuniform disordered nanopatterns into 4.8 μm thick c-Si solar cells. These patterns combine the long-range uniformity of periodic structures with the broadband scattering of random ones. Because their spatial frequencies form a continuous band rather than discrete diffraction orders, they couple near-infrared light into guided modes over a broad spectral range. Congratulations to first author Alex! Many thanks to Esther Alarcon-Llado (AMOLF), Mark Brongersma (Stanford) and Marian Florescu (Southampton) for the great collaboration!
