Abstract Entire band light management is crucial for amorphous silicon (a-Si) solar cells, especially when the absorbing layer becomes ultrathin. Here, we propose and demonstrate a double-side texture strategy to effectively manage light in ultrathin solar cells via a simple and scalable nanoparticle imprinting technique. SiO<inf>2</inf> nanoparticles are half embedded into the top surface of the solar cells to introduce the double-side texture. Using a solar cell with a 150-nm thick a-Si layer as an example, we observe significant enhancement over the entire absorption band of a-Si both theoretically and experimentally. A maximum short circuit current density enhancement as high as 43.9% has been achieved experimentally compared with a flat solar cell.
