Integrating surface nanotextures into thin crystalline-Si solar cells: The case of a 1-μm-thin nanoimprinted heterojunction cell

• Texturing of crystalline silicon at the light wavelength scale is a promising approach for light management in ever thinner cells. However, this approach requires adapting the device design and process, which has so far revealed to be a challenging task. Indeed, successful integration requires compromising the excellent optical properties for preserving the electrical ones. We briefly summarize what has been learned so far in the community and illustrate some of these learnings with the fabrication and improvement of 1-μm-thin monocrystalline nanotextured silicon solar cells.
