Large-scale and low-cost approaches for creating functional nanostructures are still not developed. An international team of researchers (Russia, Italy) has developed a method to create mesoporous electron transport layer based on optically resonant silicon nanoparticles incorporated into TiO paste to be applied for perovskite (MAPbI) solar cell. The inclusion of Mie-resonant silicon nanoparticles helps to improve light absorption by a perovskite layer without reduction of the active material. The management of Si nanoantennas concentration provides a power conversion efficiency higher than 21% by increasing all main device parameters. The new silicon nanoparticles provide physical understanding on the mechanisms of the device improvement as well as help to optimize the silicon nanoparticles concentration…read more.
