Abstract

Organic-inorganic perovskite is an emerging material possessing potential applications in solar cell, light-emitting diodes, and photodetectors due to its intrinsic features. High absorption coefficient, as an important parameter, is beneficial to the photo-electrical conversion efficiency and the relevant issues. Therefore, how to further improve the absorption is a meaningful topic. In this work, we turn to the nano-surface engineering to realize great absorption. Concretely, the self-assembled truncated spherical nanovoids are arranged on the surface of the perovskite. In comparison with the planar perovskite film, the absorption coefficient is increased by 18% on average within 300 nm ~ 800 nm wavelength region and a wide incident angle range. The improvement is originated from the special arrangement of effective dielectric constants which can be verified by multilayer effective media theory. This finding paves a way of improving the absorption of perovskite at the scales between the wavelength (perovskite-based gratings) and the quantum (perovskite with quantum dot doping). Moreover, the relevant research has been pointed out that the structured perovskite films have better pressure resistance.
