“…Texturing of the light-absorbing layer in a solar cell can greatly improve its efficiency due to optimization of light-scattering 3 and, in particular increase the efficiency of silicon-perovskite tandems up to 25.5%. 4–6 Simulation studies suggest large improvement of the efficiencies for the nanopatterned perovskite films 7–10 that was also confirmed experimentally. 11 …”

“…[113] Light-trapping strategy is crucial to the light leaking and reflection. [114,115] Micro-nano structure arrays have drawn extensive attention due to their effective photon management to reach or even exceed the Yablonovitch limit of 4η 2 that the absorption enhancement factor of photoactive materials in theory, where η is the refractive index of photoactive material. [35,[116][117][118] By means of the interaction of incident light and micro-nano structure, the optical path is prolonged and the incident photon is trapped in the photoactive layer to produce the standing wave in the photoactive layer and enhance absorbance of incident photon.…”

Metal halide perovskite, an emerging photosensitive semiconductor, has been widely employed in solar cells, light‐emitting diodes, photodetectors, and lasers owing to its excellent photophysical properties and simple solution preparation processing. However, as a photoactive layer, the higher refractive index and thinner thickness of perovskite film can cause reflection and transmission at the interface, and confine the emitted light within devices, resulting in the poor incident photon absorption and emitted photon extraction. In addition, the intrinsic brittleness of perovskite material restricts its potential applications in flexible optoelectronics. Therefore, great effort has been put into micro‐nano structured perovskite optoelectronics, and the reported reviews mainly focus on the fabrication process of micro‐nano patterned perovskite. Herein, the functionalities of micro‐nano structures in optoelectronics, including improving the light trapping, light extraction, light modulation, carrier dynamics, mechanical robustness, and other novel functionalities, are comprehensively reviewed. The specific applications of these functionalities in perovskite‐based optoelectronic devices are then discussed in detail to provide a better understanding of the photophysical properties of micro‐nano structure functionalized optoelectronics. Finally, promising strategies to promote the multifunctional commercial applications of micro‐nano structured perovskite optoelectronics are provided.

“…One of the most interesting characteristics of the method proposed here to enhance the PCE is the fact that this TiO 2 –SiO 2 nanocomposite is obtained through a simple mixing step, indicating the feasibility of the proposed method easily upscalable. There are other light-trapping mechanisms, as nanotextures, 31 that theoretically can achieve a higher enhancement, but require a complicated fabrication method that is difficult to transfer to industrial applications.…”

In this work, SiO2 nanoparticles (NPs) were integrated into the mesoporous TiO2 layer of a perovskite solar cell to investigate their effect on cell performance. Different concentrations of SiO2/ethanol have been combined in TiO2/ethanol to prepare pastes for the fabrication of the mesoporous layer with which perovskite solar cells have been fabricated. Addition of SiO2 NPs of 50 and 100 nm sizes produces an enhancement of cell performance mainly because of an improvement of the photocurrent. This increment is in good agreement with the theoretical predictions based on light scattering induced by dielectric SiO2 NPs. The samples using modified scaffolds with NPs also present a significant lower current–potential hysteresis indicating that NP incorporation also affects the ion accumulation at the perovskite interface, providing an additional beneficial effect. The results stress the importance of the appropriated management of the optical properties on further optimization of perovskite solar cell technology.
