Over the past decade, halide perovskite systems have captured widespread attention among researchers since their exceptional photovoltaic (PV) performance is disclosed. The unique combination of optoelectronic properties and solution processability shown by these materials has enabled perovskite solar cells (PSCs) to reach efficiencies higher than 25% at low fabrication costs. Moreover, PSCs display enormous potential for modern unconventional PV applications, since they can be made lightweight, semitransparent (ST), and/or flexible by means of appropriate design strategies. In particular, by enabling transparency and high efficiency simultaneously, ST‐PSCs hold great promise for future versatile utilization in the context of building‐integrated PVs (BIPVs) or as top cells to be coupled with conventional lower‐bandgap bottom cells in tandem PV devices. The present review aims to provide a detailed overview of latest research about ST‐PSCs for BIPVs and tandems, by critically reporting on the most updated and effective design strategies in view of these two possible future applications. The differences and similarities between the available approaches are punctually highlighted, emphasizing the importance of a rigorous application‐orientated ST‐PSC design. Finally, the main challenges and issues about device design, operation, and stability that need to be addressed before commercialization are thoroughly scanned.

In the past decade, lead halide perovskites have been intensively explored due to their promising future in photovoltaics. Owing to their remarkable material properties such as solution processability, nice defect tolerance, broad bandgap tunability, high quantum yields, large refractive index, and strong nonlinear effects, this family of materials has also shown advantages in many other optoelectronic devices including microlasers, photodetectors, waveguides, and metasurfaces. Very recently, the stability of perovskite devices has been improved with the optimization of synthesis methods and device architectures. It is widely accepted that it is the time to integrate all the perovskite devices into a real system. However, for integrated photonic circuits, the shapes and distributions of chemically synthesized perovskites are quite random and not suitable for integration. Consequently, controlled synthesis and the top‐down fabrication process are highly desirable to break the barriers. Herein, the developments of patterning and integration techniques for halide perovskites, as well as the structure/function relationships, are systematically reviewed. The recent progress in the study of optical responses originating from nanostructured perovskites is also presented. Lastly, the challenges and perspective for nanostructured‐perovskite devices are discussed.

“…When compared with the addition of reflective filters on the outer surfaces of PSCs, integrating the photonic structures within the PSCs dramatically minimized the angular variability of the perceived color. Wang et al [ 139 ] and Liu et al [ 140 ] created nanostructured ETLs by removing the PS microspheres after depositing the ETL. The colorful PSCs fabricated by Liu et al used an inverse opal‐structured SnO 2 and SnO 2 –TiO 2 composite and delivered PCEs of up to 16.8%; those made by Wang et al featured TiO 2 nanobowl arrays and exhibited PCEs of up to 16.94%.…”

Organic‐ and perovskite‐based optoelectronics, which merge excellent optoelectronic properties with potentially large and high‐throughput manufacturing, have attracted attention as emerging revolutionary technologies with considerable practical applications. Herein, the recent progresses in organic‐ and perovskite‐based photovoltaics and photodetectors with integration of judicious optical structure designs are summarized. The characterization and performance metrics of such devices from the perspectives of device architecture, physics, and material science are studied. Research related to devices having dielectric mirrors, diffracted Bragg reflectors/photonic crystals, microcavities, and 2D photonic structures as design elements is discussed. Some suggestions of promising directions for future studies are concluded.
