“…The critical compressive strain was found to be related to the adhesive thickness, as it was about 0.2% for 2.0 mm adhesive and 0.5% for 0.5 mm adhesive, as also shown in Table 6. Similar experiments were conducted in [32] where the a-Si PV cells were bonded by polyimide tapes and the critical strain was 0.5%. Therefore, the critical strains for a-Si PV cells in compression were much smaller than those in tension.…”

“…Tensile tests were conducted on a-Si PV cell specimens with a larger dimension (1700 × 1000 mm 2 ) and the critical tensile strain when an obvious reduction in the power output was reported as 1.5% in [98]. According to similar tensile experiments on a-Si PV cells in other research, the critical strain was determined to be about 1.4 [96] and 1.0% [32,105]. Therefore, the critical tensile strain for a-Si PV cells ranges from 0.8 to 1.6%, suggesting their feasibility in load-carrying scenarios for buildings.…”

“…For example, dye-sensitive PV cells were encapsulated in translucent glass fiber reinforced polymer (GFRP) laminates for BIPV applications [44], and they were also experimentally investigated for window applications [45]. Perovskite PV cells were subjected to tensile loading to evaluate the feasibility for BIPV applications in loadcarrying scenarios [32]. However, BIPV applications in large scale practices with these PV technologies are still limited, and their information is, therefore, not included in Table 1.…”

“…The perovskite material is an emerging technology, and they have been made into thin-film or flexible PV cells, transparent or with different colors, while most of them are currently not commercially available [56]. Effects of tensile strain on thin-film flexible Perovskite PV cells have been investigated for further BIPV applications, as reported in [32].…”

“…Second, mechanical status also affects the power output of BIPV applications [32,33], and integrated PV cells may be subjected to certain mechanical strain, although they are supposed to be applied in scenarios without structural loads. Studies have been conducted to understand the strain effects on the electrical performance of the PV cells, but systematic review is required to understand the applicable mechanical scenarios for different types of PV cells.…”

Building integrated photovoltaic (BIPV) technologies are promising and practical for sustainable energy harvesting in buildings. BIPV products are commercially available, but their electrical power outputs in practice are negatively affected by several factors in outdoor environments. Performance improvement of BIPV applications requires mitigation approaches based on an understanding of these factors. A review was, therefore, conducted on this issue in order to providing guidance for practical applications in terms of the selection of proper PV technologies, temperature management, solar irradiation enhancement and avoidance of excessive mechanical strain. First, major types of PV cells used in BIPV applications were comparatively studied in terms of their electrical performances in laboratorial and outdoor environments. Second, temperature elevations were widely reported in outdoor BIPV applications, which may cause efficiency degradation, and the mitigation approaches may include air-flow ventilation, water circulation and utilization of phase change materials. The heat collected from the PV cells may also be further utilized. Third, mechanical strains may be transferred to the integrated PV cells in BIPV applications, and their effects on electrical performance PV cells were also discussed. In addition, the power output of BIPV systems increases with the solar irradiation received by the PV cells, which may be improved in terms of the location, azimuth and tilt of the cells and the transmittance of surface glazing. Suggestions for practical applications and further research opportunities were, therefore, provided.

In recent years, halide perovskite materials have been used to make high performance solar cell and light‐emitting devices. However, material defects still limit device performance and stability. Here, we use synchrotron‐based Bragg Coherent Diffraction Imaging to visualise nanoscale strain fields, such as those local to defects, in halide perovskite microcrystals. We find significant strain heterogeneity within MAPbBr3 (MA = CH3NH3+) crystals in spite of their high optoelectronic quality, and identify both 〈100〉 and 〈110〉 edge dislocations through analysis of their local strain fields. By imaging these defects and strain fields in situ under continuous illumination, we uncover dramatic light‐induced dislocation migration across hundreds of nanometers. Further, by selectively studying crystals that are damaged by the X‐ray beam, we correlate large dislocation densities and increased nanoscale strains with material degradation and substantially altered optoelectronic properties assessed using photoluminescence microscopy measurements. Our results demonstrate the dynamic nature of extended defects and strain in halide perovskites, which will have important consequences for device performance and operational stability.This article is protected by copyright.

Flexible perovskite solar cells (f‐PSCs) as a promising power source have grabbed surging attention from academia and industry specialists by integrating with different wearable and portable electronics. With the development of low‐temperature solution preparation technology and the application of different engineering strategies, the power conversion efficiency of f‐PSCs has approached 24%. Due to the inherent properties and application scenarios of f‐PSCs, the study of strain in these devices is recognized as one of the key factors in obtaining ideal devices and promoting commercialization. The strains mainly from the change of bond and lattice volume can promote phase transformation, induce decomposition of perovskite film, decrease mechanical stability, etc. However, the effect of strain on the performance of f‐PSCs has not been systematically summarized yet. Herein, the sources of strain, evaluation methods, impacts on f‐PSCs, and the engineering strategies to modulate strain are summarized. Furthermore, the problems and future challenges in this regard are raised, and solutions and outlooks are offered. This review is dedicated to summarizing and enhancing the research into the strain of f‐PSCs to provide some new insights that can further improve the optoelectronic performance and stability of flexible devices.
