“…As a result, we obtained a relatively low PCE compared with the world records, suggesting that we have to improve both the quality of the perovskite layer and the UV transmittance of Eu‐complex PDMS films by decreasing surface roughness and so on.

Summary Organic‐inorganic lead halide perovskite solar cells (PSCs) have shown excellent characteristics for photovoltaic performance along with high power conversion efficiency (PCE) of 25.5%. Methylammonium lead iodide (CH3NH3PbI3) PSCs show effective photovoltaic performance but exhibit low utilization and instability in the ultraviolet (UV) region due to photodegradation. Therefore, there is a need for research aimed at increasing the stability of PSCs. Through their down‐conversion, PSCs can achieve high photovoltaic performance and stability by protecting against UV light and light‐harvesting in the visible region. In this study, europium (Eu; a lanthanide) was demonstrated to enhance the efficiency of PSCs and prevent degradation by UV light. The Eu‐complex poly(dimethylsiloxane) (PDMS) film enhanced the usability of the UV region by down‐converting UV light to visible light. In addition, Eu‐complex PDMS film has the advantages of being transparent and hydrophobic. Furthermore, it is easily detachable when the surface is contaminated. When Eu‐complex PDMS film was attached and compared with a reference device, it was confirmed that the PCE increased by up to 20% and that the short‐circuit current density also increased. Overall, Eu‐complex film was shown to increase the light‐harvesting of PSCs and enhance the stability in the UV region through the down‐conversion of UV light to visible light.

Organic halide salt passivation is considered to be an essential strategy to reduce defects in state-of-the-art perovskite solar cells (PSCs). This strategy, however, suffers from the inevitable formation of in-plane favored two-dimensional (2D) perovskite layers with impaired charge transport, especially under thermal conditions, impeding photovoltaic performance and device scale-up. To overcome this limitation, we studied the energy barrier of 2D perovskite formation from ortho-, meta- and para-isomers of (phenylene)di(ethylammonium) iodide (PDEAI2) that were designed for tailored defect passivation. Treatment with the most sterically hindered ortho-isomer not only prevents the formation of surficial 2D perovskite film, even at elevated temperatures, but also maximizes the passivation effect on both shallow- and deep-level defects. The ensuing PSCs achieve an efficiency of 23.9% with long-term operational stability (over 1000 hours). Importantly, a record efficiency of 21.4% for the perovskite module with an active area of 26 cm2 was achieved.

Metal halide perovskite have shown great potential for applications in photovoltaics, light‐emitting diodes and photon detectors, mainly owing to their superb optoelectronic properties, low‐cost raw materials and facile fabrication process. Although, polycrystalline perovskite thin‐films have been actively investigated for preparing various optoelectronic devices, the presence of detrimental defects at grain boundaries, serious ion migration and limited stability unfortunately hinder their device performance and practical application. As a contrast, perovskite single crystals (SCs) exhibit no grain boundaries, much lower trap density and much improved stability, hence providing a more attractive choice for not only optoelectronic device applications but also fundamental research. In this review, recent progress in the growth methods of perovskite SCs is summarized, followed by giving a detailed introduction of the intrinsic properties of perovskite SCs including optical properties, defects, charge carrier dynamics, ion migration and stability. On these base, the applications of perovskite SCs in various optoelectronic devices like solar cells, photodetectors, and radiation detectors are discussed, where the relationship between the composition, device architecture and device performance is highlighted. Finally, a tentative discussion on the current challenges and future opportunities in the development of perovskite SCs and optoelectronic devices is presented.
