“…For perovskite cells, the tables now accept results based on “quasi‐steady‐state” measurements (sometimes called “stablilised” in the perovskite field, although this conflicts with usage in other areas of photovoltaics). Along with other emerging technologies, perovskite cells may not demonstrate the same level of stability as conventional cells, with the stability of perovskite cells discussed elsewhere …”

All‐Inorganic Halide Perovskites for Optoelectronics: Progress and Prospects

2017

During the past 8 years, solution‐processed organic–inorganic metal halide (OMH) perovskites have become some of the most notable materials because they can exhibit high solar cell efficiency, exceeding 20%. However, due to the volatile and hygroscopic nature of the organic cations, OMH perovskites suffer from chemical instability, especially at high temperatures. Therefore, all‐inorganic metal halide (IMH) perovskites (CsBX3, B = Pb, Sn, Ge; X = Cl, Br, I) are rapidly emerging as promising alternatives because of their superior stabilities and comparable properties, such as strong emission, high fluorescence quantum yield and tunable bandgap covering entire visible spectrum. Highlighted by these advantages, IMH perovskites have attracted enormous attention, indicating a promising future. In this review, the recent progress on the syntheses of IMH perovskites is outlined. In addition, the research development of IMH perovskites in optoelectronic devices, such as perovskite solar cells, photodetectors, and light‐emitting diodes, is introduced. Finally, the challenges facing the field of IMH perovskites are discussed and some possible solutions based on the available literature are suggested.

A rapid layer‐specific annealing on perovskite active layer enabled by ultraviolet (UV) light‐emitting diode (LED) is demonstrated and efficiency close to 19% is achieved in a simple planar inverted structure ITO/PEDOT:PSS/MAPbI3/PC71BM/Al without any device engineering. These results demonstrate that if the UV dosage is well managed, UV light is capable of annealing perovskite into high‐quality film rather than simply damaging it. Different in principle from other photonic treatment techniques that can heat up and damage underlying films, the UV‐LED‐annealing method enables layer‐specific annealing because LED light source is able to provide a specific UV wavelength for maximum light absorption of target film. Moreover, the layer‐specific photonic treatment allows accurate estimation of the crystallization energy required to form perovskite film at device quality level.
