“…This successful spreading of interest in applications relies on the low cost and superior photophysical properties of CsPbBr 3 , including higher stability against high humidity and thermal environmental conditions compared with organic and hybrid perovskites, high chemical stability, high melting point (> 500 °C), large absorption coefficient, wide color gamut, high stability against photobleaching, robustness against humid environments, high photoluminescence quantum yields and narrow emission linewidths, photoluminescence emission tunable by changing the composition, high electron mobility and long electron life time, high defect tolerance, and low-threshold lasing [2][3][4][5][6][7]. Nowadays, all-inorganic CsPbBr 3 are exploited in numerous applicative fields [8][9][10][11][12], including photovoltaics [13][14][15][16], lasing [17], light-emitting diodes [18,19], photodetectors [20], colorconversion layers [21], high-energy radiation detection [22], clinical radiotherapy [23], and scintillators [24].…”

All-inorganic perovskites are widely investigated as a new generation of materials thanks to their superior optoelectronic properties and better stability than hybrid organic–inorganic perovskites. In particular, cesium lead bromide (CsPbBr3) exhibits advantageous properties for numerous applicative fields (photovoltaics, light-emitting diodes, photodetectors, lasing, field effect transistors, and ionizing radiation detectors). The performance of CsPbBr3 being critically dependent on the deposition technique, proper understanding and optimization of the fabrication process are demanding. Despite the well-known potentiality of the Pulsed Laser Deposition (PLD) technique in depositing films with complex stoichiometry, a very limited number of literature studies report on the successful deposition of CsPbBr3 films by PLD. Recently, the authors disclosed the impact of the uneven masses of Cs, Pb, and Br on the film stoichiometry and guidelines to recover the desired composition. Herein, we exploit stoichiometric mechano-chemically synthesized targets to deposit, by nanosecond-PLD (λ = 248 nm, τ = 20 ns, room temperature, fluence of 1 J/cm2), CsPbBr3 films to be studied following time aging, thermal heating and exposure to high relative humidity. Even in the presence of the characteristic absorption peak at ~ 520 nm, the freshly deposited film shows no photoluminescence. Photoluminescence is switched on by thermal annealing (at 250 and 350 °C) or after a few days (at least 15) of exposure to air and it persists over time. Films present interesting morphology evolution and oxygen adsorption following heating.

“…The PL spectrum (Figure 4b) of FTO/TiO 2 /CsPbBr 3 sample shows a narrow emission at 525 nm with an FWHM of 25 nm at an excitation wavelength of 400 nm, agreeing with previous reports for CsPbBr 3 perovskite materials. 6 Accordingly, the FTO/TiO 2 /CsPbBr 3 sample showed a bright green fluorescence under a manual UV light lamp irradiation (inset of Figure 4b). The ambient stability of the FTO/TiO 2 /CsPbBr 3 sample without special storage conditions was monitored for 1 week by XRD and UV−vis absorption measurements (Figure S2).…”

“…Metal-halide perovskites have attracted great attention in the past two decades for many applications, − such as solar cells, − light-emitting diodes, , photodetectors, , and, most recently, photocatalysis, − due to their unique optoelectronic properties including tunable band gap, low exciton binding energy, and long carrier lifetime, along with simple preparation techniques and low material cost. All-inorganic halide perovskite quantum dots (QDs) have emerged in the past decade with promising stability if compared with their hybrid organic–inorganic perovskite counterparts. − …”

Herein, we report the in situ photocatalytic deposition of cesium lead bromide (CsPbBr 3 ) perovskite quantum dots on mesoporous TiO 2 -coated fluorine-doped tin oxide (FTO/TiO 2 ) electrodes. The mesoporous TiO 2 layer is used as a photocatalyst to promote the following: (1) the Pb deposition from a Pb 2+ aqueous solution and (2) the in situ Pb conversion into CsPbBr 3 perovskite in the presence of a CsBr methanolic solution without any organic capping agent. Both steps are carried out under ultraviolet light irradiation under ambient conditions without any post-treatment. The obtained FTO/TiO 2 /CsPbBr 3 film was characterized by UV–vis diffuse reflectance spectroscopy, X-ray diffraction, photoluminescence spectroscopy, scanning electron microscopy, and transmission electron microscopy. The FTO/TiO 2 /CsPbBr 3 heterojunction exhibited enhanced visible-light photodegradation activity demonstrated for the oxidation of curcumin organic dye as a model system. The novel and simple approach to fabricating a supported photocatalyst represents a scalable general method to use semiconductors as a platform to incorporate different perovskites, either all-inorganic or hybrid, for optoelectronic applications. The perovskite deposition method mediated by the UV light at room temperature could be further applied to flexible and wearable solar power electronics.

“…In recent years, organic–inorganic hybrid perovskite solar cells (PSCs) have attracted widespread attention due to their unique photoelectric properties, and the highest certified power conversion efficiency (PCE) has soared from 3.8 to 25.5%. , However, the Joule heat generated during the long-term operation of the equipment causes the volatilization of organic cations, decomposes the film, and shortens the service life, which limits practical commercial applications. − The all-inorganic perovskite material CsPbI x Br 3– x ( x is in the range of 0–3) is considered to be the most promising material to solve this problem due to its excellent thermal stability. − Among them, the narrow-band gap (1.68–1.73 eV) CsPbI 3 achieved an excellent PCE of 20.8% . Unfortunately, CsPbI 3 quickly transforms into a non-photosensitive phase (δ-CsPbI 3 ) due to the critical phase instability even under encapsulation conditions .…”

The all-inorganic CsPbIBr2 perovskite solar cells (PSCs) have been developed quickly in the past few years due to their photoelectric features and excellent stability. However, the disadvantages of high defect density and short carrier lifetime of CsPbIBr2 perovskites result in the inability to improve the power conversion efficiency (PCE) of batteries and hinder their practical application. Here, we prove that doping an appropriate amount of Zn(Ac)2 (0.2%, at.) in CsPbIBr2 PSCs can improve crystal quality, decrease trap density, and optimize charge recombination. Therefore, the PCE of the 0.2 mol % Zn(Ac)2-doped CsPbIBr2 PSC has been improved from 8.23 to 10.65%, and the improvement rate has reached 29%. In addition, the unencapsulated Zn2+ and Ac– co-doped device has better long-term stability in an ambient atmosphere. The method can effectively increase the PCE and stability of carbon-based CsPbIBr2 PSCs, which also provides a reference direction for future commercial applications.
