“…65 However, the first low noise MHP photodiodes were reported in 2015 almost at the same time by four research groups, [66][67][68][69] and the reason behind this relatively long delay is important: metal halide perovskites were initially deployed in metal oxide mesoporous scaffolds, which are not suitable for photodetection due to their large capacitances. Planar junctions became more common in 2014, 70 however solution processing of these junctions was not an easy task.…”

“…In all of these reports, D* ~10 12 Jones and EQEs of 60 to 80% in the visible were achieved. Lin et al 66 showed that the response speed in these photodiodes is RCtime limited i.e., the second term of eq. 1 dominates, obtaining a response time of 120 ns as shown by Fang et al 69 This is predominantly because of the large dielectric constant of metal halide perovskites (70 to 30 from static to 1 MHz frequencies).…”

“…For small pixels, it has been shown that the response speed becomes carrier transit time limited and response speed could exceed MHz in MHP photodiodes. 66,67,69 As with organic semiconductor photodiodes, the electro-optical properties of MHPs can be tuned by changing the composition of the perovskite material (Fig. 2d).…”

“…Perovskite solar cells are not only used as energy conversion devices but can also act as photodetectors [18][19][20][21][22][23][24]. In reports by Lin et al [18], their photodetectors possessed a high detectivity beyond 10 12 Jones and a PCE of more than 12%.…”

An ultraviolet (UV)-visible tunable photodetector based on ZnO nanorod arrays (NAs)/perovskite heterojunction solar cell structures is presented, in which the ZnO NAs are prepared using the hydrothermal method and annealed in different atmospheres. Based on solar cell structure perovskite photodetectors, it exhibited highly repeatable and stable photoelectric response characteristics. In addition, the devices with ZnO NAs annealed in a vacuum showed a high responsivity of about 10 14 cm Hz 1/2 W −1 in the visible region, whereas the devices with ZnO NAs annealed in air exhibited good detectivity in the UV region, especially at around 350 nm. Furthermore, when the annealing atmosphere of the ZnO nanorods was changed from vacuum to air, the dominant detection region of the photodetectors was altered from the visible to the ultraviolet region. These results enable potential applications of the ZnO NAs/perovskite photodetectors in ultraviolet and visible regions.

“…The recent discovery of the favorable properties of methyl ammonium lead halide perovskite materials has triggered a paradigm shift in what is possible in optoelectronics. Stoichiometric wavelength tunability, low trap state density, solution-phase processability, as well as excellent light absorption and emission, make these materials well suited to applications in solar cells (12)(13)(14)(15), light-emitting diodes (16,17), photodetectors (18,19), and lasers (20)(21)(22).…”

The rapidly growing field of nanoscale lasers can be advanced through the discovery of new, tunable light sources. The emission wavelength tunability demonstrated in perovskite materials is an attractive property for nanoscale lasers. Whereas organic-inorganic lead halide perovskite materials are known for their instability, cesium lead halides offer a robust alternative without sacrificing emission tunability or ease of synthesis. Here, we report the low-temperature, solution-phase growth of cesium lead halide nanowires exhibiting low-threshold lasing and high stability. The as-grown nanowires are single crystalline with well-formed facets, and act as high-quality laser cavities. The nanowires display excellent stability while stored and handled under ambient conditions over the course of weeks. Upon optical excitation, Fabry-Pérot lasing occurs in CsPbBr 3 nanowires with an onset of 5 μJ cm −2 with the nanowire cavity displaying a maximum quality factor of 1,009 ± 5. Lasing under constant, pulsed excitation can be maintained for over 1 h, the equivalent of 10 9 excitation cycles, and lasing persists upon exposure to ambient atmosphere. Wavelength tunability in the green and blue regions of the spectrum in conjunction with excellent stability makes these nanowire lasers attractive for device fabrication.nanowire | perovskite | laser | inorganic | stability M iniaturized light sources hold great promise for advancing the field of optoelectronics. The development of highly stable, wavelength-tunable light sources on the nanoscale can unlock the potential for commercial applications in optical communications (1, 2), sensing (3), imaging (4), and data storage (5), among many others. Nanowire lasers represent one promising approach toward miniaturized light sources. Acting both as the laser cavity and gain medium (6), nanowires may be easily incorporated into optoelectronic circuits based on their size as well as recent advances in electrical pumping (7-10). A wide range of nanowire lasers has been reported consisting of a multitude of compositions including many II-VI and III-V semiconductors (11). Unfortunately, fabrication of many of these nanowires requires expensive hightemperature or low-pressure conditions. Additionally, whereas most are stable under ambient conditions, only a few of these materials have demonstrated broad wavelength tunability. The recent discovery of the favorable properties of methyl ammonium lead halide perovskite materials has triggered a paradigm shift in what is possible in optoelectronics. Stoichiometric wavelength tunability, low trap state density, solution-phase processability, as well as excellent light absorption and emission, make these materials well suited to applications in solar cells (12-15), light-emitting diodes (16, 17), photodetectors (18, 19), and lasers (20)(21)(22).Recently, Zhu et al. reported low lasing thresholds and recordbreaking quality factors for methyl ammonium lead halide (CH 3 NH 3 PbX 3 , X = I, Br, Cl) nanowire lasers as well as excellent wavelength tuna...
