“…Gallium selenides are important in photocatalysis, as transistors, as photodetectors, in photovoltaic devices where they are doped by copper and indium, in solar cells, in phase change recording media, and as a part of chalcogenide glasses . Gallium forms gallium selenide (GaSe) and digallium selenide (Ga 2 Se 3 ) compounds . The structure of Ga 2 Se 3 with one‐third vacant cation sites is similar to that of the mineral sphalerite (ZnS) .…”

Rationale Gallium selenide thin films important for electronics and phase‐change materials are prepared via pulsed laser deposition (PLD); however, there are no studies concerning the analysis of gallium selenide clusters formed in the gas phase. Laser desorption ionisation (LDI) combined with time‐of‐flight mass spectrometry (TOF‐MS) has great potential to generate charged GamSen clusters, to analyse them and thus to develop new materials. Methods LDI of Ga‐Se mixtures using a pulsed laser (337 nm nitrogen) was used to generate gallium‐selenide clusters. Mass spectra were recorded (in positive and negative ion mode) on a TOF mass spectrometer equipped with a quadrupole ion trap and reflectron mass analyser. Results Ga‐Se mixtures were found to be suitable for laser ablation synthesis (LAS) of gallium selenide clusters, although their composition was strongly dependent on the laser energy. The effect of laser energy on the stoichiometry of the generated clusters was established. In total, over 100 gallium selenide GamSen clusters were generated and identified from Ga‐Se mixtures. LDI of Ga2Se3 crystals showed almost the same clusters up to m/z 1000 with lower intensities, whereas no clusters from Ga2Se3 were observed above m/z 1000. Conclusions A family of over 100 gallium selenide clusters, generated and identified for the first time, shows rich and complex chemistry. Some of the clusters represent new compounds that have the potential to be used in the development of advanced materials.

Flexible Perowskit‐Solarzellen werden aufgrund ihres vielversprechenden Potentials in der tragbaren Elektronik intensiv erforscht. Verschiedene Niedertemperatur‐Herstellungsmethoden für Perowskitfilme und große Fortschritte bei der gezielten Abstimmung der Schnittstellen und Elektrodenmaterialien haben zu Effizienzen von über 18 % geführt. Dieser Aufsatz diskutiert die jüngsten Entwicklungen bei flexiblen Perowskit‐Solarzellen mit Schwerpunkt auf: 1) Niedertemperatur‐Herstellungsmethoden zur Verbesserung der Eigenschaften von Perowskitfilmen, wie vollständige Bedeckung, einheitliche Morphologie und gute Kristallinität; 2) Schnittstellen/Grenzflächen in flexiblen Perowskit‐Solarzellen, einschließlich Kennzahlen wie Transmissionsgrad, Ladungsträgerbeweglichkeit, Bandlückenabstand; 3) mechanische und Umgebungsstabilität flexibler Perowskit‐Solarzellen; 4) Ausblick auf flexible Perowskit‐Solarzellen in tragbaren Elektronikgeräten und deren Kosten; 5) Perspektiven zur Kommerzialisierung flexibler Perowskit‐Solarzellen.

BiFeO 3 (BFO) is a potentially important Pb-free ferroelectric with a narrow bandgap and is expected to become a novel photodetector. The photocurrent in BFO 3 strongly depends on the temperature but only a few studies have investigated in detail the relationships between photocurrent and temperature. Here, the temperature-dependent photocurrent and the corresponding photosensing properties of a Ag/BFO/indiumtin oxide (ITO) photodetector based on an optimized planar-structured electrode configuration are investigated. The photocurrent and responsivity of the BFO 3 -based photodetector can first be increased and then be decreased with increasing temperature. The largest photocurrent and responsivity can reach 51.5 µA and 6.56 × 10 −4 A W −1 at 66.1 °C, which is enhanced 126.3% as compared with that at room temperature. This may be caused by the temperature-modulated bandgap and barrier height in Ag/BFO/ITO device. This study clarifies the relationship between photosensing performance and the operating temperature of BFO-based photodetector and will push forward the application of ferroelectric materials in photoelectric field.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201906232. above mentioned solar cells, ferroelectric materials, which can exhibit abnormal photovoltaic effect evidencing by above bandgap photovoltage, have attracted much attention. [6][7][8][9][10] By contrast with traditional solar cells, the mechanism of the photovoltaic effect in ferroelectric materials is totally different. Moreover, the particular photovoltaic effect with ferroelectrics may have more chances to break the energy conversion limit in conventional solar cells. [11] Among the traditional ferroelectric materials, the photovoltaic properties of BiFeO 3 (BFO) films and single crystals are extensive studied because of its narrow bandgap near 2.7 eV. [12][13][14] Early investigations have been focused on the fundamental science attempting to explain the origins and working principles of ferroelectric photovoltaic effect as well as adoption of practical methods to improve the photovoltaic performances. Due to the appearance of different abnormal photovoltaic properties on BFO devices, four theories are proposed involving bulk photovoltaic effect, [15,16] domain wall theory, [17] Schottky-junction effect [18,19] and depolarization field effect. [20,21] In recent years, The largely reduced bandgap can cover the entire visible range, resulting in that a high power conversion efficiency of 8.1% has been achieved on Bi 2 FeCrO 6 thin film. [22] However, such a power conversion efficiency is still far below the commercialized Si-based solar cells (22%).Moreover, without being used as a solar cell aiming to generate large-scale electricity, ferroelectric devices with small-scale electricity generation can simultaneously be a photodetector to detect incident light. [23][24][25][26] As compared with the conventional battery-powered counterparts, the self-powered photodete...
