“…The quality of CsPbIBr 2 thin films largely determines the efficiency of PSC devices. Various studies have been widely carried out for improving CsPbIBr 2 crystallinity via interfacial modification and annealing engineering, [45][46][47][48][49][50][51][52][53] but little attention has been paid to the growth process of CsPbIBr 2 crystals before annealing.…”

Among all‐inorganic perovskites, CsPbIBr2 has become a potential candidate in semitransparent perovskite solar cells (ST‐PSCs) due to its excellent thermal stability and suitable bandgap. Herein, by optimizing the ambient temperature in an N2‐filled glovebox, the growth process of CsPbIBr2 crystals is regulated to avoid the generation of pinholes and improve the photoelectric conversion capacity of perovskite cells. When the ambient temperature is around 25 °C, the champion power conversion efficiency (PCE) of 10.82% with opaque n–i–p structure is achieved. Based on MoOx/Ag/MoOx (20/12/20 nm) multilayer top electrode, the ST‐PSC device achieves a maximum PCE of 7.06% at the fluorine‐doped tin oxide side under the simulated 1 sun illumination condition and a PCE of 23.96% at MoOx/Ag/MoOx electrode side under the intensity of 1000 lux (≈350 μW cm−2) provided by a white light‐emitting diode lamp, along with an average visible transmittance of 29.25%. The resulting perovskite solar cell is the first bifacial inorganic ST‐PSC that could be used under both sunlight and indoor light, which is an important step toward all‐day power generation of inorganic ST‐PSCs and building‐integrated photovoltaics.

“…Interface engineering is one of the main methods used to reduce defects in perovskite film, obtain better band alignment and improve the device performance. [34][35][36][37] Huang and coworkers developed a method to deposit the CsPbBr 3 quantum dots (QDs) on the perovskite film. The QDs passivated the defects, optimized the film morphology, and improved the device efficiency up to 11.10%.…”

Wide‐bandgap inorganic cesium lead halide CsPbIBr2 is a popular optoelectronic material that researchers are interested in because of the character that balances the power conversion efficiency and stability of solar cells. It also has great potential in semitransparent solar cells, indoor photovoltaics, and as a subcell for tandem solar cells. Although CsPbIBr2‐based devices have achieved good performance, the open‐circuit voltage (Voc) of CsPbIBr2‐based perovskite solar cells (PSCs) is still lower, and it is critical to further reduce large energy losses (Eloss). Herein, a strategy is proposed for achieving surface p‐type doping for CsPbIBr2‐based perovskite for the first time, using 1,5‐Diaminopentane dihydroiodide at the perovskite surface to improve hole extraction efficiency. Meanwhile, the adjusted energy levels reduce Eloss and improve Voc of the CsPbIBr2 PSCs. Furthermore, the Cs‐ and Br‐vacancies at the interface are filled, reducing structural disorder and defect states and thus improving the quality of the perovskite film. As a result, the target device achieves a high efficiency of 11.02% with a Voc of 1.33 V, which is among the best values. In addition to the improved performance, the stability of the target device under various conditions is enhanced, and the lead leakage is effectively suppressed.

“…A circular bioeconomy implies the sustainability of resource-efficient biorefinery in production chains. During this process, emissions will be reduced using residues and waste as feedstock and optimizing the critical process parameters. − Upcycling waste biomass, especially agricultural residues, into sustainable fuel will promote circular economic development by minimizing waste and carbon-neutral. Therefore, the synthesis of sustainable fuel from biomass-derived compounds has gained constant interest. − Cyclopentanone is a biomass-derived platform molecule that could be generated by the hydrolysis–dehydration of hemicellulose .…”

Self-condensation of biomass-derived cyclopentanone is an attractive reaction for sustainable aviation fuel production. Ball-milling is an effective method for this reaction. However, the effect of process parameters on product yield has not been explored and is still unclear. In this work, the process parameters in the ball-milling process are optimized by orthogonal experiment and subsequently investigated by the response surface methodology. Rotate speed is a critical index for dimer yield, and catalyst dosage is an essential index for trimer yield and selectivity. In addition, a life cycle assessment of both ball-milling and magnetic stirring methods is conducted to reveal the difference between the two methods. The ball-milling method shows relatively excellent economic and environmental potential impact, especially for the toxic consumption of marine aquatic organisms, which is a 38.2% reduction compared to the magnetic stirring method. The ball-milling method introduced in cyclopentanone self-condensation is more sustainable and economical than the magnetic stirring method.
