Summary: This study investigates the effects of different additives on the performance of perovskite solar cells. It is found that cesium can stabilize the perovskite phase, while chlorine can increase the size and crystallinity of the perovskite crystals, thereby improving the overall device performance. Additionally, modifying the interface between the hole transport layer and the perovskite layer can further enhance the photovoltaic characteristics of the perovskite solar cells.

Summary: Highly emissive CsxFA1_xPbI3 perovskite films, which can be used in tunable near-infrared LEDs, were fabricated using an alkaline-interface-assisted cation-exchange method. The Cs-FA ion-exchange barrier was effectively eliminated, enabling the formation of phase-pure CsxFA1_xPbI3 films with tunable emissions. The resulting NIR perovskite LEDs demonstrated high external quantum efficiencies, high radiances, and high power conversion efficiencies, representing the best performance in a similar region.

Summary: This study reports a pure-iodide wide-band-gap perovskite top cell that is almost free from halide segregation. Cs and dimethylammonium cations were simultaneously incorporated into the A-site of the perovskite to increase the band gap while maintaining the tolerance factor. However, the incorporation of dual cations resulted in the formation of orthorhombic and hexagonal phases instead of the pure perovskite phase.

Summary: A transformation strategy mediated by an inorganic ligand (NOBF4) was developed to obtain blue-emitting CsPbBr3 nanoplates (NPLs). The transformation process involved the dissolution and recrystallization of Cs4PbBr6 nanocrystals in a nonpolar environment, resulting in the formation of pure blue-emitting NPLs with a line width of about 12 nm. The reorganization of organic ligands tuned by NO+ played a crucial role in the formation of NPLs. This work provides an effective strategy for obtaining pure blue-emitting NPLs and offers a platform for exploring the mechanism of anisotropic growth in perovskite crystals.

Summary: All-inorganic and organic-inorganic hybrid perovskite solar cells (PSCs) have achieved a significant breakthrough in terms of high performance and low-cost solution processability. They have reached an efficiency of around 26%, comparable to conventional inorganic photovoltaics. The stability of the photoactive black phase of CsPbI3 and FAPbI(3) perovskites has been a fundamental problem, hindering their application in photovoltaic devices. Various methods, such as dimensional and compositional engineering, have been employed to stabilize the black phase and enhance their stability.

Summary: This study demonstrates the use of vapor phase infiltration (VPI) to create hybrid organic-inorganic layers, improving the stability of organic charge transport layers in perovskite solar cells (PSCs). By infiltrating TiOx via VPI, the crystallization of the spiro-OMeTAD layer is hindered, preventing N-N stacking of the molecules. The infiltrated PSCs retained over 80% of their original efficiency after a 200-hour stability test at 75 degrees C, while devices without infiltration rapidly decreased in efficiency within the first 50 hours. This work provides a blueprint for stabilizing organic charge transport layers using VPI and preventing deleterious crystallization that shortens device lifetimes.

Summary: The composition-dependent degradation of hybrid organic-inorganic perovskites (HOIPs) due to environmental stressors still hinders their commercialization. Machine learning models using high-throughput, in situ photoluminescence (PL) are implemented to predict the response of Cs(y)FA(1-y)Pb(Br(x)I(1-)x)(3) under relative humidity cycles. Accurate time-series forecasts with an accuracy of >90% are achieved, showing potential for data-centric approaches in accelerating material development for clean-energy devices.

Summary: In this study, we explore the use of excitation correlation spectroscopy to detect nonlinear photophysical dynamics in two different semiconductor classes, namely lead-halide perovskite (LHP) solar cells and single-component organic-semiconductor diodes. By measuring the time-integrated photoluminescence or photocurrent component as a function of inter-pulse delay, we found distinct differences in the photophysics of these two systems when comparing measurements with the two detection schemes.
