Summary: Tandem solar cells offer an attractive approach to increasing power-conversion-efficiency and achieving industry goals, by pairing wide-bandgap metal halide perovskites with complementary bandgap photovoltaic technologies. Comparative studies of 2-terminal and 4-terminal tandems, along with collective efforts to enhance performance, processing, and stability, have led to significant progress in the field. However, further research on mobile ion character and stability testing is crucial for improving perovskite tandems towards long-term outdoor operation.

Summary: This study investigates the effect of compositional range on light-induced phase-segregation phenomena in methylammonium lead bromide/iodide samples using simultaneous in situ XRD and PL measurements. The results suggest that the initial stage of photo-segregation can be rationalized by thermodynamic models, but the progression of phase segregation is also influenced by long-lived accumulative photo-induced material alterations. Additional photo-induced defects, such as halide vacancies and interstitials, should be considered to fully understand the mechanism of light-induced phase segregation.

Summary: Inorganic CsPbI3 perovskite solar cells show promise for tandem solar cells due to their excellent thermal stability and appropriate bandgap. The common method of using organic additives for intermediate phase engineering has been questioned regarding the full conversion to pure CsPbI3 phase. By studying the effect of annealing temperature, it is demonstrated that significant organic residues remain in the films when using the standard recipes of DMA(+)-assisted synthesis. However, increasing the annealing temperature to 340 degrees C eliminates the organic residues and leads to improved properties.

Summary: The authors demonstrate that adjustable ink viscosity can prevent ribbing effects when coating large-area halide perovskite layers. By adding acetonitrile as a co-solvent, smooth and high-quality FAPbI(3) thin-films are obtained. Scaling devices to larger areas, a power conversion efficiency of 17.1% is achieved in laser series-interconnected mini-modules. However, outdoor stability testing shows a decline in performance during warmer summer months.

Summary: Significant development has been made in optoelectronic applications using lead halide perovskites. This study investigates the interfacial energetics between the molecular layer of TIPS-pentacene and lead halide perovskite single crystals. The findings show that the energy levels of TIPS-pentacene shift towards higher binding energies with increasing thickness, while the perovskite energy levels remain unaffected. These results are important for assessing the energy alignment at perovskite/organic transport material interfaces.
