Nature, Published online: 09 September 2026; doi:10.1038/d41586-026-02709-9 When making mixed-halide perovskite films for use in solar cells, bromide-rich domains crystallize faster than iodide-rich ones do, leading to defects. Adding a molecule tuned to bind selectively to bromide-bound lead synchronizes the crystallization rates, yielding uniform films, better operating stability and a more-eff…

Scientists have found a way to make tin-based perovskite solar cells more efficient and longer-lasting by adding a specially selected molecule during manufacturing. Metal halide perovskite solar cells are considered promising alternatives to conventional silicon solar panels. They can be lightweight, flexible and relatively inexpensive to produce. Their shape can also be adjusted for use […] The …

A research team led by Dr. Sungjun Hong of the Photovoltaics Research Department at the Korea Institute of Energy Research (KIER) has developed a dual-molecule passivation technology that simultaneously improves the efficiency and stability of inverted perovskite solar cells. The research was conducted in collaboration with Professors Young Seok Park of Ulsan National Institute of Science and Tec…

Scientists have found a new way to improve highly efficient solar cells by adding an extremely thin layer of cesium chloride during production. The method helped a perovskite-silicon tandem solar cell convert 30.3% of incoming sunlight into electricity. Perovskite-silicon tandem cells combine two light-absorbing materials. Silicon captures part of the sunlight, while a perovskite layer […] The po…

Perovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscal...

A Nanjing Tech team has screen-printed every layer of a perovskite solar cell in ambient air, achieving 22.41 per cent efficiency without vacuum equipment or inert-atmosphere gloveboxes. Researchers at Nanjing Tech University have developed a perovskite solar cell in which every functional layer is screen-printed under ambient conditions. The work reports a power conversion efficiency […]

Lithuanian researchers stabilized inverted perovskite solar cells by converting an acidic component into a neutral salt, achieving high efficiency after 1,000 hours of use.

Mixed-halide perovskites make great wide-bandgap cells until they segregate. The problem starts at crystallization. A selective Lewis base syncs the mixed halides, yielding stable and efficient perovskite/organic tandem solar cells with a certified 27.0% efficiency.

To investigate the potential of barium-based halide perovskites for optoelectronic applications, we performed first-principles density functional theory calculations on XBaCl 3 (X = In, Tl). These calculations were performed using the WIEN2k package, which provides detailed insights into the materials' characteristics. The code provides a silent insight into materials’ characteristics and potenti…

Zhao et al. design a robust layered interconnection enabling efficient stacked perovskite devices with high efficiency, brightness and low voltage.

Nature Catalysis, Published online: 15 July 2026; doi:10.1038/s41929-026-01582-z Surface strontium (Sr) enrichment in perovskite oxides has long been associated with degraded oxygen electrocatalysis. Now, atomically precise control of SrO coverage under operating conditions shows a volcano-shaped structure–activity relationship, revealing that a single SrO surface layer maximizes oxygen incorpora…

Nature Communications, Published online: 15 July 2026; doi:10.1038/s41467-026-75629-x Perovskite solar cells face defects and interfacial strain that limit efficiency and stability, while standard chemical fixes can add stress. Yang et al. use low-temperature liquid-assisted vibration to remove defects and stress, improving efficiency, durability, and scalability.
