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…

Replacing lead in a leading type of next-generation solar cells has been tricky, as a promising substitute -- non-toxic tin perovskite -- couldn't hold up against the elements. Now, researchers have designed a tin-based perovskite with built-in protection against air and moisture.

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...

Just as left and right hands are mirror images, some molecules come in two "handed" forms. This property, called chirality, can influence not only how molecules interact with light but also which electron spins they allow to pass.

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.

Nature Sustainability, Published online: 13 August 2026; doi:10.1038/s41893-026-01916-6 Practical application of perovskite solar cells requires scalable fabrication in ambient environments. Here the authors introduce PNCC, a hole-transport co-polymer that enables ambient-fabricated devices to achieve certified efficiencies of 33.0% in tandem cells and 23.2% in modules.

Two-terminal (2T) perovskite/silicon tandem solar cells promise a major step beyond conventional silicon photovoltaics (PV), but their field performance depends on the color balance of sunlight as well as headline efficiency. A new study shows that shifting outdoor spectra can weaken current matching between the two sub-cells in 2T tandems, reducing energy output per watt under real skies.

Nature Communications, Published online: 11 August 2026; doi:10.1038/s41467-026-76713-y Perovskite–silicon tandem solar cells offer efficient, low-cost energy, but forming high-quality perovskite films on textured silicon remains challenging. Kong et al. applied a healing treatment that improved crystal growth, efficiency, and long-term stability.

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.

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.

Nature Communications, Published online: 24 June 2026; doi:10.1038/s41467-026-74288-2 Self-assembled monolayers are common hole-selective contacts in inverted perovskite solar cells, but acidic head groups reduce interface quality. Yang et al. neutralize these groups with alkali metal phosphonate salts and mixed layers, improving charge extraction, stability, and efficiency.
