Density functional theory calculations predict that the new lead-free double perovskites A2LaAuCl6 with potassium, rubidium, or cesium are stable, wide-gap semiconductors with strong ultraviolet absorption and moderate high-temperature thermoelectric performance. Subject of Research: First-principles prediction of the electronic, optical, mechanical, and…
However, dye-sensitized solar cells for indoor light and perovskite solar cells for outdoor use are different technologies. Sekisui Chemical and Panasonic are ahead in terms of commercialization timing, and the production capacities announced by each company do not necessarily indicate…
A comprehensive review in Discover Nano examines how perovskite materials could serve sustainable technologies while warning that lead content, leaching and toxicity remain serious obstacles.
An AI-guided framework identified a readily synthesizable self-assembled monolayer that delivers 27.2% efficiency and retains over 95% of initial efficiency after 2,000 hours of testing at 65 °C. A team reporting in Nature Synthesis has now used artificial intelligence to search the enormous chemical…
A new DFT study predicts that the lead-free fluoride double perovskites Rb₂AuCoF₆ and Rb₂AuRhF₆ combine visible-range band gaps, strong absorption and promising thermoelectric figures of merit. News Source: Denise Maddox. (October 28, 2026). Computer models flag rubidium-gold fluoride perovskites as lead-free candidates for solar…
Researchers at the University of Oxford have discovered that bismuth sulfide material can overcome a major limitation in solar energy. The problem was that materials that absorb sunlight strongly usually lose electrical charge too quickly to generate efficient power. The…
A study led by the University of Oxford has identified a novel semiconductor that overcomes a key limitation with light-harvesting materials. The results, published today in Nature, could enable more efficient solar panels with higher outputs. Solar energy currently faces…
Japanese imaging and electronics company Ricoh has announced plans to begin producing perovskite solar cells in Japan by 2030. The factory will be located at Ricoh Industry Co., Ltd.’s Tohoku site in Shibata, Miyagi prefecture, northern Japan, and will use…
A lead-free dual-phase Cs3BiBr6@Cs3Bi2Br9 perovskite embedded in PVDF-HFP shows enhanced β-phase content and improved local piezoelectric response with increasing filler concentration. Researchers have synthesized dual-phase, lead-free perovskite nanocrystals of Cs3BiBr6@Cs3Bi2Br9 (CBB) and embedded them in a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) polymer matrix…
Perovskite solar cells often appear in the news as "thin and lightweight next-generation solar cells." However, just from the name, it is not clear how they differ from the familiar panels (silicon) on roofs, or why they are worthy of…
Perovskite and perovskite-silicon tandem solar cells: efficiency records, stability, lead-free and printable perovskites, and the move to manufacturing.
