➀ A study demonstrates that incorporating polymorphic FAPbI₃ perovskite nanofillers into PVDF films via 3D printing enhances triboelectric nanogenerator (TENG) performance;

➁ Annealing triggers a phase transition from δ to α-phase FAPbI₃, increasing PVDF’s β-phase content (up to 83%) and creating mesoporous structures for higher charge density;

➂ Resulting TENGs achieve 392 V peak-to-peak voltage and 2587 μW/cm² power density, offering scalable, sustainable energy solutions for microelectronics.

➀ Researchers from the Chinese Academy of Sciences have enhanced the efficiency and durability of flexible tandem solar cells by improving the bonding between layers.

➁ The perovskite top layer and CIGS bottom layer combination in these cells offers promise for lightweight, high-efficiency solar technology.

➂ After improvements, the flexible monolithic perovskite/CIGS tandem solar cell achieved a stabilized efficiency of 24.6%, showing strong mechanical durability and long-term stability.

➀ Researchers from Zhejiang University and the University of Cambridge have developed perovskite-based LEDs with pixels as small as a virus, potentially revolutionizing display technology.

➁ These LEDs, which are monochrome and measure 90 nanometers wide, offer brightness and efficiency comparable to conventional LEDs but face challenges in achieving full-color displays and long-term durability.

➂ While the smallest pixels may not be visible to the human eye, they could find applications in advanced technologies like augmented reality devices requiring ultra-high resolution.
