Chinese scientists achieved reversible red-green photoluminescence switching in Mn-based metal halides by replacing free Cl⁻ with Br⁻. The responsive property stems from weakened hydrogen ...

Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current.

Inverted perovskite solar cells offer strong potential for scalable, low-cost solar power, but a hidden interface inside the ...

A research team from The Hong Kong University of Science and Technology (HKUST) has developed GrainBot, an AI-enabled toolkit that automatically extracts and quantifies multiple microstructural ...

A team from the Institute of Materials Science of Seville (ICMS), a joint center of the Spanish National Research Council (CSIC) and the University of Seville (US), has developed a new hybrid device ...

Tiny crystal “seeds” could solve a hidden flaw in perovskite solar cells—unlocking high efficiency at larger scales.

Regular perovskite solar cells (PSCs)—which place the electron-transport layer beneath the perovskite absorber and the hole-transport layer on top—have limitations with respect to large-scale ...

A new material uses its organic part to produce faster and stronger light under radiation, helping improve speed and efficiency in radiation detectors.

An AI-powered toolkit automatically extracts and quantifies microstructural features from microscopy images, accelerating ...
