We develop a man-made leaf from a stable all-oxide-based photoelectrochemical tandem device that can sustainably produce fuels from sunlight and water without requiring any external electrical power input.
We demonstrate NaBiS2 to be capable of absorbing as much light as silicon, but with 10,000 times lower thickness. This is enabled by cation disorder, which also leads to unusual effects on charge-carrier kinetics.
We unravel the complex electron-phonon coupling in BiOI, showing single crystals to have long charge-carrier drift lengths. This enables these materials to be capable of detecting ultra-low dose rates of X-rays, which can give rise to safer medical imaging.
The core limitation of using halide perovskites commercially is their composition of neurotoxic lead that can easily be released into water due to the high solubility of the perovskite compound. This editorial discusses the use of supramolecular complexes to prevent lead leaching from broken perovskite modules.
