چکیده

Abstract Hydrogen is a promising future sustainable fuel candidate with boundless opportunities. Research into photoelectrochemical (PEC) water splitting based on lead halide perovskite (LHP) has progressed significantly the aim of more efficient solar hydrogen production. Herein, we unite well‐known photo‐absorbing LHP cost‐effective water‐splitting catalysts, and introduce two types monolithic LHP‐based PEC devices that act as photocathode photoanode for evolution reaction oxygen reaction, leading to unbiased overall splitting. Through integration these photoelectrodes, an solar‐to‐hydrogen conversion efficiency 10.64% photocurrent density 8.65 mA cm −2 are achieved.

Color-stable water-dispersed cesium lead halide perovskite nanocrystals.

Cesium lead halide perovskite nanocrystals are being lately explored for optoelectronic applications due to their emission tunability, high photoluminescence quantum yields, and narrow emission bands. Nevertheless, their incompatibility with polar solvents and composition homogenization driven by a fast anion-exchange are still important drawbacks to overcome. Herein we report on a successful e...

Bipolar TiO,/Pt Semiconductor Photoelectrodes and Multielectrode Arrays for Unassisted Photolytic Water Splitting

Bipolar Ti02/Pt photoelectrodes were fabricated by anodization of thin Ti foils onto which Pt had been previously sputter-deposited. These photoelectrodes are capable of a vectorial charge transfer. Current-potential curves were used to predict the behavior of multielectrode arrays. Several different multielectrode cells, utilizing KOH, O2 electrolytes, were constructed. In series configuration...

Ultrathin Colloidal Cesium Lead Halide Perovskite Nanowires.

Highly uniform single crystal ultrathin CsPbBr3 nanowires (NWs) with diameter of 2.2 ± 0.2 nm and length up to several microns were successfully synthesized and purified using a catalyst-free colloidal synthesis method followed by a stepwise purification strategy. The NWs have bright photoluminescence (PL) with a photoluminescence quantum yield (PLQY) of about 30% after surface treatment. Large...

Inorganic hole conductor-based lead halide perovskite solar cells with 12.4% conversion efficiency.

Organo-lead halide perovskites have attracted much attention for solar cell applications due to their unique optical and electrical properties. With either low-temperature solution processing or vacuum evaporation, the overall conversion efficiencies of perovskite solar cells with organic hole-transporting material were quickly improved to over 15% during the last 2 years. However, the organic ...
