Article Synopsis
- Photoelectrochemical (PEC) artificial leaves are innovative devices that integrate light harvesting and catalysis for sustainable solar fuel production, but current manufacturing techniques hinder their scalability due to weight and fragility.
- The research showcases the development of lightweight artificial leaves using thin, flexible materials, achieving impressive hydrogen production rates and selectivity for CO reduction with lead halide perovskite photocathodes and catalysts.
- Excitingly, the technology demonstrated potential for larger-scale applications with stand-alone devices maintaining performance and stability, as well as ability to float during outdoor testing, suggesting future possibilities for using these systems in open water without competing for land resources.
We report the controlled and selective doping of colloidal PbSe nanowire arrays to define pn junctions for electronic and optoelectronic applications. The nanowires are remotely doped through their surface, p-type by exposure to oxygen and n-type by introducing a stoichiometric imbalance in favor of excess lead. By employing a patternable poly(methyl)methacrylate blocking layer, we define pn junctions in the nanowires along their length.
