Interfacial engineering of quantum dot-sensitized TiO2 fibrous electrodes for futuristic photoanodes in photovoltaic applications
Fibrous electrodes often suffer from poor adhesion, connectivity or efficiency. In an effort to solve this problem, Yong Soo Kang, Iván Mora-Seró and colleagues report a generic surface treatment approach to improve the electronic interface, and hence the photoanode performance, of quantum dot-sensitized TiO2 fiber electrodes. The team say that their interfacial engineering approach on fibrous membranes could improve the efficiency of photoanodes for range of applications including solar hydrogen generation via water splitting, hybrid (QDs–dye) excitonic solar cells, and light driven photocatalysts.
