A photoelectrochemical (PEC) cell is able to realize effective solar‐to‐hydrogen energy conversion from water by using the semiconductor photoelectrode. Semiconducting colloidal quantum dots (QDs) with captivating features of size‐tunable optoelectronic properties and broad light absorption are regarded as promising photosensitizers in solar‐driven PEC systems. Up to now, different types of QDs have...
Bias‐Free Water Splitting
In article number 2204495, Xin Tong, Lianzhou Wang, Zhiming M. Wang, and co‐workers develop a quantum dots (QDs)‐based photoelectrochemical (PEC) device comprised of tandem Zn‐doped CuInS2 QDs‐decorated metal oxide electrodes (BiVO4 and Cu2O) for bias‐free solar water splitting. Both the ligands capped on QDs and QDs‐electrode heterojunctions are rationally engineered to...
A cost‐effective and high‐efficiency photoelectrochemical (PEC) water splitting system based on colloidal quantum dots (QDs) represents a potential solar‐to‐hydrogen (STH) conversion technology to achieve future carbon neutrality. Herein, a self‐biased PEC cell consisting of BiVO4 photoanode and Cu2O photocathode both decorated with Zn‐doped CuInS2 (ZCIS) QDs is successfully fabricated. The intrinsic...
