BiVO4/WO3/SnO2 Double-Heterojunction Photoanode with Enhanced Charge Separation and Visible-Transparency for Bias-Free Solar Water-Splitting with a Perovskite Solar Cell
Ji Hyun Baek,Byeong Jo Kim,Gill Sang Han,Sung Won Hwang,Dong Rip Kim,In Sun Cho,Hyun Suk Jung +6 more
TL;DR: A double-heterojunction concept based on a BiVO4/WO3/SnO2 triple-layer planar heterojunction (TPH) photoanode, which shows simultaneous improvements in the charge transport and transmittance and bias-free and stable solar water-splitting by constructing a tandem PEC device with a perovskite solar cell.
Journal ArticleDOI
Selective and Efficient Gd-Doped BiVO4 Photoanode for Two-Electron Water Oxidation to H2O2
Ji Hyun Baek,Ji Hyun Baek,Thomas Mark Gill,Hadi Abroshan,Sangwook Park,Xinjian Shi,Jens K. Nørskov,Jens K. Nørskov,Hyun Suk Jung,Samira Siahrostami,Xiaolin Zheng +10 more
TL;DR: In this article, the authors predict that doping BiVO4 with optimal concentrations of gadolinium (Gd) not only enhances its activity for H2O2 production but also improves its stability.
Journal ArticleDOI
A Zn:BiVO4/Mo:BiVO4 homojunction as an efficient photoanode for photoelectrochemical water splitting
Jae Myeong Lee,Ji Hyun Baek,Ji Hyun Baek,Thomas Mark Gill,Xinjian Shi,Sang Myeong Lee,In Sun Cho,Hyun Suk Jung,Xiaolin Zheng +8 more
TL;DR: In this article, an n−n+ type-II homojunction of Zn:BiVO4/Mo:Bi VO4, which improves the bulk transport and surface charge transfer processes of the well-studied BiVO4 photoanode, is reported.
Journal ArticleDOI
Rapid Flame-Annealed CuFe2O4 as Efficient Photocathode for Photoelectrochemical Hydrogen Production
Sangwook Park,Ji Hyun Baek,Ji Hyun Baek,Liang Zhang,Jae Myeong Lee,Kevin H. Stone,In Sun Cho,Jinghua Guo,Hyun Suk Jung,Xiaolin Zheng +9 more
TL;DR: Copper ferrite (CuFe2O4) possesses an indirect bandgap in the range of 1.54-1.95 eV as mentioned in this paper, and is used as an attractive p-type photocathode in photoelectrochemical (PEC) water splitting.
Journal ArticleDOI
