Journal ArticleDOI
Enabling unassisted solar water splitting by iron oxide and silicon.
Ji-Wook Jang,Chun Du,Yifan Ye,Yongjing Lin,Xiahui Yao,James E. Thorne,Erik Y. Liu,Gregory McMahon,Junfa Zhu,Ali Javey,Jinghua Guo,Dunwei Wang +11 more
TL;DR: It is shown that, by using the prototypical photoanode material of haematite as a study tool, structural disorders on or near the surfaces are important causes of the low photovoltages.
Journal ArticleDOI
Hematite-based water splitting with low turn-on voltages.
Chun Du,Xiaogang Yang,Matthew T. Mayer,Henry Hoyt,Jin Xie,Gregory McMahon,Gregory Bischoping,Dunwei Wang +7 more
TL;DR: Hematite was chosen as a prototypical system for these proof-of-concept demonstrations because it is an earth-abundant material with great promise for high-efficiency, low-cost water splitting and the fundamental reason for the observed limited photovoltage generation by hematite lies in the relatively positive positions of its valenceand conduction-band edges.
Journal ArticleDOI
Hematite/Si nanowire dual-absorber system for photoelectrochemical water splitting at low applied potentials.
TL;DR: This work addresses a critical challenge of using hematite for PEC water splitting, namely, the fact that the band-edge positions are too positive for high-efficiency water splitting.
Journal ArticleDOI
Improving hematite-based photoelectrochemical water splitting with ultrathin TiO2 by atomic layer deposition.
Xiaogang Yang,Xiaogang Yang,Rui Liu,Chun Du,Pengcheng Dai,Pengcheng Dai,Zhi Zheng,Dunwei Wang +7 more
TL;DR: It was shown that the surface treatment by ultrathin TiO2 led to better charge separation, less surface charge recombination and, hence, greater photovoltage by hematite.
Journal ArticleDOI
What Limits the Performance of Ta3N5 for Solar Water Splitting
Yumin He,James E. Thorne,Cheng Hao Wu,Peiyan Ma,Peiyan Ma,Chun Du,Qi Dong,Jinghua Guo,Dunwei Wang +8 more
TL;DR: In this paper, a combination of photoelectrochemical and high-resolution electron microscope measurements was used to understand the origins of the photoactivity degradation on Tantalum nitride (Ta 3 N 5 ).
