Elucidation of the opto-electronic and photoelectrochemical properties of FeVO₄ photoanodes for solar water oxidation

Abstract

Molybdenum doping in FeVO4 photoanodes enhances the charge carrier mobility and lifetime, resulting in a 45% AM1.5 photocurrent increase.

Mitigating voltage losses in photoelectrochemical cell scale-up

“…Signicant research efforts are therefore directed towards developing novel complex oxides with smaller bandgaps (1.7-1.9 eV) to replace BiVO 4 . [13][14][15][16][17][18] In addition, given the impressive development of solar water splitting devices, the next step is to shi beyond the laboratory experiments and demonstrate large-scale devices. Scaling can be quantied by the power of a device and can be increased by concentrating the solar irradiation or by increasing the photoabsorber area.…”

High Throughput Discovery of Effective Metal Doping in FeVO4 for Photoelectrochemical Water Splitting

“…Several groups have reported the fabrication of FeVO 4 thin films using magnetron cosputtering, spray pyrolysis, dropcasting, and sol-gel methods with reported bandgap energy of 2.0-2.1 eV. [21][22][23][24][25][26][27][28][29][30][31] However, the achieved photocurrents are still very low as compared with the theoretical photocurrent based on the bandgap energy. We have previously identified that the main problem causing the low performance of FeVO 4 films is the poor bulk carrier separation.…”

Transformation of oxide ceramic textiles from insulation to conduction at room temperature

“…However, the materials are commonly hard and brittle. Moreover, they exhibit poor electronic conductivity due to the large bandgap (3)(4)(5). Conductive ceramic textiles that could be reversibly bent, polymer-like characteristic, would be extremely attractive for use in myriad engineering applications such as wearable electronics and energies.…”
