Abstract

Liquid diffusion occurs throughout an ordered multilayer hollow sphere array of a transparent conducting oxide supporting large photocurrents.

Carbon Dots-Decorated Bi2WO6 in an Inverse Opal Film as a Photoanode for Photoelectrochemical Solar Energy Conversion under Visible-Light Irradiation

“…A xenon lamp was used as solar light simulator and the light intensity was adjusted to 100 mW·cm −2 . Potentials were referenced to the reversible hydrogen electrode standard using the following formula [50]:ERHE=Evs.(Ag/AgCl)+Eref(Ag/AgCl)+0.059PH where E ref(Ag/AgCl) = 0.209 V vs. NHE at 25 °C.…”

Incidence Dependency of Photonic Crystal Substrate and Its Application on Solar Energy Conversion: Ag2S Sensitized WO3 in FTO Photonic Crystal Film

“…Photocatalysis for applications on a photon-electricity or photon-chemical bond have been paid much attention due to the energy crisis and environmental pollution [1]. Photoelectrochemical devices were therefore developed to perform solar energy conversion including photocurrent generation [2], pollutant degradation [3], and H 2 or CO evolution [4,5]. In consideration of the photocatalysis mechanism, improving the performance of a solar energy conversion device is based on several critical factors, such as the enhancement of light harvesting, efficient utilization of photons, rapid charge carrier separation and transportation.…”

Optimized Overall Photoactivity of WO3: Utilization of Incidence Dependence from Photonic Crystal Substrate

“…Due to the increasingly serious environmental pollution and energy crisis, photo‐electricity conversion system received more and more attention, in which photo‐anode plays a crucial role in such application . As a part of photoelectrochemical system for the utilizing of solar energy, the performance of photoanode is reliant on light absorption, charge carriers separation and electrolyte/product diffusion . To this end, attempts such as doping or morphology controlling, adding co‐catalysts, designing composite materials have been made, and optimized photoactivity are therefore achieved.…”
