摘要
As the performance of photoanodes for solar water splitting steadily improves, the extension of the absorption wavelength in the photoanodes is highly necessary to substantially improve the water splitting. We use a luminescent back reflector (LBR) capable of photon upconversion (UC) to improve the light harvesting capabilities of Mo:BiVO4 photoelectrodes. The LBR is prepared by dispersing the organic dye pair meso-tetraphenyltetrabenzoporphine palladium and perylene capable of triplet-triplet annhilation-based UC in a polymer film. The LBR converts the wavelengths of 600-650nm corresponding to the sub-band gap of Mo:BiVO4 and the wavelengths of 350-450nm that are not sufficiently absorbed in Mo:BiVO4 to a wavelength that can be absorbed by a Mo:BiVO4 photoelectrode. The LBR improves the water splitting reaction of Mo:BiVO4 photoelectrodes by 17%, and consequently, the Mo:BiVO4/LBR exhibits a photocurrent density of 5.25mAcm(-2) at 1.23V versus the reversible hydrogen electrode. The Mo:BiVO4/LBR exhibits hydrogen/oxygen evolution corresponding to the increased photocurrent density and long-term operational stability for the water splitting reaction.
