Silicon Nanowire Photocathodes for Photoelectrochemical Hydrogen Production
The performance of silicon for water oxidation and hydrogen production can be improved by exploiting the antireflective properties of nanostructured silicon substrates. In this work, silicon nanowires were fabricated by metal-assisted electroless etching of silicon. An enhanced photocurrent density of -17 mA/cm² was observed for the silicon nanowires coated with an iron sulphur carbonyl catalys...
متن کاملQuantum dot-doped porous silicon metal–semiconductor metal photodetector
In this paper, we report on the enhancement of spectral photoresponsivity of porous silicon metal-semiconductor metal (PS-MSM) photodetector embedded with colloidal quantum dots (QDs) inside the pore layer. The detection efficiency of QDs/PS hybrid-MSM photodetector was enhanced by five times larger than that of the undoped PS-MSM photodetector. The bandgap alignment between PS (approximately 1...
متن کاملPHOTOELECTROCHEMICAL PRODUCTION of HYDROGEN
In this year’s Phase II photoelectrochemical hydrogen production research at the University of Hawaii, we have continued our emphasis on developing high-performance multi-junction hydrogen photoelectrodes based on low cost semiconductor and catalyst films. Significant progress was made in the advancement of amorphous silicon/germanium and copper indium gallium diselenide materials for solid-sta...
متن کاملPhotoelectrochemical Hydrogen Production
At the University of Hawaii (UH), the approach to developing high-efficiency, low-cost photoelectrochemical (PEC) processes for the direct production of hydrogen has included the use of integrated electrochemical/optical models to design photoelectrodes based on multijunction thin-film technology; materials research to identify critical issues on photoelectrode efficiency and stability; and the...
متن کاملPhotoelectrochemical Systems for Hydrogen Production
Two important research areas that are part of NREL’s effort towards a photoelectrochemicalbased (PEC) direct water splitting system include surface modification to improve system energetics and triple junction amorphous silicon structures (α-Si) as a low-cost thin-film water spitting system. In the area of surface modification, p-GaInP2 surfaces were tailored by adsorption of metallated porphyr...
