A 100x more effecient oxygen production in artificial photosynthesis

Fujitsu claims, the use some advanced materials is increasing the effeciency of production of oxygen in Artificial Photosynthesis using sunlight and water by nearly 100-fold. To artificially produce storable energy in the form of hydrogen and organic compounds requires extraction of reaction electrons from a photocatalyst material using light source and electrode that help in efficiently reacting with water or CO2. Earlier, semiconductor materials and relatively coarse-grained photocatalyst materials have been used in low-density rigid structures for the photo reactive electrodes where sunlight and water react. But the issue with that was the usable wavelengths of light in sunlight (visible light) fall in a narrow range and was difficult to achieve sufficient current flow from the chemical reaction. Fujitsu could change that by using a thin film technology. Fujitsu has improved the methods of forming thin films (nano particle deposition of electroceramics on flexible mounting sheets to create capacitors or other passive components). To develop a process technology for layering thin films on a substrate, Fujitsu' developers have used a nozzle to spray the photocatalyst-material particle that fragments the particle on a thin plate. The key features Fujitsu explains are as follows: 1. Fujitsu could expand usable wavelength of sunlight so that sunlight is very well ...
