Researchers in Japan have discovered a new photocatalyst, Sn3O4, which facilitates the production of hydrogen fuel from water, using sunlight as an energy source.[/cite]10.1021/am500157u[/cite]
Inexpensive computers, cell phones and other systems that substitute flexible plastic for silicon chips may be one step closer to reality, thanks to new research. Scientists have made a new proposal for overcoming a major obstacle to the development of such plastic devices — the large amount of energy required to read stored information.
Environmentally compatible production methods for organic solar cells from novel materials are in the focus of “MatHero”. The new project aims at making organic photovoltaics competitive to their inorganic counterparts by enhancing the efficiency of organic solar cells, reducing their production costs and increasing their life-time.
