Semitransparent organic solar cells in eyeglasses to power microprocessor, example of future solar-powered mobile applications. Organic solar cells are flexible, transparent, and light-weight – and can be manufactured in arbitrary shapes or colors. Thus, they are suitable for a variety of applications that cannot be realized with conventional silicon solar cells. In the Energy Technology journal, researchers from KIT now present sunglasses with colored, semitransparent solar cells applied onto lenses that supply a microprocessor and two displays with electric power...

Graphene-based electrode prototype, inspired by fern leaves, could be the answer to solar energy storage challenge. Inspired by an American fern, researchers have developed a groundbreaking prototype that could be the answer to the storage challenge still holding solar back as a total energy solution. The new type of electrode created by researchers from RMIT University in Melbourne, Australia, could boost the capacity of existing integrable storage technologies by 3000%.

But the graphene-based prototype also opens a new path to the development of flexible ...

“Our research team has developed a simple and cost-effective fabrication technique to create solar absorbers that can harness a greater share of the solar spectrum, thus increasing their efficiencies, while also maintaining low emission levels,” said Masdar Institute’s Dr. TieJun Zhang, Assistant Professor of Mechanical and Materials Engineering.

New approach for storage of concentrated solar thermal energy has been found, to reduce cost and make it more practical for wider use. The advance is based on thermochemical storage, in which chemical transformation is used in repeated cycles to hold heat, use it to drive turbines, and then be re-heated to continue the cycle. Most commonly this might be done over a 24 hour period, with variable levels of solar-powered electricity available at any time of day, as dictated by demand.

Conceptually, all of the energy produced could be stored indefinitely and used later when the electricity is...
