A Swiss research team has succeeded in increasing the efficiency of perovskite silicon tandem solar cells to over 30 percent. This is a world record.

MIT engineers have developed ultra-light fabric solar cells that can quickly and easily turn any surface into a power source.

Dust accumulating on solar panels is a big problem. But washing the panels consumes large amounts of water. MIT engineers have now developed a waterless cleaning method.

The sun is likely to become the world's most important source of energy before 2050, according to British scientists. This is the result of an analysis of technological and economic data by the University of Exeter and University College London.

The solar cells from the inkjet printer are ultra-thin and flexible - and should also work inside buildings.

Whether for smartphone screens or solar cells: Precious metals such as iridium or ruthenium are in high demand. Researchers from Basel have developed a cheaper and less toxic alternative.

Researchers have come up with the vision of a pumped storage power plant of a special kind. Their idea involves a type of cable car that can be used to transport sand or gravel up mountains in order to generate electricity when required by transporting it down the mountain again.

Never before have flexible solar cells been so efficient: A team from the Swiss Federal Laboratories for Materials Science and Technology (Empa) has created a flexible thin-film solar cell with a record-breaking efficiency of 20.8 percent.

Scientists in Singapore have developed a low-cost device that can harness the energy of light breezes and store it as electricity.

At high altitudes the wind is much stronger. Empa researchers want to harness the energy slumbering in the wind with the aid of kites. The technology would be particularly suitable for generating electricity in remote areas.
