Technology and R&D

Scientists at the Royal Melbourne Institute of Technology (RMIT) have demonstrated the first working example of a “proton battery”, which utilizes a carbon electrode and a reversible hydrogen fuel cell for the storage of energy. The scientists say their small prototype has already demonstrated similar storage capacities to commercially available lithium-ion batteries, with plenty of potential for further optimization.

A team of scientists based at the Jiangsu Key Laboratory for Carbon-Based Functional Materials and Devices has integrated a silicon solar cell with a device that generates power from the motion of raindrops, an innovation which could greatly enhance performance in cloudier climates.

Researchers in the U.S. have confirmed the existence of a novel state of the element manganese, first proposed in a journal dating from 1928, which could allow for the development of low-cost, high performance batteries for grid level and other energy storage applications.

A team of scientists based at New York University (NYU)’s Tandon School of Engineering has developed a method of improving the performance of non-fullerene organic solar cells, by introducing a crystallizing agent.

Scientists led by the University of Braunschweig have developed a new type of solar concentrator, which can concentrate light from any direction onto a small area, such as a solar panel. The researchers say that funnels can be tuned to different light wavelengths and stacked, allowing for conversion of the entire light spectrum into electricity.

A team led by Chonnam National University in South Korea has developed a new perovskite solar cell composition, which it says could lead the way to the production of “highly efficient and air stable perovskite solar cells”.

Just one month after announcing a PERC module efficiency of 20.41%, the Chinese solar manufacturer announced it has now achieved a 23.6% efficiency for its PERC monocrystalline cells, thus beating its own previous records.

As Energy Storage Europe approaches, pv magazine counts down the highest-ranked energy storage highlights, selected by our independent jury, that visitors to the exhibition can lay their eyes on. In fourth-place was Fraunhofer ISE’s Cell-Booster and the power electronics for the project “Netefficient”, a technology planned for higher efficiencies, while reducing construction volumes.

While they cannot match the durability and efficiency of inorganic silicon-based solar cells, organic polymer solar cells show potential to provide power to remote microwatt sensors, wearable technology and the Wi-Fi-connected devices constituting the Internet of Things.

The Topsector Energie scheme, which will also support all kinds of innovative energy projects, has a budget of €130 million for 2018.
