And it releases energy on-demand. ☀
The team has tested its device, called the Molecular Solar Thermal system , by connecting it to a thermoelectric generator, demonstrating that it produces electricity.
The Chalmers University of Technology team has been working on its technology for more than a decade, and it believes it can be used for low-power electronics devices that require electricity on demand. The system was designed using specially-developed molecules of carbon, hydrogen, and nitrogen. When they are hit by sunlight, the atoms within the molecule are rearranged, turning them into an energy-rich isomer that's stored in liquid form. Impressively, the researchers say their system stores energy in this liquid form for up to 18 years. It is released using a special catalyst that returns the molecules to their original shape, releasing the energy as heat.
"The generator is an ultra-thin chip that could be integrated into electronics such as headphones, smart watches, and telephones," said researcher Zhihang Wang from the Chalmers University of Technology."So far, we have only generated small amounts of electricity, but the new results show that the concept really works. It looks very promising."
According to research leader Kasper Moth-Poulsen, Professor at the Department of Chemistry and Chemical Engineering at Chalmers, the MOST system"means that we can use solar energy to produce electricity regardless of weather, time of day, season, or geographical location. It is a closed system that can operate without causing carbon dioxide emissions.
