Researchers in Barcelona have developed an innovative hybrid device that is a vital step toward a cleaner and more efficient energy future. It revolutionizes how we capture and store solar energy, given its intermittent nature. The device combines molecular solar thermal energy storage and traditional silicon-based photovoltaic energy for the first time. The device combines a silicon solar cell with a storage system called MOST that uses common elements such as carbon, hydrogen, oxygen and nitrogen. In practical tests, the device has achieved a record-setting energy storage efficiency of 2.3%. It is able to further increase efficiency by lowering the temperature of photovoltaic cells. Effectively combining these two systems ensures a more reliable energy output and lessens the environmental impact of traditional energy storage methods.
