Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. The procedure was based on a dataset of more than 400,000 molecules, which the researchers screened to find the optimum molecular structure for solar energy storage materials.
