As the climate crisis looms, scientists are racing to find solutions to common clean energy problems, including solar energy storage. Solar energy is one of the best renewable resources we have, but it has challenges that prevent it from being widely adopted and replacing conventional energy sources. Because solar energy is variable throughout the day and throughout the year, it is important to have a robust storage system. Currently, solar is converted to electricity in solar cells, which cannot store the energy long-term, and separate battery storage systems are inconvenient and expensive. To solve this problem, researchers are trying to find ways to combine the power conversion and storage capacity needs of solar energy into one device.
