Electrochemical energy storage in photovoltaic plants

A photovoltaic (PV) plant is not itself an electrochemical energy storage system, but it often utilizes electrochemical storage technologies, such as batteries, to store energy generated from sunlight. Electrochemical storage is commonly coupled with PV plants to manage energy supply and demand effectively2. Thus, while PV plants generate electricity, they rely on electrochemical storage systems to store that energy for later use. As the energy crisis and environmental pollution problems intensify, the deployment of renewable energy in various countries is accelerated. Solar energy, as one of the oldest energy resources on earth, has the advantages of being easily accessible, eco-friendly, and highly efficient [1].Moreover, it is now widely used in solar thermal utilization and PV power generation.
