Summary:

- This article discusses a new type of rechargeable "liquid solar battery" that can store energy from sunlight in the form of chemical bonds within molecules.
- The battery uses a light-sensitive organic compound that can undergo reversible chemical reactions when exposed to sunlight, allowing it to store and release energy on demand.
- This technology has the potential to provide a more efficient and cost-effective way to store solar energy compared to traditional batteries, which could be useful for applications such as renewable energy storage and powering portable devices.
