Textbook in PDF format The storage of solar energy is as important as its harvesting. So far, solar energy has been primarily stored using electrochemistry-based batteries. Generally, batteries that can be charged with solar energy serve domestic and portable systems, especially in devices with low energy use. In addition to classic devices, innovative devices have been developed in recent years that provide both the conversion and storage of solar energy. In the last few years, supercapacitors have gained significant recognition due to their low cost, safe operation, fast charge-discharge cycles, high power density, and cyclic stability. This book comprehensively covers both batteries that can be charged with solar energy and photo-supercapacitors. Through expert insights and real-world case studies, this book offers an in-depth look at these innovative technologies and how they are shaping a more sustainable future
