This book covers the physical principles and applications of a range of nanoscale materials and devices that are key for the energy revolution, including hybrid and organic solar cells, lithium batteries, and supercapacitors. Topics discussed range from the fundamental concepts of operating nanoscale energy devices to advanced device modeling. Modeling is presented as a function of the characterization techniques used to test device properties, emphasizing impedance spectroscopy characteristics, since it provides a unifying theme that connects the properties of the different energy devices.
