Supercapacitors (SCs) are those elite classes of electrochemical energy storage (EES) systems, which have the ability to solve the future energy crisis and reduce the pollution [ 1–10 ]. Rapid depletion of crude oil, natural gas, and coal enforced the scientists to think about alternating renewable energy sources.
However, supercapacitors lack in energy density compared to batteries; thus, it is often used as a short-term energy storage device. Supercapacitors are generally divided into three groups: a) electric double-layer capacitor (EDLC), b) pseudocapacitor, and c) hybrid supercapacitor.
These integrated systems consist of energy conversion devices, such as solar cells, and energy storage devices, including batteries and supercapacitors. For the successful operation of this integrated system for energy harvesting, conversion, and storage, it is essential to have high-efficiency photovoltaic devices like PSC [ 42 ].
