Energy harvesting from energy sources is a rapidly developing cost-effective and sustainable technique for powering low-energy consumption devices such as wireless sensor networks, RFID, IoT devices, and wearable electronics. Although these devices consume very low average power, they require peak power bursts during the collection and transmission of data.
The renewable energy sources like solar and wind energy are very clean and abundant. However, it is difficult to grab optimal power from these power sources due to the unpredictable operating conditions. The Hybrid Super Capacitor (HSC) has been classified as one of the Asymmetric Super Capacitor''s specialized classes (ASSC) [35]. HSC

As a result, supercapacitors are gradually transforming from being mere components in energy systems to becoming integral elements in the future of renewable energy. Solar Energy Harvesting and Storage: Lithium-Ion Batteries vs. Supercapacitors. In the realm of solar energy systems, the process of energy harvesting and storage plays a pivotal role.
In addition to commercial PV technologies, researchers have focused on developing novel methods for solar energy harvesting, such as silicon nanowire solar cells [161, 162], dye-sensitized solar cells [163, 164], quantum dot solar cells [165], perovskite solar cell [166], and so on.

Supercapacitors A supercapacitor, also known as an ultracapacitor or electric double-layer capacitor (EDLC), is an energy storage device that bridges the gap between conventional capacitors and batteries. Unlike batteries, which store energy chemically, supercapacitors store energy electrostatically. This enables rapid charging, making them ideal for applications
