Do we have another option for high-density storage? The researchers are constantly trying to find an answer to this question. After the collection of the huge sum of solar energy, their storage is the basic concern.
Hence, the researchers at the RMIT University have created a prototype electrode made from graphene and designed based on the fractal structure of the fern leaf. The electrode harvests more solar energy and though the storage systems are flexible, thin, but they still store more high-capacity energy.
Solar-powered devices are being set up not only in the residential but also commercial areas looking at the high need for energy. Nowadays, either large bulky or smaller solar energy storage devices are available. The researchers from the RMIT University want to build this huge gap by developing a high-density solar storage inspired by the fractal pattern seen in at the microscopic level in the American fern leaf veins.
Looking at the densely packed veins in the sword fern leaf, the researchers have created an electrode based on the naturally efficient design to advance the solar energy storage processes at a nanoscale. These fractal mini structures help the electrode store energy more efficiently as well as in large quantity. The new electrode can be used in the wearable electronics, cars, and others due to their nanosize and capability. The researchers plan to combine this electrode with a supercapacitor to enhance its storage capacity. This capacity-laden supercapacitor would be reliable on a long-term basis and also store a high amount of energy.
The graphene is used to make the electrode in order to make it conductive, thin, and flexible. The basic aim of creating this thin solar cell is to harvest and store energy in something as small as a chip. Solar energy is the new clean-energy source being used all across the globe as it is considered to be a better source of energy than the conventional sources.
This prototype helps overcome the storage challenge without affecting the solar device’s performance. Now future lies in achieving a goal of solar powered and reliant electronics.
