    Due to increase in demand for energy storage in today’s society, the development of inexpensive, flexible and light weight energy storage device is essential. In this respect, paper-based energy storage devices are highly being preferred. The aim of this thesis to evaluate the use of Banana, Papaya and Q2 source. Banana, Papaya and Q2 source are used for paper-based energy storage devices. We report the band gap and dielectric properties of indigenously collected natural fibers, by having the sources of Banana, Papaya and Q2 source. By making the sheets of the sources with 0%, 15%, 30% and 45% bleaching. Afterwards, their characterization Impedance, bending effect, energy storage capacity, dielectric properties are observed by having the equal weight of the entire sheets. Dielectric properties increased when we increased the fiber content because the no. of polar groups increased. Di-electric constant, dissipation factor, di-electric loss factor of natural fibers was high at low frequency. Di-electric values decreased when frequency increased for all hybrid composites. Photonic band gap fibers are similar to electron wave motion which is analyzed by Bloch formulation. Effect of design parameters are also observed in terms of variations of allowed and forbidden bands of band gap fibers. I concluded that banana is the best source in terms of flexibility for energy storage applications.
