The metamaterial absorber intends the structure of the solar cell to boost its internal parameters like the short-circuit current density (Jsc), Voc and efficiency. In this work, A novel single band polarization insensitive metamaterial (MTM) absorber is designed and investigated for solar cell energy harvesting applications. The proposed MTM unit cell is made of three layers named as glass bottom layer, layer 1, layer 2 and a top metal conducting layer. All these layers are stacked on a glass substrate with a thickness of 2.5 nm. The proposed MTM unit cell and its variations makes it possible to have a higher absorption rate of greater than 75% across the full range of visible spectrum. By analyzing the unit cell, it was found that it delivers a tunable character and maximum absorption of >75% over a wide range of frequency (534–672 THz) in the visible regime. The parametric study of overall size of the MTM absorber was analyzed over the frequency range from 450 to 750 THz. This design responds to a near perfect absorption of 99.99% at a resonance frequency of 560–570 THz and also has >90% absorption between 570 and 650 THz frequencies which is almost half of the visible range. Based on the similar works in the existing literature it has been found that the proposed MTM unit cell design was found out to be the best for high-efficiency solar cell energy harvesting applications.
