Design of Solar Power Propagation using Silicon Nanowire Photonic Crystals for Electric Vehicles

Photonic crystals are materials for controlling and manipulating the light flow. Nano photonic devices deal with behavior of the light in the nanomaterial and devices. It works on the interaction of nano devices with light. They are periodic structures with different refractive indices. The wave guides can be constructed will have sharp and low-loss bending enabling high integration density of several orders of magnitude. On silicon surfaces, nano- and microstructures are created to lower reflection and increase light absorption. It can be applied to enhance infrared (IR) bolometer applications based on MEMS. In this work Silicon nanowires photonic crystals are grown and the electric characteristics and frequency characteristics are modeled, simulated and studied using finite element method. Waveguide is created by removing a set of wires making a path for signal flow for the frequency within the band gap. It is observed that depending on the displacements of the nanowires, waves of particular frequency range is getting reflected which is photonic band gap. The infrared response of silicon nanowires for the IR range (2.5 - 20m), the broadband infrared absorption is found to be boosted by around 2.5 to 3 times when compared to that of polished silicon. The Si nanowires IR sensitivity offers exciting prospective uses as a wideband IR absorbing/sensing mate.
