Tailoring of Bandgap to Tune the Optical Properties of GaAlY (Y = As, Sb) for Solar Cell Applications by Density Functional Theory Approach.
The bandgap was tuned to investigate the electronic and optical aspects using first-principle calculations for solar cells and other optical applications. The bandgap range varies from 1.6 to 2.1 eV for GaAlAs and from 0.8 to 1.5 eV for GaAlSb (x = 0.0, 0.25, 0.5, 0.75, 1.0). The dispersion, polaris...

The bandgap range varies from 1.6 to 2.1 eV for GaAlAs and from 0.8 to 1.5 eV for GaAlSb (x = 0.0, 0.25, 0.5, 0.75, 1.0). The dispersion, polarisation, and attenuation have been illustrated in terms of transparency and maximum absorption of light. The inversion of polarised atomic planes near the resonance allows the maximum absorption in ultraviolet to visible region. The Penn's model (ε(0) ≈ 1 + (ℏω/E)) and optical relation ε 1 (0) ${\varepsilon_{1}}\left(0\right)$ = n(0) confirm the reliability of our finding. The maximum absorption, optical conduction, and minimum optical energy loss increase the credibility of the studied materials for energy storage device manufacture. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2019 holdings: @attributes: islocal: N |
