First principles study on structural and electronic properties of hexagonal CdSe for improved efficiency of solar panel
DFT, SIESTA, electronic band gap.
Cadmium Selenide (CdSe) in hexagonal structure investigated by First Principles study with local density approximation (LDA) and generalized gradient approximation (GGA) using the SIESTA code for their structural and electronic properties. A hexagonal CdSe structure with bond length of 2.69 Å and bond angle of 109.36º was found. For calculation, electronic properties of hexagonal CdSe are obtained by k-point sampling and cut off energy, then DOS, PDOS and band structures are obtained. Results indicate different band gap values for the compounds, and the calculated values are underestimated. According to DOS calculation energy gap between the valance and the conduction band is 1.29eV same as PDOS calculation, founded smaller then experimental band gap value 1.74 eV, and it is direct band gap nature. As the band gap decreases, the efficiency of the CdSe thin films used in solar cells increases.
