Abstract
The electronic and optical properties of the WSeTe monolayer have already been evaluated at different hydrostatic pressures up to 9 GPa using a first principles simulation based on dft. At all pressures, the material is semi-conductive and the band gap narrows. The examination of optical functions demonstrates that the WSeTe monolayer's absorption increases significantly as we travel towards the violet region as well as conductivity, making it useful in solar cells. All optical qualities increase as a result of the applied pressure. We contend that the extraordinary photovoltaic properties of the WSeTe monolayer have many applications in optical devices.
