Quantum Effiency of Tigan/Gan Quantum Dot Sollar Cells with Varying of Environment Temperature

Abstract

This work deals with thallium-based quantum dot solar cells. The structures studied are TlGaN/GaN Structure. The parameters such as energy sub bands, absorption, and quantum efficiency (QE) spectra studied for different temperatures. Found that the absorption intensity and QE were increased with increase of the Our environment Temperature 260,270,300,320,340 K respectively   . In addition, QE was decreased with increasing the junction depth for the structures; the proposed solar cells are covering the ultra violet and part of visible   range 380-440nm, which have important applications especially in solar cells.
