Abstract

In recent years, quantum dot solar cells have attracted attention due to their versatile electrical and optical properties as a material. A quantum dot solar cell can be tuned in terms of bandgap and size. In this work, the effect of defect density on the performance of a solar cell is studied with the help of the Solar Cell Capacitance Simulator in One Dimension (SCAPS-1D) software. The defect densities of poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA)/lead sulfide (PbS)–tetrabutylammonium iodide (TBAI) and lead sulfide–TBAI/titanium dioxide (TiO2) are varied from 1 × 1010 to 1 × 1017 cm−2, and the electron mobility of titanium dioxide, temperature and work function are also varied. These simulation-based quantum dot absorber-based solar cells may, in the future, prove to be extremely effective quantum dot solar cells.
