Simulation study of defect density on the performance of quantum dot solar cell with PTAA HTL layer using SCAPS-1D

Abstract

In recent years, the quantum dot solar cell has attracted attention due to its versatile electrical and optical properties as a material. The quantum dot solar cell can be tuned in terms of bandgap and size. In the present work effect of defect density on the performance of the solar cell is studied with the help of Solar Cell Capacitance Simulator in one dimension (SCAPS-1D). The defect density Poly[bis(4-phenyl) (2,4,6-trimethyl phenyl)amine] (PTAA)/ PbS- tetra-butyl ammonium iodide(PbS-TBAI) and PbS- tetra-butyl ammonium iodide(PbS-TBAI/ Titanium dioxide(TiO2) is varied from 1x1010 cm−2 to 1x1017 cm−2 and variation of electron mobility of TiO2, temperature and work function is done. This simulation-based quantum dot absorber-based solar cells may, in the future, prove to be extremely effective quantum dot solar cell.
