Numerical Simulation and Performance Characteristics of Solid-state Dye-sensitized Solar Cell using SCAPS 1D

Nirupma Yadav, Abhishek Kumar Gupta, Sarvesh Kumar Gupta, Omhari Dubey


In this research article, we studied the optimization and performance of a titanium oxide (TiO2) working electrode for the manufacture of solid-state dye sensitized solar cell (so-DSSC). The structure of solid-state dye sensitized solar cell used in current work is composed of FTO/TiO2/N719/PEDOT: PSS/Pt. The only variable for simulation is absorber layer. The computational simulation findings indicate that parameters of solid-state DSSC such as VOC, JSC, FF and PCE are highly affected by the absorber layer thickness. For the purposes of simulation, Solar Cell Capacitance Simulator (SCAPS: 1D) has been used. Also, effect of acceptor concentration of dye N719 and work function of front and back contact on VOC, JSC, FF and PCE was examined. In addition, short circuit current (JSC), open circuit voltage (VOC), fill factor (FF), and quantum efficiency (QE) factors are also investigated. Our findings demonstrate that the electrical properties of solid-state DSSC can be upgraded on increasing the thickness of the absorber layer.
