Abstract
Methylammonium lead triiodide perovskite solar cells have attracted huge research interest. Its optoelectronic properties are competing with those of silicon wafers. It is a hybrid absorber with a direct band gap of about 1.53 eV with good light-absorption capability appropriate for optoelectronic applications. A typical perovskite solar cell HTML layer rarely incorporates ZnO or Cu 2 O or TiO 2 nanoparticles to increase charge carrier transport. These ZnO, Cu 2 O, TiO 2 nanoparticles can be introduced into the HTM layer to modify its PSCs efficiency and performance. These nanoparticles are direct band gap binary semiconductors with a wide band gap energy range of 2.17 eV to 3.37 eV respectively which can lead to higher transport mobility and enhanced HTM nanostructured layer. In this paper, two model solar cell having a ITO/TiO 2 /CH 3 NH 3 PbI 3 /P3HT/Ag and ITO/TiO 2 /Ag:CH 3 NH 3 PbI 3 /P3HT/Ag structures were proposed, geometrically modelled and simulated using SCAPS-1D software. Their HTM layer (composed of P3HT) was doped with ZnO, Cu 2 O, and TiO 2 nanoparticles respectively to determine their influence on PCEs of this solar cells. It was revealed that starting from undoped P3HT layer all through the Cu 2 O, ZnO to TIO 2 doped layers, efficiency reduced from 13.123 % and 9.071% respectively; fill factor (FF) also reduced from 69.4% to 48.9 % for the doped CH3NH3PbI3 perovskite solar cell while efficiency of doped CH 3 NH 3 PbI 3 perovskite solar cell reduced from 13.033 % and 9.091%, the fill factor (FF) also reduced from 66.4% to 52.9 % respectively. It was noted that the solar cell employing P3HT undoped layer had the best performance and concluded that introducing nanoparticles onto P3HT layer has a negative impact on the performance of CH3NH3PbI3 perovskite solar cell.

Summary
Modern thin-film solar cells have reduced material consumption [2] and fabrication costs. Computer Simulation Technology (CST) is a 3D simulation software used to numerically calculate optical properties required for many applications that include plasmonic solar cells, electromagnet metamaterials and antennas when exposed to an electromagnetic field It is a 3D EM solver that solves Maxwell's equation in the time domain with Finite integration method (FIT) and frequency domain with the Finite element method (FEM) by incorporating FDTD and FDFD techniques. FEM available in CST software and it is used to calculate solutions to partial differential and integral Maxwell’s equations It is suitable for simulating irregular shaped geometrical models for optical devices as it provides information even of large dtime and frequency domains small elements in regions where fields may abruptly change. It can simulate larger elements in less important and unexpected electromagnet regions
