Abstract—This paper reports a study on the effect of series resistance and layer thickness on the performance of an perovskite photovoltaic cell which is based on active layer of Molebdenum tri Oxide(MoO3) and Methyl ester(PC60bm). Electrical simulation has been examined on FTO: MoO3: perovskite layer : PC60bm -Au structure with GPVDM (General Purpose Photovoltaic Device Model) software. We used the GPVDM software to investigate the effect of series resistance and layer thickness on power conversion efficiency (PCE) and fill factor (FF) in an perovskite solar cell which is based on MoO3: PC60bm as an absorbing layer. The changes were made by applying the different series resistance and layer thickness value. The results show that the power conversion efficiency can be increased by changing the value of the series resistance and layer thickness, in our case the power conversion efficiency has been increased from 16.66% to 20.42% and fill factor has been change from 66.29% to 71.22%.
and PCBM (phynyl-C-70buteric acid methyl ester) [1-2]. Gpvdm (OPVDM's new name) is a free general-purpose device,This type of cell gives low value of PCE. Originally designed to simulate organic solar cells, it has now been expanded to simulate other system categories, including OLEDs, OFETs and many other forms of solar cells of 1st, 2nd and 3rd generation. The 4th generation is based on perovskite physical model solves drift-diffusion of electron and hole as well as continuity equations of the carrier in position space to describe the load movement within the device. The model facilitates the study of the effect on system performance of product parameters such as mobility, energetic disorder, doping, and recombination crosssections. All internal device parameters such as current density load frequency, position distribution of trapped carriers and energy storage can be controlled through either the graphical interface or directly from output data. The system includes both an electrical and an optical solver, allowing simulation of current / voltage characteristics and the optical model profile within the device. The model is available for Windows and Linux (x86 and ARM) and it is easy to use graphical interface. Gpvdm is a tool used to simulate and design solar cells to harvest the energy of the sun.
Keywords—Perovskite photovoltaic cell, MoO3: PC60bm, GPVDM, series resistance, thickness effect. 1.INTRODUCTION Perovskite photovoltaics (PPVs) have attracted considerable interest over the past two decades due to their advantages over organic solar cells. PPVs are lightweight, cheap and non-toxic compared to organic solar cells. They are also robust and versatile mechanically. Perovskite solar cells, as the name implies, transform light from oxide molecules into electricity. For these solar cells, Oxide and Methyl ester molecules are widely used. Their long chain relocation via alternating double and single connections helps to effectively transfer the electron in the cell. The highest occupied molecular orbitals (HOMOs) and the lowest unoccupied molecular orbitals (LUMOs) are these orbits. An optical band gap in the half conductor area is the power disparity between the low-energy HOMOs and the highenergy LUMOs. Because of their versatile material properties and low-cost processing, Perovskite cells have been a very remarkable area of research in recent years.

In the early 2000s, Perovskite solar photovoltaic cells were developed. Since 2009, organic chemistry has had a fast growth and the first discovery of photoconductivity in organic compounds was published in 1906. The product, Solarmer, developed for the first time Organic Photovoltaic. BHJ-based organic solar cells (Bulk Hetrojunction) are composites of P3HT (Poly3-hexylthiophene) © 2022, IRJET

The significant parameters that influence its performance should be explored in order to improve the power conversion efficiency of pervoskite solar cells. The GPVDM software simulates the organic solar cell at various layer thicknesses. This model consists of both electrical and optical properties and is specifically designed to mimic
