Considering the rising demand for Perovskite solar cells (PSCs) owing to their performance and cost, resolving problems such as interface hysteresis and instability resulting from trap states is essential to PSC economic sustainability. Passivation techniques have being actively developed by researchers to address these issues. In this work, we examine the effects of adding a MoS2 interface layer to the structure of a perovskite solar cell. Our study concentrates on important performance parameters, with and without the MoS2 interface layer, such as power conversion efficiency (PCE), fill factor (FF), short circuit current (Jsc), and open circuit voltage (Voc). Extensive simulations demonstrate our results' notable enhancements. More specifically, the PCE of the RbGeI3 based PSC increases from 15.63% to 17.20% with the inclusion of the MoS2 interface layer. Moreover, our investigation shows improvements in Jsc and FF. By offering a clearer knowledge of how interface layers, such MoS2, might be used to enhance PSC performance, this work fills a significant research need. We provide light on the potential of MoS2, clarify the mechanisms underlying these improvements, and provide insights into how these tactics could speed the development and improve the efficiency of Perovskite solar cells.

“…The simulation results are in the range of the theoretical values founded by other papers for a solar cell with CZTS and Zn(S, O) used as an absorbent layer and a buffer layer, respectively. [52,53] A highest efficiency value of 10.55% was simulated using SCAPS with an open-circuit voltage (V oc ) of 840 mV, short-circuit density ( J sc ) of 25.26 mA cm À2 , and FF of 49.49% for the CZTS-3 thin film. However, the solar cell with CZTS-1 shows greater efficiency of about 10.79% but with a minimum J sc ¼ 19.64 mA.…”

Nowadays, the compound Cu 2 ZnSnS 4 (CZTS) semiconductor shows great ability to be considered as an alternative of the CIGS thin film in solar cells. Despite the excellent environment stability and the higher power coefficient efficiency which is around 22.6% represented by CIGS [1] and the new updated recorded efficiency (23.4%) according to the NREL site showed by CIGS solar cell, [2] its potentials are limited by scarcity of indium (In) and gallium (Ga), the relatively high cost of In, and also the toxicity issue represented by this element. To solve these issues, it is necessary to search nontoxic and element-abundant light absorber materials. CZTS quaternary semiconductor is constituted by Earth-abundant (Cu:50, Zn:75, Sn:2.2, S:260 ppm) and environmentally benign elements and also the CZTS properties match well with CIGS ones. In fact, the kesterite-based chalcogenide CZTS has a direct bandgap E g ¼ 1.5 eV, which promotes the bandgap of the absorbent layer for high efficiency, an absorption coefficient greater than 10 4 cm À1 , and is characterized by p-type conductivity, which make them ideal among all the secondgeneration thin-film solar cells. [3,4] Moreover, the simulation calculation proves that the CZTS solar cell has theoretical limit power conversion efficiency over 30%. [5,6] Meanwhile, the experimental efficiency of CZTS kept increasing from 6.7% in 2008 [7] to 11.1% in 2012. [8] Wang et al. achieved the highest photovoltaic conversion efficiency of CZTS(Se), which is 12.6%, by exploiting the hydrazine-based approach. [9] In addition to that, reasonable efficiency and great quality were observed for CZTS thin films deposited by many methods, such as sputtering deposition, [10] pulsed laser deposition, [11] and thermal evaporation. [12] However, these techniques require high temperature, high vacuum, and sophisticated tools that may have toxic chemical elements, which have an impact on the fabrication cost of CZTS thin films of a solar cell. To balance the cost and the solar efficiency, several studies tried to elaborate CZTS thin films with low cost and easily synthetic routes. [13][14][15] Among these methods, sol-gel spin coating represents many advantages such as being nonvacuum, facile, low cost, environmentally friendly, and also suitable for large-scale fabrication. It is well known that the properties of thin films prepared with spin coating depend on various parameters. Several articles reported the deposition of CZTS with spin coating and investigated the effect of layer thickness, [15,16] speed of coating, [17] preheating environment, [18] and annealing temperature, [19] on the structural, optical, and electrical properties of CZTS thin films. One of the most important parts of the elaboration of CZTS thin films with spin coating is solution preparation. However, in this step, the type of solvent used has a great impact on the reaction involved, by influencing its nucleation and growth process, which varied the composition and structure of CZTS thin films and controlled the optical and e...

In this study, in order to calculate PV parameters of undoped and Ag-doped CuO thin film solar cells using the SCAPS-1D simulation program, the thickness value, energy band gaps and absorption coefficient spectral file for the undoped and Ag-doped CuO thin films produced experimentally were used as an input for simulation program [24,[35][36][37][38][39][40][41].

Copper (II) oxide (CuO) has attained significant attention from researchers because of its unique chemical and physical properties. Ag-doped CuO thin films have been produced on the soda glass substrate (SLG) by spin coating technique at different doping ratios. Structural, morphological, and optical properties of thin films produced depending on altered silver ratios have been examined through X-ray diffraction (XRD) spectroscopy, scanning electron microscopy (SEM), and UV-vis absorption spectroscopy, respectively. Band gaps of prepared undoped and 1% Ag-doped CuO thin films have been measured as 1.90eV and 1.63eV, respectively. Ag/undoped CuO and Ag-doped CuO/ZnO/AZO solar cells have been modelled, and their photovoltaic parameters have also been calculated using the SCAPS-1D simulation program. This work aims to investigate the photovoltaic parameters that would improve the efficiency of a solar cell. The effect of Ag atoms on the efficiency of CuO solar cells has been investigated depending on the acceptor density (Na), the interface defect density (Nt), and the operating temperature. Ag-doped CuO solar cells have shown the highest efficiency for Nt=1010 cm-3 and Na=6, 5x1016 cm-3 values. It has been well observed that as the operating temperature increases, the solar cells’ power conversion efficiency decreases. The highest charge generation rates in the undoped and Ag-doped solar cells have been determined as 1.49×1022 1/cm3.s and 1.51×1025 1/cm3.s, respectively. All the results, either theoretical or experimental, have been presented in this work and have been compared for a conclusion that has been made in detail.
