“…However, when the thickness of the absorber layer increased further, the series resistance of the cell rises at a low concentration below 10 15 cm −3 , causing the drop of FF to ∼75%. It was observed from figure 2(d) that the power conversion efficiency (PCE) exhibited a slight increase with increasing thickness, followed by a subsequent decline at a thickness of 1 μm [35]. Thus, the maximum efficiency η over 30% was achieved with V OC of 1.1 V, J SC of 31.06 mA cm −2 , and FF of 87.28% at a MoSe 2 absorber thickness of approximately 1.0 μm and doping concentration of 10 16 cm −3 with BSF layer (figure 2(d)).…”

In this study, molybdenum diselenide (MoSe2)-based dual-heterojunction with Indium Telluride (In2Te3) as an absorber and a back surface field (BSF) layers with Al/ITO/CdS/MoSe2/In2Te3/Ni heterostructure has been studied by SCAPS-1D simulator. To explore the potentiality of layered materials in photovoltaic devices, a detailed investigation has been executed on the CdS window, MoSe2 absorber, and In2Te3 BSF layers at varied layer thicknesses, carrier concentrations, interface and defect densities, resistances, and operating temperatures. The photoconversion efficiency (PCE) of 24.78% with short circuit current J sc of 30.55 mA cm−2, open circuit voltage V oc of 0.95 V, and fill factor FF of 85.5% were obtained in the reference cell (without the In2Te3 BSF layer), while a notably improved PCE of 29.94% (5.16% higher) with J sc of 31.06 mA cm−2, V oc of 1.10 V, and FF of 87.28% was achieved by inserting the In2Te3 BSF layer. With a favorable band alignment and almost similar chemical and physical properties as transitional metal dichalcogenides (TMDCs) materials, the proposed dual heterostructure with CdS, MoSe2, and In2Te3 exhibits huge potential as a photoactive material and paves a pathway for the fabrication of uniquely layered material-based thin, flexible high-efficiency solar cells.

“…This is why the best choice is to build a tunnel intersection with a high impurity concentration [20]. The temperature has a great effect on the performance of the cell if the tunnel junction has lower doping [21], [22], and [23]. Increasing the bandgap of the junction will improve the performance of the cell [24].…”

The dual junction (tandem) cell structure (InGaP/GaAs) is depending on Indium gallium Phosphides (InGaP) as the upper cell, Gallium Arsenide (GaAs) as the lower cell, and behaves as tunnel junction (TJ). The structure of the (InGaP/GaAs) dual junction cell was simulated in this work using SILVACO program to obtain a high solar cell efficiency. Firstly, the effect of doping concentration and thickness of window layer of the upper cell was investigated on the (InGaP/GaAs) tandem cell performance. Then the GaAs /GaAs (TJ) is replaced by an InGaP/GaAs (TJ).A comparison of performance parameters between the two types of tunnel diode (GaAs / GaAs) and (InGaP/GaAs) was studied. The parameters that have been compared are open-circuit voltage (VOC), efficiency (η), the short circuit current density (JSC), and Fill Factor (FF). Quite high operating factors for tandem cell are achieved by taking into account the crucial number of cells as well as improving layer parameters of the layers. All calculations and simulations of tandem cell are performed with the typical AM1.5 solar spectrum light intensity of 1-sun at room temperature (300 K). Lastly, the findings illustrate that the optimum properties of the suggested tandem cell are efficiency (η) = 34.37 percent, VOC = 2.449 V, JSC = 21.69 mA/cm 2 , FF=89.33 percent.

“…In the past decade, tremendous progress has been made in incorporating the perovskite material as the absorber layer in solar cells, and the performance efficiency has improved to 26.1% in 2022. − The popular perovskite light absorber materials such as formamidinium lead iodide (FAPbI 3 ) and methylammonium lead iodide (MAPbI 3 ) contain toxic lead and hence are not environmentally and biologically compatible when employed in perovskite solar cells (PSCs) as light absorbing materials. − It has been proved experimentally that the highest achieved efficiency for PSCs corresponds to the device with the MA + cation containing perovskite as the absorber material . The inherent volatile nature of the perovskites with the organic MA + cation affects the efficiency and the performance of the perovskite solar cells with the MA + cation containing perovskite as the absorber material .…”

The single, double absorbers-based perovskite solar cells (PSCs) have attracted considerable attention of researchers in the past few years due to their promising photovoltaic parameters. The present work discusses a comparative performance analysis of the two configurations, namely the ITO/C60/MAPb(I1–x Cl x )3/CuSCN/Au, ITO/C60/MAPbI3/CuSCN/Au, and ITO/C60/MAPb(I1–x Cl x )3/MAPbI3/CuSCN/Au composed of a single layer of perovskite as the absorber and a double layer of two different halide perovskites as absorber materials, respectively. The MAPb(I1–x Cl x )3-based PSCs provide lower performance parameters when compared with the performance of MAPbI3-based PSCs and limit their output for photovoltaic applications. Nevertheless, the need to find maximum absorbance due to the novel grading approach leads to absorbing a wider quantity of light spectra, boosting efficiency. SCAPS-1D, as a software simulator, is used to examine our proposed models. The optimal output parameters obtained in this simulation are J SC of 21.41 mA/cm3, V OC of 1.278 V, FF of about 88.03%, and PCE of 24.10%, respectively.
