“…An efficiency of 19.75% for the ZnO: Al/i-ZnO/CdS/CIGS system was reached. In one study [30], a CIGS solar cell was prepared using a vacuum deposition technique. A power conversion efficiency of 4.3% was obtained when cupric selenide nanoparticles were present, while a significantly lower efficiency was observed in the absence of these nanoparticles.…”

This study presents the numerical simulation, optimization, preparation, and characterization of Cu(In, Ga)Se2 (CIGS) thin-film solar cells (TFSCs). Different cell parameters were investigated, including Ga/(Ga+In) (GGI) ratios, the thicknesses of CIGS absorption layers, the fill factor (FF), the open-circuit voltage (Voc), and the short-circuit current (Isc). The effects of the simulated parameters on the power conversion efficiency (η) of each prototype CIGS cells were investigated. The optimal GGI ratio was approximately 0.6. Using COMSOL Multiphysics software, a CIGS layer thickness of 2 μm and an η of 17% was calculated, assuming constant operating temperatures. Moreover, prototype CIGS solar cells with various compositions were prepared via a simple and cost-effective method based on sol–gel, sonication, and spin-coating techniques. The microstructures and electrical and optical properties of the CIGS-based solar cells were evaluated using current–voltage (I-V) characteristics, scanning electron microscopy (SEM), X-ray diffraction, atomic force microscopy (AFM), and UV-vis spectroscopy. The elemental compositions of the solar cell layers were evaluated via energy-dispersive X-ray fluorescence (EDXRF). The obtained results were compared with the experimental results. For example, in a prototype cell with a CIGS absorption layer thickness of 2 μm and a GGI ratio of 0.6, the experimental value of η was about 15%. Our results revealed that the agreement between the simulation results and the experimental findings for most of the simulated parameters is quite good. These findings indicate that a non-destructive analysis based on EDXRF is a versatile tool for evaluating CIGS solar cells in a very short time with excellent repeatability for both layer composition and thickness.

“…Although silicon dioxide is abundantly available in nature in the form of silicon dioxide, making it able to be used as a PV material requires a great amount of energy [3]. Other materials such as a-Si [4], CdTe [5], GaAs [6], CIGS [7], perovskite, and organic [8] based solar cells also exhibit high e ciencies but have some drawbacks in terms of high manufacturing cost, toxic nature, low thermal and chemical stability and low outdoor life [9,10]. To overcome or eliminate the problems associated with existing materials, searching for new potential materials would be a viable option.…”

Carbon nitride (C2N) based solar cell is getting cynosure in the photovoltaic research community due to their tremendous advantages over other thin-film solar cells such as environmentally friendly material nature and low fabrication cost. In this paper, we theoretically analyzed Zinc Magnesium oxide (Zn1 − xMgxO) as a buffer layer coupled with C2N as an absorber layer to form a p-n junction by using SCAPS- 1D simulation tool. ZMO as an electron transport layer (ETL) utilized with four Mg (x) doped with the concentrations of x = 0.0625, 0.125, 0.1875, and 0.25. After optimizing different layers for the proposed structure, it has been noticed that increasing the thickness of the C2N layer results in the enhancement of efficiency rate. Further, it was observed that the doping density of C2N beyond 1015 cm− 3 degrade the performance of the cell. In addition to this, the optimization of the buffer layer is performed and the optimum performance parameters were achieved at 30 nm. The theoretically modelled structure shows a great enhancement in Open circuit voltage (Voc), Short circuit density (Jsc), Fill factor (FF), and Power conversion efficiency (PCE) with regards to the presented approach. The structure is compared with different kind of other solar cells and obtained parameters shows the higher values of Voc of 1.225 V, Jsc of 18.2572 mA/cm2, FF of 84.96%, and PCE of 19.01%. The recorded results are in good agreement with the standard theoretical studies.

“…Solar energy with its unlimited quantity is expected to be one of the most promising alternative energy sources in the future [ 4 , 5 , 6 ]. Various solar energy devices have been widely utilized for photovoltaic (PV) applications; these include silicon [ 7 , 8 , 9 ], copper indium gallium selenium [ 10 , 11 , 12 ], cadmium telluride [ 13 , 14 ], concentrating PV [ 15 , 16 , 17 ], and organic solar cells such as dye sensitized solar cells [ 18 , 19 ]. Innovation that includes multiple excitonic concepts, band gap engineering, introduction of quantum dots and nanotechnology particles having higher efficiencies is growing in scientific research and in laboratory scale production to improve the absorption level and maximize the efficiency of these solar cells [ 20 , 21 ].…”

Density Functional Theory Study of Optical and Electronic Properties of (TiO2)n=5,8,68 Clusters for Application in Solar Cells

A range of solution-processed organic and hybrid organic−inorganic solar cells, such as dye-sensitized and bulk heterojunction organic solar cells have been intensely developed recently. TiO2 is widely employed as electron transporting material in nanostructured TiO2 perovskite-sensitized solar cells and semiconductor in dye-sensitized solar cells. Understanding the optical and electronic mechanisms that govern charge separation, transport and recombination in these devices will enhance their current conversion efficiencies under illumination to sunlight. In this work, density functional theory with Perdew-Burke Ernzerhof (PBE) functional approach was used to explore the optical and electronic properties of three modeled TiO2 brookite clusters, (TiO2)n=5,8,68. The simulated optical absorption spectra for (TiO2)5 and (TiO2)8 clusters show excitation around 200–400 nm, with (TiO2)8 cluster showing higher absorbance than the corresponding (TiO2)5 cluster. The density of states and the projected density of states of the clusters were computed using Grid-base Projector Augmented Wave (GPAW) and PBE exchange correlation functional in a bid to further understand their electronic structure. The density of states spectra reveal surface valence and conduction bands separated by a band gap of 1.10, 2.31, and 1.37 eV for (TiO2)5, (TiO2)8, and (TiO2)68 clusters, respectively. Adsorption of croconate dyes onto the cluster shifted the absorption peaks to higher wavelengths.
