“…On the other hand, and oppositely to the top cell, the bottom single solar cell CZTSSe has lower Voc of 529 mV and higher Jsc of 36.98 mA/cm 2 because of its lower band gap energy, which allows absorption of low energy photons (longer wavelength) and leads to increase the photocurrent [30]. Which supports our choice of this type of solar cells compared to those of the CIGS thin film solar cells as reported in [31], to achieve high efficiency.…”

Numerical simulation of CZTS/CZTSSe tandem solar cells utilizing Silvaco-Atlas was investigated. Firstly, the performances of conventional CZTS/CdS/ZnO and CZTSSe/CdS/ZnO single solar cells with thicknesses for both absorber layers at 360 nm and 3 nm, respectively, were studied independently. A wide band gap CZTS thin-film cell and a narrow band gap CZTSSe-based cell present conversion efficiencies of 11.10% and 13.76% respectively. This agrees with experimental and simulation results previously published. Furthermore, a CZTS/CZTSe tandem cell configuration is identified keeping the identical material properties. A good conversion efficiency of 25.27% was obtained. Finally, the thickness of the CZTS adsorption layer of the top cell was optimized as a crucial factor to enhance the tandem performance. Optimal thickness coinciding to a highest efficiency of 26.05% is 420 nm. The output parameters obtained are, Jsc  28.46 mA/cm 2 , Voc  1.27 V and FF  71.83%. This suggested results may help in the future research and may lead to the fabrication of CZTSSe-based solar cells.

“…ZnO and Spiro-OMeTAD are selected as the ETL and the HTL, respectively, from the earlier works, which resulted in obtaining higher efficiency. The front contact electrode, i.e., ITO is used in CIGS-based SCs, and hence, it validates the feasibility of ITO with CIGS materials. − The working principle of SC (CIGS/CsSnI 3 ) is represented in Figure b. The absorption coefficient (α) is illustrated from SCAPS-1D software where we utilized the term α = A α ( h ν – E g ) 1/2 .…”

The widespread results of the explicit modeling technique for hybrid-perovskite-based solar cells under the illumination spectrum of AM 1.5G are illustrated in the present simulative work. The research specifically aims to improve the overall device efficiency by considering innovative double perovskite hybrid-absorber layers (ALs). The perovskite solar cells (PSCs) offer high efficiency with hybrid and lead-free material, i.e., copper indium gallium selenide (CIGS) as well as cesium tin iodide (CsSnI 3 ). The present study utilizes Spiro-OMeTAD and ZnO as the carrier transport layers; as the electron−hole transport layer is sandwiched with the PALs of CIGS and CsSnI 3 , it has precise bandgap values of 1.3 and 1.27 eV, respectively. Using doublegraded materials of CIGS/CsSnI 3 results in an optimized efficiency of up to 26.55%. The comprehensive investigation of thicknesses, bulk defect densities, and temperature dependency of the current device configurations are also investigated.

“…Copper indium gallium selenide (CIGS), belonging to the group I-III-VI, has emerged as a highly promising choice for thin-film SCs (TFSCs). This is primarily owing to its excellent conversion efficiency, which has recently surpassed 23% [10] [11] [12]. Additionally, CIGS exhibits remarkable stability, cost-effectiveness, and configurable band gap of roughly 1.01 -1.69 eV [13] [14].…”

Thin-film solar cells possess the distinct advantage of being cost-effective and relatively simple to manufacture. Nevertheless, it is of utmost importance to enhance their overall performance. In this research work, copper indium gallium selenide (CIGS)-based ultra-thin solar cell (SC) configuration (Ag/ZnO/ZnSe/CIGS/Si/Ni) has been designed and examined using SCAPS-1D. The numerical calculations revealed that this new design resulted in a substantial improvement in SC performance. This study explores the utilization of two absorber layers, CIGS and Si, both with a total of 2 μm thickness, to enhance device performance while reducing material costs, observing an increase in key SC parameters as the Si absorber layer thickness is increased, reaching a maximum efficiency of 29.13% when CIGS and Si thicknesses are set at 0.4 μm and 1.6 μm, respectively with doping absorber doping density of 10 14 cm −3 . Furthermore, we analyze the impact of variation in absorber and buffer layer thickness, as well as doping concentration, surface recombination velocity (SRV), electron affinity, series-shunt resistance, and temperature, on optimized CIGS SC parameters such as short-circuit current density (J SC ), open circuit voltage (V OC ), fill factor (FF), and power conversion efficiency (PCE). The findings yielded by the investigation offer significant elucidation regarding the fabrication of economically viable and highly efficient non-hazardous CIGS ultra-thin SC.
