“…For the absorber thickness less than 1.5 µm and carrier concentration above 10 18 cm −3 , the J sc raise with CuO thickness growing could be ascribed to the CuO charge collection length and hence the collection of electron hole pairs in the junction will be improved 43 . This indicates that the charge carriers will be split up and stored clearly with thickness increasing.…”

“…( 3 ) 37 . On the other hand the V oc value increase with thickness increasing and therefore improvement of the charge collection length and consequently increasing of electron hole pairs generation through the junction 43 . Moreover, the alignment of bandgaps plays important role to improve the V oc value where with small band gap for ZrS 2 than 1.45 eV more confinement take place and therefore the intra-band tunneling for carriers at the interface voltage barrier increases and more current generated 46 .…”

ZrS2 is transition metal dichalcogenides (TMDCs) which is believed one of the most talented applicants to fabricate photovoltaics. Therefore, we present here for the first-time numerical simulation of novel inorganic ZrS2/CuO heterojunction solar cells employing SCAPS-1D. The influence of the thickness, carrier concentration, and bandgap for both the window and absorber layers on the solar cell fundamental parameters was explored intensely. Our results reveal that the solar cell devices performance is mainly affected by many parameters such as the depletion width (Wd), built-in voltage (Vbi), collection length of charge carrier, the minority carrier lifetime, photogenerated current, and recombination rate. The η of 23.8% was achieved as the highest value for our simulated devices with the Voc value of 0.96 V, the Jsc value of 34.2 mA/cm2, and the FF value of 72.2%. Such efficiency was obtained when the CuO band gap, thickness, and carrier concentration were 1.35 eV, 5.5 µm, and above 1018 cm−3, respectively, and for the ZrS2 were 1.4 eV, 1 µm, and less than 1020 cm−3, respectively. Our simulated results indicate that the inorganic ZrS2/CuO heterojunction solar cells are promising to fabricate low-cost, large-scale, and high-efficiency photovoltaic devices.

“…An optimum V oc of 0.67 V was achieved with increasing doping concentration, and the current density J sc decreased with increasing doping concentration, indicating that the presence of doped impurity impacted J sc . The current density is defined as follows [30] J ¼ J S ðe qV=nKT À 1Þ À J sc (15) The highest value recorded is 45.4 mA cm À2 , and FF increased until the CuInSe 2 doping concentration reached 1 Â 10 16 cm 3 , after which it decreased due to a decrease in the J sc , demonstrating that the Jsc was affected by the presence of doping concentration impurities.

Herein, a CuInSe2 thin film solar cell with an intrinsic thin layer (HIT) is modeled and simulated using SCAPS. The HIT is deposited between a thin CdS window layer of reduced thickness of 20 nm to minimize cadmium toxicity and an absorbing layer of variable thickness. The aim is to study the influence of the thickness of absorber and HIT layer, level doping and defect densities of CuInSe2 layer, and high work function (between 5 and 5.6 eV) effect on performance parameters of the solar cell. In general, a significant increase in efficiency is observed. The HIT and the absorber thicknesses are optimized to be 0.3 and 0.5 μm, respectively. A conversion efficiency of 24.2%, a V oc of 0.78 V, J sc of 45.4 mA cm−2, and an FF of 68.3% are obtained for the proposed AZO/ZnO/CdS/CuInSe2/Mo/glass. These simulation results encourage using intrinsic thin layers in CIS solar cell structure.

This study systematically investigates the impact of various layers of the back surface field (BSF) on the performance of CH₃NH₃SnI₃ (MASnI₃)‐based lead‐free mixed organic–inorganic halide perovskite solar cells. By employing SCAPS‐1D (Solar Cell Capacitance Simulator in One Dimension) simulation software, the behavior of solar cells is analyzed incorporating BSF layers of CuI, NiO, ZnTe, and CBTS. The findings indicate that the inclusion of these BSF materials significantly enhances power conversion efficiency (PCE), with CBTS showing the highest PCE of 33.57%. The energy band diagrams reveal that the BSF layers effectively reduce recombination losses at the rear interface and improve charge carrier collection. Detailed analysis of photovoltaic parameters, such as open‐circuit voltage (Voc), short‐circuit current density (Jsc), fill factor (FF), and overall PCE, underscores the superiority of CBTS as optimal BSF materials. Temperature variation studies demonstrate that CBTS maintains superior performance across a range of temperatures, highlighting its potential for high‐efficiency, thermally stable perovskite solar cells. This comprehensive investigation provides valuable insights for optimizing the design and performance of MASnI₃‐based perovskite solar cells, with the aim of efficiencies greater than 33%.
