Herein, three different backsurface‐filed (BSF) layers “SnS, PbS, and V2O5” are investigated on Mo/BSF/CZTS/CdS/AZO heterojunction solar cells using experimental data of CdS thin films. CdS thin films are produced by means of the pulsed laser deposition (PLD) technique with three different deposition periods. With increasing deposition time, the crystalline sizes of CdS thin films are larger and their crystal structures are developed. In addition, the optical bandgap of CdS thin films is calculated to be 2.4 eV using the absorbance data. Using the solar cell–capacitance–simulator‐1D (SCAPS‐1D) program, the experimental properties of CdS thin films to estimate the performance of p‐CZTS/n‐CdS/AZO heterojunction solar cells are introduced. The best efficiency is 9.32% when the thickness of CdS reaches 150 nm. To further improve the efficiency, different BSF layers (SnS, PbS, and V2O5) are tested in Mo/BSF/CZTS/CdS/AZO solar cells. According to the thickness of the BSF layer, the efficiency of the solar cell increases up to 13.47%, 14.7%, and 17.41% using SnS, PbS, and V2O5 as BSF layers with 0.1 μm thickness.

“…Then, the Tauc method relates absorption coefficient to photon energy to calculate the bandgap energy. Only then can the wavelength be calculated from bandgap energy utilizing Equation (1). On the other hand, using the PL method, the wavelength can be obtained from the excitation curve, and then the bandgap energy can be calculated utilizing Equation (2).…”

“…A solution will be to investigate other materials that might qualify to fill the gap and be used as replacements. Metal oxides are one of these materials that are readily available and currently have a low cost of manufacturing [1]. In addition, copper oxides also have low toxicity, low bandgap, and a high absorption coefficient which are all valuable qualities.…”

Solar energy is becoming more popular and widespread, and consequently, the materials to manufacture solar cells are becoming more limited and costly. Therefore, in order to keep solar energy affordable and available, we must research alternative materials such as copper oxides. Some benefits of copper oxides include being available in abundance, affordable, low toxicity, low bandgap, and a high absorption coefficient-all of which contribute to it being a valuable interest for the manufacturing of solar cells. In this study, CuO thin films were synthesized utilizing RF sputtering technique with deposition occurring at room temperature followed by thermal annealing between 100˚C and 400˚C and using different gases, oxygen (O 2 ) (oxidizing and reactive gas) and nitrogen (N 2 ) (inert gas), besides air. Afterwards, these thin films were evaluated for a range of wavelengths: 200 -400 nm (UV spectrum), 400 -700 nm (Visible spectrum), and 700 -800 nm (IR spectrum), for both, optical transmittance and photoluminescence. In addition, the CuO results were compared to our Cu 2 O results from a previous study to assess their differences. In the results of this study, the CuO thin film initially had a bandgap of 2.19 eV at room temperature, and by increasing the annealing temperature to different levels, the bandgap decreased respectively. The presence of air in the chamber allowed for the highest decrease, followed by the nitrogen (N 2 ) and the lowest decrease was observed in the presence of oxygen (O 2 ). This was reflected in the decrease in the bandgap values from 2.19 eV (room temperature) to 2.05 eV for the films annealed at 400˚C.

“…30 The energy band alignment of ntype ZnO is suitably matched with p-type CuO. 31,32 Therefore, ZnO could be a promising electron transport layer (ETL) for the CuO-based solar cells. Furthermore, few research groups have experimented on ZnO-CuO-based solar cells in recent years, but the reported efficiency of these solar cells is very low.…”

In this research, a heterostructure of the CuO-ZnO-based solar cells has been fabricated using low-cost, earth-abundant, non-toxic metal oxides by a low-cost, low-temperature spin coating technique. The device based on CuO-ZnO without a hole transport layer (HTL) suffers from poor power conversion efficiency due to carrier recombination on the surface of CuO and bad ohmic contact between the metal electrode and the CuO absorber layer. The main focus of this research is to minimize the mentioned shortcomings by a novel idea of introducing a solution-processed vanadium pentoxide (V 2 O 5 ) HTL in the heterostructure of the CuO-ZnO-based solar cells. A simple and low-cost spin coating technique has been investigated to deposit V 2 O 5 onto the absorber layer of the solar cell. The influence of the V 2 O 5 HTL on the performance of CuO-ZnO-based solar cells has been investigated. The photovoltaic parameters of the CuO-ZnO-based solar cells were dramatically enhanced after insertion of the V 2 O 5 HTL. V 2 O 5 was found to enhance the open-circuit voltage of the CuO-ZnO-based solar cells up to 231 mV. A detailed study on the effect of defect properties of the CuO absorber layer on the device performance was theoretically accomplished to provide future guidelines for the performance enhancement of the CuO-ZnO-based solar cells. The experimental results indicate that solution-processed V 2 O 5 could be a promising HTL for the low-cost, environment-friendly CuO-ZnO-based solar cells.
