“…11,12 One strategy implemented is the use of a double buffer layer composed of TiO 2 and CdS to reduce the thickness of the CdS buffer layer, i.e., from 103 to 20 nm, 13 which in turn decreases the CdS parasitic absorption and toxicity. [13][14][15] It is also important to note that a further post-treatment process of the CdS buffer layer is necessary to enhance the charge transport properties and film quality of the CdS buffer layer, including the nonenvironmentally friendly CdCl 2 16 and hydrazine. 17 Hybrid nanocomposites based on CdS and carbon nanostructures, such as carbon nanotubes (CNTs), 18 reduced graphene oxide (RGO), 19 and carbon dots, 20 have attracted attention due to their beneficial effects for optoelectronic and energy applications.…”

“…Therefore, the ETL of TiO 2 for Sb 2 Se 3 solar cells needs to work better. 22 As far as we know, many studies have been conducted using the SCAPS-1D software in ideal conditions to investigate how and when antimony trisulfide solar cells act. However, only a small number of researchers have implemented the simulation software to analyze how the less-than-ideal conditions mentioned above affect the performance of antimony trisulfide solar cells.…”

For many years, scientists have wrestled with the disparity between solar cell modeling and real results. Especially, simplified assumptions fabricated by simulation programers can be the best normal reason for this report. However, by using certain nonideal conditions, the simulated solar cell may mimic real conditions in some modeling programs. Using the SCAPS-1D (SCAPS = Solar Cell Capacitance Simulator) program, we endeavored to simulate the representative FTO/TiO2/Sb2Se3/spiro-OMeTAD/Au antimony chalcogenide solar cell (spiro-OMeTAD = 2,2′,7,7′-tetrakis-[N,N-di-(p-methoxyphenyl)amino]-9,9′-spirobifluorene) while accounting for resistance pathways and recombination processes (radiative and Auger). To achieve this, the power of each nonideal condition was prosperously studied. The proficiency results of the investigated solar cell revealed a remarkable variation between the device’s efficiency before and after applying these conditions, ranging from 25% to more than 8.40%. Significant reduction in the efficiency can be attributed to the radiative recombination of the solar cell (active layer). In order to maximize each critical characteristic of the active layers, the influence of the previously ascribed parameters, comprising the doping density and inclusive thickness, was studied with regard to efficiency and integration plots. During the simulation phase, this investigation was novel in that it approximated the outcomes of the aforementioned experimental investigations under nonideal circumstances. Furthermore, employing recombination plots considerably assisted in selecting the appropriate layer characteristic, such as doping density. After adjusting each of the aforementioned settings, the efficiency increased by approximately 4% and a power conversion efficiency of approximately 29% was accomplished. Overall, the results revealed that despite a remarkable drop in cell execution, the simulated cell was more representative of actual conditions and provided a more accurate model for a solar cell.

The strong Ti-O bonds in TiO 2 and poor compatibility to Sb 2 Se 3 result in poor performance when used as electron transport layers (ETL) for Sb 2 Se 3 solar cells. Therefore, cadmium sul de is usually used as a buffer layer to improve its compatibility. In the present work, we deposited a layer of CdS by spin coating method on TiO 2 ETL and fabricated TiO 2 /CdS dual ETL. The CdS layer improved the electronic properties of TiO 2 and grain orientation of Sb 2 Se 3 thin lms. As a result, the average short circuit current and ll factor of Sb 2 Se 3 solar cells were improved, and the nal champion power conversion e ciency was enhanced from 2.6-4.71%. This study supplied a route for the application of titanium dioxide as a broadband gap electron transfer material in Sb 2 Se 3 solar cells.
