However, further materials and device optimizations are still necessary due to the considerably large voltage losses compared to traditional inorganic counterparts such as Si or GaAs. In this study, we employed various characterization methods to present a systematic investigation based on fluorinated donors and nine different acceptors to determine the role of donor fluorination in the performance of organic solar cells, especially the voltage losses. We found that the devices with fluorinated PM6 as donor exhibit significantly lower voltage losses (including radiative and non-radiative) than the ones with non-fluorinate PBDB-T donor when paired with different typical non-fullerene and fullerene acceptors, which can be attributed to the reduced charge transfer state reorganization energies, lower Urbach energy, and enhanced radiative decay rate. In addition, the PM6-based devices exhibit generally larger deep trap energy than the PBDB-T ones, but it is not the determinant to the voltage losses. These results enable us to identify the key features for minimizing the voltage losses and suggest that molecular design strategies focusing on the reduction of reorganization energy along with Urbach energy and increase of radiative decay rate is crucial for further improving the performance of organic solar cells.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"8 ","pages":"Article 100546"},"PeriodicalIF":0.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can be produced at lowcost, and on flexible substrates. They have tunable bandgap making them suitable for a range of applications. However, the thermal instability of these devices is still a challenge for their commercialization. Recently, all-inorganic PSCs based on CsPbI₂Br emerged as a new potential candidate for photovoltaic applications due to their long-term thermal stability. Solar Cell Capacitance Simulator (SCAPS-1D) software can be used to simulate and analyze the performance of perovskite solar cells. It can be used to study device modeling, solar cell parameter extraction, device optimization, and its comparison with experimental data. Here we have used SCAPS-1D to analyze the device parameters of inorganic perovskite solar cells (n-i-p configuration) with varying hole transport layers (HTLs) and electron transport layers (ETLs). Initially, different HTLs such as CuI, Cu₂O, CuSCN, and MoO_x are employed keeping ETL (TiO₂) and the absorber layer (CsPbI₂Br) fixed. The highest performance is obtained for devices containing CuSCN as HTL. Furthermore, device performance is further checked by varying the ETL such as ZnO, WS₂, and SnO₂ keeping HTL (CuSCN) and absorber layer (CsPbI₂Br) constant. The results showed that the device with configuration FTO/TiO₂/CsPbI₂Br/CuSCN/Fe shows better performance. In addition, for each device configuration, the effect of the charge transport layer’s thickness, the effect of absorber layer thickness, band gap, and defect density on the performance of the device has also been studied to obtain the best device performance. The thickness of the charge transport layers, and the absorber layer greatly affect the transport of photo-generated charges within the device. The highest power conversion efficiency (PCE) obtained for n-i-p configuration with TiO₂ (10 nm), CuSCN (30 nm) and absorber layer CsPbI₂Br (520 nm) is 14.66 %.The corresponding fill factor (FF) for the given configuration is 76.57 %, with short circuit current density (J_SC) of 16.4 mA/cm², and open circuit voltage (V_OC) of 1.16 V.
