Abstract

In this study, titanium dioxide (TiO₂) nanoparticles were obtained via a hydrothermal method, while graphene oxide (GO) nanoparticles were produced via Hummers’ method. Reduced graphene oxide/titanium dioxide (RGO@TiO₂) nanocomposites were synthesized via a hydrothermal technique. The structural, morphological, and optical properties of TiO₂, RGO@TiO₂, and perovskite nanoparticles were characterized via powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and ultraviolet-visible spectrophotometry. Fourier transform infrared spectroscopy (FTIR) was used to study the functional groups in the samples. Additionally, thermogravimetric analysis (TGA) and differential thermal analysis (DTA) were also used to investigate how samples undergo structural and phase changes throughout a thermal process. This study investigated the enhancement of cell efficiency with lightening. In this work, FTO/Ag/TiO₂/perovskite/spiro-OMeTAD/Ag, FTO/Ag/RGO@TiO₂/perovskite/spiro-OMeTAD/Ag, and FTO/Ag/perovskite/spiro-OMeTAD/Ag structured solar cell devices were fabricated and subjected to two different light treatments, ultraviolet (UV) and LED lamps, to determine how cell efficiency is affected by light. After lighting with a 7-W LED lamp, the perovskite solar cells (PSCs) with the structure of FTO/Ag/RGO@TiO₂/perovskite/spiro-OMeTAD/Ag showed a higher efficiency of 17.01% compared with that of the other materials, FTO/Ag/perovskite/spiro-OMeTAD/Ag 8.61%, and FTO/Ag/TiO₂/perovskite/spiro-OMeTAD/Ag 15.62%. It can be concluded that using the RGO@TiO₂ nanocomposite material in the fabrication of PSCs enhanced the cell efficiency.

基于 TiO2、RGO@TiO2 和 SnO2:F 电子传输层制造的 MAIPbI2 包光体太阳能电池

在这项研究中，二氧化钛（TiO2）纳米粒子是通过水热法获得的，而氧化石墨烯（GO）纳米粒子则是通过 Hummers 法生产的。通过水热技术合成了还原氧化石墨烯/二氧化钛（RGO@TiO2）纳米复合材料。通过粉末 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和紫外-可见分光光度法对二氧化钛、RGO@TiO2 和透辉石纳米粒子的结构、形态和光学特性进行了表征。傅立叶变换红外光谱（FTIR）用于研究样品中的官能团。此外，还使用了热重分析（TGA）和差热分析（DTA）来研究样品在整个热过程中如何发生结构和相变。本研究探讨了如何通过减光提高电池效率。在这项工作中，制作了 FTO/Ag/TiO2/perovskite/spiro-OMeTAD/Ag、FTO/Ag/RGO@TiO2/perovskite/spiro-OMeTAD/Ag 和 FTO/Ag/perovskite/spiro-OMeTAD/Ag结构太阳能电池器件，并对其进行了紫外线（UV）和 LED 灯两种不同的光处理，以确定光对电池效率的影响。用 7 瓦 LED 灯照射后，FTO/Ag/RGO@TiO2/perovskite/spiro-OMeTAD/Ag 结构的过氧化物太阳能电池（PSCs）的效率比其他材料高 17.01%，FTO/Ag/perovskite/spiro-OMeTAD/Ag 为 8.61%，FTO/Ag/TiO2/perovskite/spiro-OMeTAD/Ag 为 15.62%。由此可以得出结论，使用 RGO@TiO2 纳米复合材料制造 PSCs 提高了电池效率。

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
