Abstract

This investigation posits the development of an economically feasible graphite-based carbon electrode for use in hole transport-free perovskite solar cells. The weight ratio of graphite was systematically optimized, and the incorporation of copper sulfide nanoparticles was implemented to augment the electrical characteristics of the carbon-based electrode. Copper sulfide nanoparticles were synthesized through a hydrothermal method and subsequently combined with pre-prepared carbon paste to produce CuS-modified carbon electrodes. The synthesized nanoparticles exhibit flower-like morphologies with crystalline nanosheets measuring approximately 30 nanometers. The influence of varying doping ratios of CuS nanoparticles on the electrical properties of carbon-based hole transport-free perovskite solar cells was meticulously examined. The integration of CuS nanoparticles into the carbon electrode facilitates enhanced charge extraction, thereby resulting in increased current density within the perovskite solar cells. The suggested carbon-based hole transport-free perovskite solar cell demonstrates adequate stability over a duration exceeding one year.

硫化铜纳米颗粒掺入对碳基无空穴运输钙钛矿太阳能电池的影响

本研究设想了一种经济可行的石墨基碳电极的发展，用于无空穴输运钙钛矿太阳能电池。系统地优化了石墨的重量比，并引入了硫化铜纳米颗粒来增强碳基电极的电特性。采用水热法制备了硫化铜纳米颗粒，并将其与预先制备好的碳糊结合制备了cu修饰的碳电极。合成的纳米颗粒呈花状形态，晶体纳米片尺寸约为30纳米。研究了不同掺杂比例的cu纳米粒子对碳基无空穴输运钙钛矿太阳能电池电性能的影响。将cu纳米颗粒集成到碳电极中有助于增强电荷提取，从而增加钙钛矿太阳能电池内的电流密度。所建议的碳基空穴无输运钙钛矿太阳能电池在超过一年的持续时间内表现出足够的稳定性。图形抽象

期刊介绍： The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
