Preparation and Performance Characterization of Perovskite/Organic Tandem Photovoltaic Devices:A Comprehensive Researching Chemistry Experiment
摘要
Abstract
Perovskite materials exhibit excellent optoelectronic properties and tunable bandgaps,making them a promising choice for efficient photovoltaic devices.Organic solar cells,with features like solution processing and flexibility,share a similar device structure with perovskite solar cells.Building perovskite/organic tandem structures can effectively enhance spectral utilization,surpassing the theoretical efficiency of single-junction devices,showing broader application potential.This experiment,starting from the forefront progress of tandem photovoltaic devices,recommends a comprehensive chemical design experiment for undergraduate students to understand the principles and advancements of perovskite/organic tandem cells,aiming to enhance their innovative thinking and experimental skills.The experiment involves tandem perovskite devices consisting of wide-bandgap perovskite front sub-cells,an intermediate layer,and organic rear sub-cells,covering thin film fabrication processes based on liquid-phase and vacuum deposition methods.Characterization of perovskite films'microstructure and crystalline properties is conducted using scanning electron microscopy and X-ray diffraction,while the photovoltaic performance of prepared tandem devices is measured using simulated sunlight and electrical testing systems.With moderate difficulty and rich content,this experiment aims to enable students to comprehend the working principles and frontier developments of photovoltaic devices,fostering their interest in solar cells and nurturing their research innovation and practical skills.关键词
