摘要

为提升GeSe薄膜的光吸收性能和PCE,提出一种染料表面改性方法,使用罗丹明B（RB）、亚甲基蓝（MB）和刚果红（CR）等单染料及其混合物对GeSe薄膜进行修饰。实验结果显示,所有染料修饰后的GeSe薄膜光吸收能力均有显著提升,其中RB+MB混合染料效果最明显。通过Scaps-1D软件模拟不同染料修饰的GeSe薄膜太阳电池性能,发现MB修饰的GeSe薄膜PCE最高,达到26.32%,而RB+MB改性PCE较低,可能由于过高的染料负载与电池其他性能参数不匹配所致。研究证明了染料改性的可行性。

Abstract

To enhance the light absorption properties and PCE of GeSe thin films, this study proposes a dye-sensitization surface modification method, employing single dyes such as Rhodamine B （RB）, Methylene Blue （MB）, and Congo Red （CR）, as well as their mixtures, to modify the GeSe thin films. Experimental results show that the light absorption capacity of all dye-modified GeSe thin films is significantly improved, with the RB+MB mixed dye demonstrating the most pronounced effect. By simulating the performance of dye-modified GeSe thin-film solar cells using Scaps-1D software, it is found that the GeSe thin film modified with MB exhibits the highest PCE, reaching 26.32 %, whereas the RB+MB modification results in a lower PCE, possibly due to excessive dye loading not being well-matched with other cell performance parameters. This study demonstrates the feasibility of dye-based modification.
