摘要

本研究展示了利用天然有机染料共敏化技术提高染料敏化太阳能电池（DSSC）光电效率的方法。研究人员使用来自鹅掌楸、马蔺和麝香果皮的颜料作为不同比例的共敏化剂，以确定光子捕获的最佳浓度。利用吸收光谱进行了光学表征，并通过功率-电压（P-V）、电流密度-电压（J-V）和电化学阻抗光谱（EIS）分析评估了光伏特性。与单个染料的 0.95 % 和 0.10 % 相比，使用鹅掌楸和麝香草染料的共敏化 DSSC 实现了 1.56 % 的最高功率转换效率 (PCE)。这些研究结果表明，通过与天然染料共敏化，可显著提高效率。

Enhanced photovoltaic efficiency in dye-sensitized solar cells with natural co-sensitizers from Annona squamosa, Malus domestica and Musa fruits

This study demonstrates the enhancement of photoelectric efficiency in dye-sensitized solar cells (DSSCs) using a co-sensitization technique with natural organic dyes. Pigments from Annona squamosa, Malus domestica, and Musa peels were used as co-sensitizers in various ratios to determine the optimal concentration for photon capture. Optical characterization was performed using absorption spectroscopy, while the photovoltaic properties were evaluated through power-voltage (P–V), current density-voltage (J-V), and electrochemical impedance spectroscopy (EIS) analyses. The co-sensitized DSSC with Annona squamosa and Malus domestica dyes achieved the highest power conversion efficiency (PCE) of 1.56 %, compared to 0.95 % and 0.10 % for the individual dyes. These findings underscore the significant efficiency gains achieved through co-sensitization with natural dyes.
