摘要：

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), P - V ), current density-voltage (J 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.
