Abstract:
Dye-sensitize solar cells are the third generation solar cells that have attracted the attention of many researchers. In this cell, the dye is used as semiconductor paste sensors. Synthetic dyes, in addition to their high cost, are not environmentally suitable. Therefore, today, it is vital to find natural dyes to use in dye-sensitize solar cells with high efficiency. Syzygium cumini, commonly known as Jambo, is a native plant in the Indian subcontinent, the south of Iran, and the Persian Gulf zone. Every year a lot of the fruit of this tree is wasted without any use. In this study, in addition to the extraction of Jambo pigment and evaluation of its physical and electrochemical characterization, we used it in dye-sensitize solar cells. For this purpose, three types of titanium dioxide paste (acidic, ethanolic, and modified ethanolic) were used. The results indicated that the dominant pigment of Jambo was anthocyanin. By examining the photovoltaic performance of the cells made with Jambo pigment, it was found that the modified ethanolic paste has the best performance compared to the other pastes.
