| Abstract | In this work, organic photosensitizer has been synthesized for dye-sensitized solar cells (DSSCs). The solar cells then fabricated have been characterized by photocurrent-voltage characteristics and electrochemical impedance spectroscopic (EIS) measurements. The effect of outdoor temperature on the photovoltaic performance of DSSCs has also been investigated here. The results indicate that DSSC shows power conversion efficiency of 2.58% at 25 °C under air mass (AM) 1.5 G illumination at 100 mW/cm2. It has also been found out that the efficiency of DSSCs drops with the rise of temperature. The decrease in efficiency can be attributed to decrease in open-circuit voltage of cells. The EIS analysis shows that increase in temperature also reduces the charge recombination resistance mainly due to decrease of electron lifetime. These findings demonstrate that the cell is stable up to 35 °C. |
