摘要：
Dye-sensitized solar cells (DSSC) have been assembled using natural dyes extracted from the red (Gracilaria) and green (Ulva) algae as photosensitizers and the effect of adding Graphene quantum dot (GQD) has been investigated. The open-circuit voltage (VOC) values of natural dyes of Gracilaria, Gracilaria + GQD, Ulva, and Ulva + GQD are 0.64, 0.73, 0.70, and 0.75, respectively. The short circuit current density (JSC) values are varied from 0.96 to 2.26 mA cm−2, and the fill factor (FF) from 52 to 56% for the mentioned samples. The best-energy conversion efficiency of approximately 0.94% has been achieved for DSSC with Gracilaria + GQD with JSC equal 2.26 mA cm−2, VOC is 0.73 V, and FF is 56%.
