Abstract

In the present work, yellow apple's skin, red apple's skin and Cercis siliquastrum’s petals have been used as pigments in dye-sensitized solar cells based on TiO2 nanoparticles. These pigments were extracted by a simple heat treatment method. In order to measure the absorption characteristics of pigments, ultraviolet-visible spectroscopy (Uv-Vis) analysis was used. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to investigate the structural characteristics and morphology of nanoparticles, respectively. The I-V curves of solar cells were drawn under standard conditions in light and dark states. The results show that the cells made using dyes extracted from yellow and red apple's skins and Cercis siliquastrum’s petals have short circuit currents of 27. 49 μA, 58. 50 μA and 173. 85 μA, respectively, and their open circuit voltages are 0. 53V, 0. 53V and 0. 55V, respectively. Their fill factors are equal to 0. 56, 0. 65 and 0. 68 respectively and their efficiencies are 0. 04%, 0. 08% and 0. 27% respectively.
