  In the present study, dye-sensitized solar cells (DSSCs) were   fabricated by sensitizing TiO2 P25-based electrodes   using a series of natural dye extracted from plant sources of   Reseda luteola, Berberis integerrima,   Panica granatum Pleniflora, Consolida   orientalis, Reseda gredensis, Clemetis   orientalis, Adonis flammea, Salvia   sclarea, and Consolida ajacis. The optical   properties of the natural dye extracts were investigated by   UV–vis spectroscopy. The crystalline structure and morphological   characteristic of TiO2 electrode were analyzed by XRD   and SEM, respectively. Our findings showed that due to   Delphinidin is the main pigment of C. ajacis and   interaction between the hydroxyl groups of the Delphinidin and   the TiO2 surface is very efficient, this sensitizer   owns the best photovoltaic performance among the all natural   dyes. Photoelectrochemical performance of the natural dyes   based-DSSCs illustrated short-circuit photocurrent (Jsc)   and open-circuit voltages (Voc) ranging from 0.004 to   0.68 mA and 0.37 to 0.64, respectively.
