Abstract    Rapid growth energy demand and environmentally concerns have led to renewable energy sources. Dye-sensitized solar cells (DSSCs) as new technology were employed for green energy preparation. The chemical structure engineering of photosensitizers acts a very important role in photovoltaic devices such as dye-sensitized solar cells. For this end, two organic dyes contain indigo group for increasing light resistance and various anchoring group for improving interaction were designed and prepared. Cyanoacrylic acid and acrylic acid were employed as anchoring groups. All intermediates and dyes were purified and analyzed using analytical techniques.The results show that all expected chemical structure of dyes was achieved. Two semiconductor namely TiO2 and ZnO were selected for photoanode preparation and all dyes were coated on them. All prepared samples illustrated blue shift in UV-Visible due to J-aggregation of dyes on semiconductor. The CV and DFT results were confirmed the application of synthesized dyed in the structure of DSSCs. The prepared dyes were applied in DSSCs structure as photosensitizers. The efficiency photosensitizer contains cyanoacrylic acid in DSSCs based on TiO2 and ZnO is 4.22 and 5.16, respectively. The results show that the performance of DSSCs based on TiO2 is better than of DSSCs based on ZnO. The results show that the cyanoacrylic acid is better anchoring group compared to the acrylic acid
