Abstract: Pure ɣ-Fe2O3nanoparticles are prepared by photo irradiation method using complexes solution of iron and successfully used as a photoanode for dye-sensitized solar cells (DSSCs). The samples were characterized by using powder XRD, SEM, TEM, UV-Visible and Current-Voltage curve. Results show that nanoparticles have uniform cubic shape with average size of 17 to 26 nm and it isapplied to fabricate novel Dye solar cellwhich has energy conversion efficiency about 4.13 % by (ITO/ Ɣ-Fe2O3Nps/ Dye (Rhodamine 6 G) /iodine / Ag film / ITO).
