摘要：In this paper, have been discussed systematic studies of surface Modified TiO2. The samples arecharacterized by XRD, FE-SEM, PL, UV and I-V. The main objective of this work is to prepare the PV materialsuch as TiO2 with help of dyes. The surface modified TiO2 (Hes-TiO2) composite will used as DSSC. The PL studiesare carrying out by the emission and excitation of TiO2 and Hes-TiO2. UV study showed that the composite energygab has shifted towards the lower wavelength in electromagnetic spectrum (blue shift), and then optical band gap isan indirect and allowed transition. In this type of Hes-TiO2 composite used for fabrication of optoelectronic device,because the quantum yields of the TiO2 and Hes-TiO2 approximately equal to the unity. The solar energy conversionefficiency is increased 70% for the surface modified-TiO2 as compared to TiO2.
