The main objective of this work is to prepare the solar active materials such as TiO2 with help of dye. The Rhodamine-B modified TiO2 (RhoB-TiO2) composite will used as DSSC. The PL studies are carrying out by the emission and excitation of TiO2 is increased after addition of Rhodamine-B. UV study showed that the composite energy gab has shifted towards the visible region in electromagnetic spectrum (Red shift), and then band gap is indirect and allowed transition. In this type of RhoB-TiO2 composite used for fabrication of optoelectronic device and fabrication of DSSC.
