TiO2 is a well-known material especially for organic solar cell. In this research the objective of this experiment that is to get high current that will improve the electron migration. The nanostructured TiO2 was deposited onto glass substrate using the well-known sol gel spin coating method. In this experiment, eight TiO2 solutions with different molarity were tested for their performance as the electron conductor layer in organic solar cell. The surface topology and morphology of nanostructured TiO2 was observed using the Atomic Force Microscopy (AFM) and Field Emission Scanning Electron Microscope (FESEM). The electrical properties were investigated by using two probe current-voltage (I-V) measurements to study the electrical resistivity behavior, hence the conductivity of the film. Based on the result, lower the molarity of TiO2, the surface becomes more uniform and the I-V becomes much better. As predicted, the best thin film characteristic is the 0.01M to be applied in organic solar cell in the future work.
