Photo-anodes based on TiO2 have been widely used in DSSC devices. However, TiO2 has a high rate of electron recombination, thus limiting the energy conversion of the DSSC. One of the strategies to increase TiO2 capability is to perform surface functionalization with other materials such as carbon. Carbon has a large specific surface area, high electron mobility, excellent optoelectronic and electrocatalytic properties. Activated Carbon (AC) is an allotrope of carbon with the highest surface area, while Black Carbon (BC) has better electrical conductivity. Surface area and electrical conductivity are important parameters to produce high-efficiency DSSC. In this research, the effect of TiO2/C (C = AC and BC) nanocomposites as a photo-anode for DSSC have been investigated. The TiO2/C photo-anode was fabricated by a doctor blade method. It is found that TiO2/C nanocomposite improves efficiency DSSC based on TiO2. The optimum performance was obtained on TiO2/AC photo-anode with an efficiency of 0.475%. © 2023 American Institute of Physics Inc.. All rights reserved.
