WebbA graph is drawn between light intensity along x-axis and the photocurrent along y-axis. From the graph in Figure 7.9, it is evident that photocurrent – the number of electrons emitted per second – is directly proportional to the intensity of the incident light. Here, intensity of light means brightness. Webbwere compared in dark and under UV-C light to determine the photocurrent. These measurements presented distinct results for the undoped and the doped materials, such as modification in photocurrent under UV-C illumination. SrTiO3@SrCO3 composite electrodes show important characteristics which could be classified as a potential …
