Abstract
Yb2O3-doped TiO2 were prepared using mechanochemical process to obtain Dye Sensitized Solar Cells (DSSCs) photoanodes. The parameters of DSSC devices were calculated. The study showed that the addition of Yb2O3 improved the open-circuit voltage via a p-type effect, whereas, a negative effect on the generated photocurrent was observed. This reduction in photocurrent was attributed to increasing crystal defects as a result of increasing the concentration of Yb2O3 dopants.
