Abstract

Titanium dioxide (TiO2 ) is a wide band-gap n-type semiconductor. Anatase TiO2 is the most common structure used in high performance dye-sensitized solar cell (DSSC). Nanoporous TiO2 serves double-duty as an electron acceptor and a scaffold to hold large numbers of dye molecules in DSSC. The porosity of TiO2 is a key feature as it has roughly a thousand times greater a surface area than the equivalent flat area. In this work, TiO2 crystallite size (43.55 nm) has been calculated by using XRD data, and the morphology and the grain-size of TiO2 (average grain size of 0.2 m ~ 0.3 m) with different solvents have been also studied by SEM.
