The main purposes of this study are replacing conventional hydro-thermal method by microwave heating
using water as reaction medium to rapidly synthesize TiO2.Titanium tetraisopropoxide (TTIP) was hydrolyzed in
water. The solution is subsequently processed with microwave heating for crystal growth. The reaction time could
be shortened into few minutes. Then we chose different acids as dispersion agents to prepare TiO2 paste for
investigating the effects of dispersion on the power conversion efficiency of dye-sensitized solar cells (DSCs). The
photovoltaic performance of the microwave-assisted synthesized TiO2 achieved power conversion efficiency of
6.31% under AM 1.5 G condition (100 mW/cm2). This PCE value is compatible with that of the devices made from
commercial TiO2.
