제목 Preparation of anatase TiO2 by low temperature annealing for inverted organic photovoltaic cells
초록 To prepare the anatase TiO2 thin films on ITO glass, amorphous TiO2 colloidal solution was synthesized through simple sol-gel method by using titanium (IV) isopropoxide as a precursor. The average particle size of amorphous TiO2 colloidal solution was about 1.0 nm and that of anatase TiO2 colloidal solution was 10 nm. The thickness of TiO2 films was ~15 nm for all cases. When inverted polymer solar cells were fabricated by using these TiO2 films as an electron transport layer, the device C showed the highest PCE (2.6 %) due to the lack of defect, uniformness and high light absorbance of TiO2 films. The result of this study can be applied for the preparation of inverted polymer solar cell using TiO2 films as a buffer layer at low temperature.
