Abstract: Solution-processed Organic Thin-Film Transistors (OTFTs) are of increasing interest because of its significant potential such as possibility of low-cost, flexibility and large-scale process. They also remarkable for their optoelectric characteristics, in other words, photosensitivity.?We have investigated an organic phototransistors using 6,13-Bis(triisopropylsilylethynyl)Pentacene(TIPS-Pentacene) and Titanium Dioxide (TiO2) nanocomposite materials for active layer. For this study, TiO2 nanoparticles composited with TIPS-Pentacene measured the electrical characteristics under illumination on off-state gate bias. This is able to explain with absorbance peak of particular wavelength. Also, We have obtained photocurrent continues a fairly long time which illumination is off. This means their probability of photo-switching devices and optical memories. For more detailed, various electrical and optical characteristics will be discussed.
