In this study, the charge transfer characteristics of an organic semiconductor device are controlled by changing the crystal characteristics of the organic semiconductor layer. After integrating the organic nanoparticles, cellulose nanowhisker (CNW), into the TIPS-Pentacene organic semiconductor layer, the temperature of the fabrication substrate was changed to change the crystal shape of the organic semiconductor layer. The crystals of the organic semiconductor layer changed depending on the heat of the substrate and the presence or absence of organic nanoparticles, which affected the charge transfer and charge accumulation mechanism of the organic semiconductor device. I-V, C-V and C-F electrical measurements were performed to analyze the charge mechanism of organic semiconductor devices and to investigate the relationship between the crystal properties of organic semiconductor layers and charge transfer.
