Development of new organic semiconducting materials for organic photovoltaics (Conference Presentation)

Organic semiconductors have been studied extensively with regards to their charge transport ability and have recently been demonstrated to be a viable option for large-area, commercial electronic devices and photonics. Thus far, various synthetic strategies for organic semiconductors have been reported to enhance their performance. Firstly, we developed small molecule organic semiconductors for solution processed solar cell because of high reproducibility, easy purification, and more over high crystallinity with oustanding stacking properties.
