    Abstract: Organic photovoltaic performance has been investigated about the fluorination effects as one part on the optoelectronic properties. The quantum chemical accuracy of the optoelectronic and structural properties based on D-A (Donor-Acceptor) conjugated copolymers as PDTPQX-type (Poly-dithieno-pyrrol-Quinoxaline) has been tediously exposed. The Donor-... Show More
