Synthesis of bistriphenylamine and benzodithiophene based random conjugated polymers for organic photovoltaic applications Çetin, Aslı; Çırpan, Ali; Department of Chemistry (2018) Nowadays, traditional fossil fuels have become unable to compensate huge energy demand of the world due to the population increasing day by day and bringing about destructive greenhouse effect. Owing to all of these problems, renewable energy sources such as solar energy not only can be candidate for the solution of this expanded energy need but also can protect the earth by reducing the production of greenhouse gas. In this study, electronic, optical features and photovoltaic applications of two novel orga...
Synthesis of selenophene substituted benzodithiophene and fluorinated benzothiadiazole based conjugated polymers for organic solar cell applications Cevher, Duygu; Taşkaya Aslan, Sultan; Bolayır, Eda; Hizalan Ozsoy, Gonul; UDUM, YASEMİN; Yıldırım, Erol; Toppare, Levent Kamil; Çırpan, Ali (2021-12-01) A series of alternating conjugated copolymers which contain selenophene modified benzodithiophene and fluorine bearing benzothiadiazole have been synthesized via Stille polycondensation reaction to investigate the effect of the number of fluorine atoms substituted to the benzothiadiazole. Three different polymers, PBDTSe-BT, PBDTSe-FBT and PBDTSe-FFBT, were reported and their electrochemical, spectroelectrochemical, and photovoltaic behaviors were examined. Density functional theory calculations were perfor...
Synthesis of bistriphenylamine- and benzodithiophene-based random conjugated polymers for organic photovoltaic applications CETIN, Asli; ISTANBULLUOGLU, Cagla; HACIOGLU, Serife Ozdemir; CEVHER, ŞEVKİ CAN; Toppare, Levent Kamil; Çırpan, Ali (2017-11-15) In this study, donor-acceptor random polymers containing benzotriazole acceptor and bistriphenylamine and benzodithiophene donors, P1 and P2, were successfully synthesized by Stille coupling polymerization. The effect of bistriphenylamine moiety and thiophene -conjugated linker on electrochemical, spectroelectrochemical, and optical behaviors of the polymers were investigated. Optoelectronic properties and photovoltaic performance of the polymers were examined under the illumination of AM 1.5G, 100 mWcm(-2)...
