Benzodithiophene and selenophene bearing polymer for inverted organic solar cell applications Toppare, Levent Kamil; Yaşa, Mustafa; Göker, Seza; Udum, Yasemin; Günbaş, Emrullah Görkem; Çırpan, Ali (null; 2018-07-06) Inverted organic solar cells have advantages over conventional organic solar cells. Most important advantage is the improved stability of inverted solar cells. In this study, benzodithiophene, quinoxaline and selenophene bearing conjugated polymer was used as donor material in inverted solar cell applications. Device performances were investigated with the device configuration of ITO/ ZnO/ polymer:PC71BM/ MoO3/ Ag. In order to improve device performance, polymer PCBM ratio, active layer thickness, annealing...
Benzodithiophene and Benzotriazole Bearing Conjugated Polymers for Electrochromic and Organic Solar Cell Applications UNLU, Naime Akbasoglu; HACIOGLU, Serife O.; HIZALAN, Gonul; Yildiz, Dilber Esra; Toppare, Levent Kamil; Çırpan, Ali (The Electrochemical Society, 2017-01-01) Herein, alternating donor-acceptor type benzodithiophene and benzotriazole bearing copolymers were synthesized and thieno[3,2-b] thiophene and furan units were incorporated as pi-bridges. The application of these polymers for electrochromic and photovoltaic studies were performed. Spectroelectrochemical studies illustrate that both polymers showed multichromic behavior due to tailoring of polaron bands in visible region. Photovoltaic properties of P2 were performed by conventional device structure. The best...
Benzotriazole and Benzodithiophene Containing Medium Band Gap Polymer for Bulk Heterojunction Polymer Solar Cell Applications UNAY, Hande; UNLU, Naime A.; HIZALAN, Gonul; HACIOGLU, Serife O.; Yildiz, Dilber Esra; Toppare, Levent Kamil; Çırpan, Ali (Wiley, 2015-02-15) An alternating donor-acceptor copolymer based on a benzotriazole and benzodithiophene was synthesized and selenophene was incorporated as -bridge. The photovoltaic and optical properties of polymer were studied. The copolymer showed medium band gap and dual absorption peaks in UV-Vis absorption spectra. Photovoltaic properties of P-SBTBDT were performed by conventional device structure. The OSC device based on polymer: PC71BM (1:1, w/w) exhibited the best PCE of 3.60% with a V-oc of 0.67 V, a J(sc) of 8.95 ...
Benzotriazole Derivatives as Long Wavelength Photosensitizers for Diaryliodonium Salt Initiators Bulut, Umut; Balan, Abidin; Caliskan, Cagin (Wiley, 2011-02-01) Two benzotriazole derivative dyes 4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2-dodecyl-2H-benzo[1,2,3]triazole, and 2-dodecyl-4,7-bis(4-hexylthiophen-2-yl)-2H-benzo[d][1,2,3]triazole are shown to work as efficient photosensitizers for a dipheny-liodonium salt initiator in cationic photopolymerization of epoxide and vinyl monomers. Substituted thienyl groups are attached to benzotriazole backbone to extend conjugation and enhance electron density of the molecules. Thereby, it was possible to initiate ...
