Effect of intrinsic polymer properties on the photo sensitive organic field-effect transistors (Photo-OFETs)
Kosemen, Zuhal Alpaslan; Kosemen, Arif; Ozturk, Sadullah; Canimkurbey, Betul; San, Sait Eren; Yerli, Yusuf; Tunc, Ali Veysel (ELSEVIER SCIENCE BV, 2016)In this work, we have demonstrated how the intrinsic properties of a conjugated polymer can influence the electro-optical characteristics of photo sensitive organic field - effect transistors (Photo-OFETs). Photo-OFETs ... -
Fabrication and investigation of P3HT:PCBM bulk heterojunction based organic field effect transistors using dielectric layers of PMMA:Ta2O5 nanocomposites
Canimkurbey, Betul; Kosemen, Zuhal Alpaslan; Cakirlar, Cigdem; San, Sait Eren; Yasin, Muhammad; Berber, Savas; Kosemen, Arif (ELSEVIER SCIENCE BV, 2017)In this work, we have fabricated top-gate/bottom-contact type Organic Field Effect Transistors (OFETs). A poly(3-hexylthiophene) (P3HT): [6,6]-phenyl C61-butyric acid methyl ester (PCBM) blend with 1:1 wt/wt ratio was used ... -
Fe doped TiO2 thin film as electron selective layer for inverted solar cells
Kosemen, Arif; Kosemen, Zuhal Alpaslan; Canimkubey, Betul; Erkovan, Mustafa; Basarir, Fevzihan; San, Sait Eren; Ornek, Osman; Tunc, Ali Veysel (PERGAMON-ELSEVIER SCIENCE LTD, 2016)Inverted P3HT:PCBM based organic solar cells were fabricated by using Fe2+ doped TiO2 films as electron selective layer. Pure and Fe2+ doped TiO2 films were prepared by sol gel method and the optical as well as the structural ... -
