Electrical proprieties of self-assembled polymers prepared by spin coating route



Abstract. In the recent years, organic semiconductors are widely studied because they show a variety of electro-optical and electrical proprieties. Also it’s easy and facile to fabricate and process such kind of materials. Which make them promising as photovoltaic and optoelectronic devices [1-3]. In this study, we characterize and investigate electrical proprieties of ITO/PPEEB/Al structure. This structure is prepared by spin-coating. First PPEEB polymer is dissolved in chloroform solvent then coated on the substrate. Coated films on glass are used for optical characterization like transmission spectra in order to extract gap energy value. The transition is observed around 420 nm which correspond to electron transition between the valence band and conduction band equal to the gap energy of polymer Eg equal to 4eV. Second ITO substrate is used for electrical characterization, the Al electrode is deposited by thermal evaporation in vacuum on the top of structure.
