About the Journal :
Experimental and Theoretical NANOTECHNOLOGY (ETN) abbreviated as Exp. Theo. NANOTECHNOLOGY is a multidisciplinary peer-reviewed and open access journal. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of nanotechnology with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics, materials science and medicine. ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
Materials and its properties are the main criteria to build its applications; some of the photovoltaic materials could be used in pure form to fabricate photovoltaic applications of the materials LCD (liquid crystal display), LED (Light emitting diodes), photodiodes and photo transistors. When it will be doped with oxide semiconducting materials its applications will be enhanced commercially. The resultant photovoltaic nanocomposites can be easily changed by its shape and parameters. The transparent conductor is applied to the touch screen panel and it is confirmed that all the final devices operates under continuous mechanical stress. This review gave the simple basic ideas of its development from 19 century to recent. The technologies of the photovoltaic applications and its electronic devices were dealt in this review. The unique optical properties of graphene were reported the use of solution processed high quality transparent conductive electrode in an organic solar cells. This review also deals with the reports of many researchers and their fabrications of thieno [3,4-b] thiophene/benzodithiophene:phenyl-C71-butyric acid methyl ester (PTB7:PCB71M) bulk heterojunction organic solar cell based on the exfoliated graphene (EG) anode exhibits a power conversion efficiency for next-generation flexible optoelectronic devices.
