Giant conductance of PSS:PEDOT micro-surfaces induced by microbubble lithography
Anand Dev Ranjan, Rakesh Sen, Sumeet Kumar +5
We provide direct evidence of the effects of interface engineering of various substrates by Microbubble lithography (MBL). We choose a model organic plastic (or polymer) poly(3,4-e…
Nature of excitons in PPDT2FBT: PCBM solar cell: Role played by PCBM
Subhamoy Sahoo, Dhruvajyoti Barah, Dinesh Kumar S +4
In organic semiconductor based bulk heterojunction solar cells, the presence of acceptor increases the formation of charge transfer (CT) excitons, thereby leading to higher exciton…
Identification of the nature of excitons in PPDT2FBT using electroabsorption spectroscopy
Subhamoy Sahoo, Rajdeep Dhar, Sanjoy Jena +3
Electroabsorption (EA) measurements can be used to identify the type of excitons contributing to the absorption spectra of semiconductors which have applications in optoelectronics…
Pitch-rotational manipulation of single cells and particles using single-beam thermo-optical tweezers
Sumeet Kumar, M. Gunaseelan, Rahul Vaippully +5
3D pitch rotation of microparticles and cells assumes importance in a wide variety of applications in biology, physics, chemistry and medicine. Applications such as cell imaging an…
Modeling of Organic Metal-Insulator-Semiconductor Capacitor
Prashanth Kumar Manda, Logesh Karunakaran, Sandeep Thirumala +2
In this paper, we demonstrate the principle of operation of a metal-insulator-semiconductor (MIS) capacitor based on undoped organic semiconductor. In spite of low charge concentra…
Analytical and numerical modeling of capacitance voltage characteristics of organic solar cells
Prashanth Kumar Manda, Soumya Dutta
We report a charge based model to establish the analytical equation, describing the nature of capacitance-voltage (-) characteristics of organic solar cells under dark condit…
