Indium tin oxide-free and metal-free semitransparent organic solar cells
(Georgia Institute of Technology, 2010-10)
We report on indium tin oxide (ITO)-free and metal-free semitransparent organic solar cells with a high-conductivity poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) (PH1000) as both the bottom and the ...
A hybrid encapsulation method for organic electronics
(Georgia Institute of Technology, 2009-04)
We report a thin-film encapsulation method for organic electronics that combines the deposition of a layer of SiOₓ or SiNₓ (100 nm) by plasma enhanced chemical vapor deposition followed by a layer of Al₂O₃ (10–50 nm) by ...
Origin of the open-circuit voltage in multilayer heterojunction organic solar cells
(Georgia Institute of Technology, 2008-11-10)
From temperature dependent studies of pentacene/C₆₀ solar cells in the dark, the reverse saturation current is found to be thermally activated with a barrier height that corresponds to the difference in energy between the ...
Exciton dissociation and charge trapping at poly(3-hexylthiophene)/phenyl-C61-butyric acid methyl ester bulk heterojunction interfaces: Photo-induced threshold voltage shifts in organic field-effect transistors and solar cells
(Georgia Institute of Technology, 2012-04)
Photoinduced charge transfer at an electron donor/acceptor interface is one of the most crucial processes in determining the power conversion efficiency of organic solar cell devices. Here, we address exciton dissociation ...
Thin Film Solar Cells. New Organic Materials, Large-scale Printing and Nanoparticles
(Georgia Institute of Technology, 2013-08-21)
In this seminar I will present three main areas of our work on solution processed solar cells. In part one I will describe the development of new donor and acceptor materials for solution processed organic photovoltaics ...
