Encapsulation of pentacene/C₆₀ organic solar cells with Al₂O₃ deposited by atomic layer deposition
(Georgia Institute of Technology, 2007-06)
Organic solar cells based on pentacene/C₆₀ heterojunctions were encapsulated using a 200-nm-thick film of Al₂O₃ deposited by atomic layer deposition (ALD). Encapsulated devices maintained power conversion efficiency after ...
Recent Progress in Organic Solar Cells: From a Lab Curiosity to a Serious Photovoltaic Technology
(Georgia Institute of Technology, 2014-02-07)
Carbon-based organic semiconductors have many potential advantages like easy large-area preparation on flexible substrates, large variety of materials, and low cost. Although known for a century, organics have achieved ...
Area-scaling of organic solar cells
(Georgia Institute of Technology, 2009-09)
We report on the performance of organic solar cells based on pentacene/ C₆₀ heterojunctions as a function of active area. Devices with areas of 0.13 and 7 cm² were fabricated on indium-tin-oxide (ITO) coated glass. Degradation ...
An improved dynamic Monte Carlo model coupled with Poisson equation to simulate the performance of organic photovoltaic devices
(Georgia Institute of Technology, 2011-03)
We describe a new dynamic Monte Carlo model to simulate the operation of a polymer-blend solar cell; this model provides major improvements with respect to the one we developed earlier [J. Phys. Chem. B 114, 36 (2010)] by ...
Intensity-dependent equivalent circuit parameters of organic solar cells based on pentacene and C-60
(Georgia Institute of Technology, 2005-05)
We present studies of the current–voltage characteristics of organic solar cells based on heterojunctions of pentacene and C60 as a function of illumination intensity. The photovoltaic response at a given illumination level ...
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 ...
