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 ...
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 ...
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 ...
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 ...
