Polymer Photovoltaic Cells: Enhanced Efficiencies via a Network of Internal Donor-Acceptor Heterojunctions
- G. Yu, J. Gao, J. Hummelen, F. Wudl, A. Heeger
- ChemistryScience
- 15 December 1995
The carrier collection efficiency (ηc) and energy conversion efficiency (ηe) of polymer photovoltaic cells were improved by blending of the semiconducting polymer with C60 or its functionalized…
Bulk heterojunction solar cells with internal quantum efficiency approaching 100
- S. H. Park, A. Roy, A. Heeger
- Chemistry, Physics
- 1 May 2009
A polymer solar-cell based on a bulk hetereojunction design with an internal quantum efficiency of over 90% across the visible spectrum (425 nm to 575 nm) is reported. The device exhibits a…
Synthesis of electrically conducting organic polymers: halogen derivatives of polyacetylene, (CH)x
- H. Shirakawa, E. Louis, A. MacDiarmid, C. Chiang, A. Heeger
- Chemistry, Materials Science
- 1977
When silvery films of the semiconducting polymer, trans‘polyacetylene’, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly…
Solitons in polyacetylene
- W. Su, J. Schrieffer, A. Heeger
- Physics
- 18 June 1979
We present a theoretical study of soliton formation in long-chain polyenes, including the energy of formation, length, mass, and activation energy for motion. The results provide an explanation of…
Efficient Tandem Polymer Solar Cells Fabricated by All-Solution Processing
- J. Y. Kim, Kwanghee Lee, A. Heeger
- Materials ScienceScience
- 13 July 2007
Tandem solar cells, in which two solar cells with different absorption characteristics are linked to use a wider range of the solar spectrum, were fabricated with each layer processed from solution…
Electrical Conductivity in Doped Polyacetylene.
- C. Chiang, C. Fincher, A. MacDiarmid
- Materials Science
- 24 October 1977
Doped polyacetylene forms a new class of conducting polymers in which the electrical conductivity can be systematically and continuously varied over a range of eleven orders of magnitude. Transport…
Photoinduced Electron Transfer from a Conducting Polymer to Buckminsterfullerene

Soliton excitations in polyacetylene
- W. Su, J. Schrieffer, A. Heeger
- Physics
- 15 August 1980
A theoretical &n ~lysis of the excit ~tion spectrum of long-chain polyenes is presented. Because of the twofold degeneracy of the ground state of the dimerized ch ~in, element ary excit~tions…
