Polymer Photovoltaic Cells: Enhanced Efficiencies via a Network of Internal Donor-Acceptor Heterojunctions
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
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
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
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
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.
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
Because the photoluminescence in the conducting polymer is quenched by interaction with C60, the data imply that charge transfer from the excited state occurs on a picosecond time scale.
Thermally Stable, Efficient Polymer Solar Cells with Nanoscale Control of the Interpenetrating Network Morphology
By applying the specific fabrication conditions summarized in the Experimental section and post‐production annealing at 150 °C, polymer solar cells with power‐conversion efficiency approaching 5 %
Efficiency enhancement in low-bandgap polymer solar cells by processing with alkane dithiols.
By incorporating a few volume per cent of alkanedithiols in the solution used to spin-cast films comprising a low-bandgap polymer and a fullerene derivative, the power-conversion efficiency of photovoltaic cells is increased from 2.8% to 5.5% through altering the bulk heterojunction morphology.
Soliton excitations in polyacetylene
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
