Plastic solar cells with engineered interfaces

SPIE Proceedings, 2013
We discuss here bulk-heterojunction polymer solar cells with engineered interfaces to achieve desired phase separations (vertical and horizontal), molecule orientations, ohmic contacts, and electronic properties for device performance maximization, and to enhance the device durability by eliminating corrosive interfacial layers.

Improving the efficiency of plastic solar cells

SPIE Newsroom, 2006
As the need for renewable energy sources becomes increasingly apparent, solar cells are attracting more attention. Those made from thin plastic films are particularly attractive because they are relatively easy to produce, structurally flexible, and can be applied to large areas at low cost.

Dithienothiophene based polymer as electron donor in plastic solar cells

Thin Solid Films, 2008
In this work we have tested in bulk heterojunction solar cells a polymer with a high oxidation potential, Poly-(dithieno[3,2-b:2?,3?-d]thiophene)-3-decylthiophene (P1), as electron donor together with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as electron acceptor.

New conjugated polymers for plastic solar cells

Energy & Environmental Science, 2011
The present review gives an overview of four of the most promising classes of conjugated polymers for plastic solar cells. The latest developments on poly(2,7-carbazole)s, poly(1,4-diketopyrrolopyrrole)s, poly(thieno[3,4-b]thiophene)s, and poly(thieno[3,4-c]pyrrole-4,6-dione)s are reported.

Device optimization in PCPDTBT:PCBM plastic solar cells

Solar Energy Materials and Solar Cells, 2010
Abstract We investigated device design parameters for low-bandgap conjugated organic polymer blends of poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b′]dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)]: phenyl-C 61 /C 71 -butyric acid methyl ester (PCPDTBT-PC 61 BM and PCPDTBT-PC 71 BM) used as photoactive components in polymer solar cells ...

Outlook Brightens for Plastic Solar Cells

Science, 2011
In early April, Mitsubishi Chemical reportedly set a new efficiency record, producing organic solar cells with a 9.2% conversion efficiency. Many researchers in the field are confident that the figure could soon top 10% and possibly reach 15%.

Large area plastic solar cell modules

Materials Science and Engineering: B, 2007
Abstract Preliminary data on the fabrication of 0.1 m 2 polymer solar cells are presented. The process employed screen-printing of an active layer onto an indium-tin-oxide (ITO) electrode pattern (50 Ω square −1 ) on a 200 μm polyethyleneterphthalate (PET) substrate.

Crystalline Organization of a Methanofullerene as Used for Plastic Solar‐Cell Applications

Advanced Materials, 2004
Crystalline organization of a methanofullerene, [6,6]‐phenyl C61 butyric acid methyl ester (PCBM), as achieved in various thin‐film deposition techniques, is reported. Mechanically stable, and thus self‐supporting, thin films obtained via fast solvent evaporation techniques are found to be composed of densely and homogeneously distributed PCBM ...

Plastic solar cells roll into unlit villages

IEEE Spectrum, 2009
By day, the electronic devices that Frederik Krebs rolls off his printing presses could be mistaken for old plastic overhead-projector transparencies. Nightfall reveals their ingenious purpose: Snap the metal fasteners at the corners together and the sheets glow with reading-quality light.

Protocrystalline silicon solar cells on transparent plastic substrates

2009 34th IEEE Photovoltaic Specialists Conference (PVSC), 2009
Here, we have investigated fabrication of thin film silicon p-i-n solar cells at low substrate temperatures. The effect of silane diluted by hydrogen, in i-layer deposition process on the solar cell characteristics has been studied. Our results show that the material right at the phase transition from amorphous to microcrystalline shows a combination ...
