Improving the photovoltaic response of a poly(3-octylthiophene)/n-Si heterojunction by incorporating double-walled carbon nanotubes [PDF]

, 2007
Poly(3-octylthiophene)/n-Si heterojunction solar cells were studied with and without incorporation of double-walled carbon nanotubes (DWCNs) in the polymer layer. The performance of the device improves significantly by the incorporation of DWCNs.

Semitransparent Organic Solar Cells

Frontiers of Optoelectronics, 2014
The organic solar cell technology has attracted great interests due to its potential of low cost solution process capability. Bulk heterojunction organic solar cells offer a potentially much cheaper alternative way to harness solar energy, and can be made flexible and large area. They can also be made translucent and in different colors.
