- The realization of polymer solar cells is the driving force behind this research. In an idea inspired by photosynthesis, the authors have constructed efficient bilayer photodiodes by a well-chosen combination of conjugated polymers (see Figure) in the donor layer. Forster energy transfer within the donor layer allows the absorbed light to be channeled to the C-60 acceptor layer, improving the total photoconversion of the blend device.

Trapping light in polymer photodiodes with soft embossed gratings

- Increasing the conversion efficiency is very important in photovoltaic devices, as is cheap and simple technology. Here is demonstrated a soft embossing technique for printing a submicrometer grating with an elastomeric mold into an optically active polymer layer in a photovoltaic device (see Figure). The light trapping due to the grating pattern enhances the photoconversion efficiency by more than 25 % at normal light incidence (see also inside front cover).

High-performance polymer solar cells of an alternating polyfluorene copolymer and a fullerene derivative
- 2003

- High-performance polymer solar cells of an alternating polyfluorene copolymer, PFDTBT, and a fullerene derivative were studied. It was shown that PFDTBT is a promising candidate for obtaining high energy conversion efficiency when combined with a suitable electron acceptor. Results showed that high-performance solar cells with extended spectral coverage and increased open-circuit voltage could be prepared from composites prepared from electron acceptor.

Soluble polythiophenes with pendant fullerene groups as double cable materials for photodiodes
- 2001
-
Ingår i: Advanced Materials. - 0935-9648 .- 1521-4095. ; 13:24, s. 1871-
-
Tidskriftsartikel (refereegranskat)abstract
- A novel "double cable" material for photodiodes, containing both electron- and hole-transporting functional groups, is obtained by co-polymerization of thiophenes that bear a covalently linker-bound fullerene (see Figure). Even at 14% of fullerene substitution, the order of the main polythiophene chain is not seriously disturbed.
