In this paper the brush painting as well as the dip-coating techniques have been investigated as methods for the production of organic solar cells and conductive polymeric lamellar structures, respectively. In particular we report on brush painting of a blend of a soluble diarylanthracene molecule and [6,6]-phenyl C61-butyric acid methyl ester for the realization of solar cell with a power conversion efficiency of 2.21%. As second case study we describe how the dip-coating of regioregular poly(3-hexylthiophene) can facilitate its self-assembly in films with nanofibrillar structure after the evaporation of the solvent. The condition for the formation of the nanofibrillar structures leads to an improved electrical conductivity of the polymer film.

Abstract
In this paper the brush painting as well as the dip-coating techniques have been investigated as methods for the production of organic solar cells and conductive polymeric lamellar structures, respectively. In particular we report on brush painting of a blend of a soluble diarylanthracene molecule and [6,6]-phenyl C61-butyric acid methyl ester for the realization of solar cell with a power conversion efficiency of 2.21%. As second case study we describe how the dip-coating of regioregular poly(3-hexylthiophene) can facilitate its self-assembly in films with nanofibrillar structure after the evaporation of the solvent. The condition for the formation of the nanofibrillar structures leads to an improved electrical conductivity of the polymer film.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
