The invention concerns a method for producing a self-assembled block copolymer film on a substrate, said method consisting of simultaneously depositing block copolymer and statistical copolymer by means of a solution containing a mixture of block copolymer and statistical copolymer having different chemical natures and being immiscible, then of carrying out an annealing treatment so as to promote the segregation of phases inherent to the self-assembling of the block copolymers.

The invention relates to novel block copolymers that enable a good dispersion of nanofillers in water and also to a dispersion of nanofillers obtained owing to these block copolymers. This dispersion may be used as a transparent electrode in organic solar cells or other photoemitter or photoreceptor devices.

The present invention relates to a composition of an active film of an organic photovoltaic cell, comprising: an electron-donor material consisting of a conjugated polymer; and an electron-acceptor material consisting of a polymer, characterized in that the active film comprises a copolymer with a linear structure comprising: two to five blocks, at least two blocks of which have different chemical natures; two consecutive blocks having different chemical natures; each block having a molar mass of between 500 g/mol and 50,000 g/mol. The invention also relates to an organic-cell-based photovoltaic module incorporating such a composition and the use of this composition for the same purposes.
