A composition of an active film of an organic photovoltaic cell, including: an electron-donor material having a conjugated polymer; and an electron-acceptor material having a polymer, wherein the active film comprises a copolymer with a linear structure including: 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. Also, an organic-cell-based photovoltaic module incorporating such a composition and the use of this composition for the same purposes. |
