PHOTOACTIVE COMPOSITION WITH A HIGH MOBILITY OF THE ELECTRONIC HOLES

摘要

A photoactive composition with a high mobility of the elec tronic holes, comprising: -at least one organic photoactive polymer; -at least one naphthalene diimide having general formul (I): wherein: - R1 and R2, the same or different, preferably the same, are selected from linear or branched C1-C36 alky1 groups, preferably C4-C24, optionally containing heteroatoms such as, for example, oxygen, nitrogen, sulphur; - R'1 and R'2, the same or different, preferably the same, are a hydrogen atom, or are selected from linear or branched C1-C10 alkyl groups, preferably C2-C6; they are preferably a hydrogen atom. - R11 and R20, the same or different, preferably the same, are a hydrogen atom, or are selected from linear or branched C1-C16 alkyl groups, preferably C2-C10; - R3, R4, R5, R6, R7, R8, R9, R10, R12, R13, R14, R15, R16, R17, R18 and R19, the same or different, are a hydrogen atom, or are selected from linear or branched C1-C16 alkyl groups preferably C2-C10; - a, b, c, d, e, f, g, and h, the same or different, are 0 or 1, on the condition that at least one is different from zero. Said photoactive composition with a high mobility of the electronic holes, can be advantageously used in the construction of photovoltaic devices, such as, for example, photovoltaic cells, photovoltaic modules, solar cells, solar modules, both on rigid and flexible support.
