Definitions
- a solvent selected from alkylated tetralin, alkylated naphthalene and alkylated anisole, optionally with a second, different solvent is proposed to further tune the morphology of the photoactive layer.
- the present invention relates to a formulation comprising the aforementioned solvent blend, an n-type organic semiconductor, and a p-type organic semiconductor.
- the dialkylsubstituted aromatic hydrocarbon preferably comprises alkyl groups which may be independently selected from a C1 -C12 alkyl group or more preferably from a d-Ce alkyl group. More preferably, the dialkylsubstituted aromatic hydrocarbon is a dialkylbenzene, more preferably an ortho-dialkylbenzene, wherein the alkyl groups may be the same or different and may be selected from a C1 -C12 alkyl group or more preferably from a C1-C6 alkyl group.
- Ri and Fb independently represent d-Ce alkyl groups, which may be connected to each other to form a ring, and wherein R 3 represents hydrogen or a Ci-Ce alkyl group.
- the efficiency and photocurrent is believed to be controlled by inclusion of a main solvent which is typically good for solubilising both donor and acceptor materials and a higher boiling point additive which usually achieves good solubility for either the acceptor or the donor.
- the present invention relates to a method of manufacturing an organic electronic device comprising an anode, a cathode and a photoactive layer between the cathode and the anode, the method comprising: applying the formulation according to the above-described second embodiment by a solution deposition method to form a photoactive layer.
- Example 4 benzoate: 1 -methylnaphthalene 223 47.5 ⁇ 1 .4 ⁇ 42.6
