摘要： The present invention relates in a first aspect to methods for producing a nanofibres-containing layer for use as an active layer in an organic electronic device. The method comprising the steps of: a) first heating up a nanofibre-forming polymer in a solvent at a temperature T1, then b) cooling said solution down to a temperature T2 at a rate less than 40° C./h thereby forming a dispersion comprising crystalline nanofibres of said nanofibre-forming polymer, then c) raising the temperature of said dispersion to a temperature T3 higher than T2, but lower than said temperature T1, and then d) coating said dispersion on a substrate at said temperature T3 thereby forming a layer for use as an element of said organic electronic device, wherein before step (d), a step of adding an electron acceptor to the solution or dispersion is performed.
