Abstract (en)

[origin: WO2013156609A1] The present invention relates to a method for preparing a photovoltaic thin film having a heterojunction by depositing a composition, including a first organic electron-donor semiconductor CP and a second organic electron-acceptor semiconductor CN, onto a substrate and then carrying out phase segregation, including: a step (E1) of preparing a first mixture M1 including the organic semiconductors CN and CP within a solvent medium; and then a step (E2) of adding an additive, having at least one N3 function, to said mixture.
