Phase mixing behaviour in evaporated thin films

Abstract: The photovoltaic active layer of organic photovoltaics (OPVs) consists of a mixture of at least two kinds of energetically offset organic molecules, which gives rise to a complex microstructure across multiple length scales from Angstroms to micrometres. A common method to study the mixing of Polymer:Fullerene systems has been Small Angle Neutron Scattering (SANS), but the advantages of this technique have so far remained little exploited for vacuum evaporated small molecule-based systems, which are closest to commercial viability. We have recently successfully demonstrated the use of SANS to study the mixing behaviour of OPV evaporated thin films. We seek to expand upon our preliminary results to study the phase behaviour of vacuum evaporated thin films when the mixing ratio and substrate temperature is varied, and the effects on performance and characteristics of matching devices.
