标 题 :In-situ polymerization in bulk heterojunction organic devices
发明人：ADE HARALD W; SEOK JAEWOOK
权利人:ADE HARALD W; SEOK JAEWOOK; UNIV NORTH CAROLINA STATE
摘要:Fabrication of bulk heterojunction organic devices are disclosed that utilize in-situ polymerization of an active component of the device or an in-situ polymerization of an additive that controls the device morphology. According to an aspect, a method for the synthesis of a BHJ photovoltaic film may comprise preparing a homogeneous solution comprising 2,5-dibromothiophene and/or 2,5-diiodothiophene, P3HT and PCBM. The method may also comprise preparing a thin film of the homogeneous solution on the solid surface of a material or an assembly capable of acting as an anode. Oxygen may be excluded from the environment where the thin film will be exposed to photopolymerization by placing the thin film and anode assembly in an inert-gas environment. The method also comprises exposing the liquid film to UV light for a sufficient duration of time and at a sufficient temperature to cause photopolymerization to occur.
