Abstract: In this thesis, the engineering and investigation of interfacial materials (metal oxides, organic polymers and their hybrids) for high efficiency organic solar cells (OSCs) will be covered. Firstly, the synthesis and characterisation of zinc oxide nanoparticles (ZnO NPs) was introduced and subsequently applied as an electron transport layer (ETL) in highly efficient inverted OSCs. Next, a biopolymer poly(dimethylaminoethyl-methacrylate) (PDMAEMA) was introduced as a novel electron selective layer (ESL) for inverted OSCs. Factors for its successful implementation will be discussed. A hybrid inorganic nanoparticle-organic polymer material was developed as an ESL to overcome interfacial problems that occurred in inverted OSCs using polymeric interfacial materials. Lastly, a novel method for preparing aqueous inks for obtaining high work function films as hole selective layers (HSL) was developed. Our method does not involve the use of complex organometallic precursors or organic solvents and proves to be a facile method with potential for commercialisation.
