Abstract
The technology behind organic solar cells (OSC) requires significant improvement to gather commercial interests for private companies to the same degree as silicon based solar cells. The unstable morphological nature of the active layer of OSCs is aimed to be improved by synthesizing both donor and acceptor semiconductor together as copolymers. Both vinyl and non-vinyl polymerization were attempted. The first synthetic step for monomer towards the vinyl copolymer has been performed thoroughly. For the non-vinyl polymerization, a well-known Suzuki cross-coupling reaction between a donor and an acceptor semiconductor was performed once, and twice under an emulsion polymerization in order to obtain donor-acceptor polymer particles in the nanometer range. In such size, these copolymers may be dispersed in water despite their hydrophobic nature which is of great interest for large-scale manufacturing.
