- 요약Bulk heterojunction (BHJ) organic solar cells (OSCs) have garnered significant attention due to their advantages such as lightweight design, high flexibility, and compatibility with large-scale solution-based manufacturing processes. However, outstanding issues such as morphological instability have remained a significant challenge in the field. This dissertation investigated the potential to tune the solubility parameters of conjugated polymers via side chain engineering, enabling the predictive manipulation of miscibility between donors and acceptors for organic solar cells. Molecular structure-miscibility-device efficiency relationships in OSCs are systematically investigated. Specifically, the Hansen solubility parameters (HSPs) of representative donor and acceptor polymers are broken down into separate contributions from their backbone and side chains. The effects of non-polar or polar side chains on the resulting solubility parameters are correlated to empirically and experimentally determined HSP. Furthermore, we establish a method to delicately tune the solubility parameters of conjugated polymers via the copolymerization of chemically different side chains, enabling the predictive manipulation of miscibility between donor polymers and a small-molecule acceptor for organic solar cells. Using this HSP framework, the possibility to predictively tune the solubility distance (Ra) between polymer donors and acceptors is established. This copolymerization strategy was used as a method to tune to a more 'optimal' position on the χ-ϕ phase diagram for a representative system (PTQ10:Y6), resulting in improved morphological stability. Coupled with the HSP framework and further evaluations, the ability to delicately tune and optimize the miscibility between polymer donors and acceptors can be achieved, creating new opportunities to pursue improvements in device efficiency and stability.
