Objective
On the path to enhancing photovoltaic (PV) materials and surpassing their efficiency limits, one promising approach is to exploit the phenomenon of singlet fission (SF). This process involves high-energy singlet excitons generated by light absorption in organic molecules, which interact with nearby ground-state molecules to produce two triplet excitons. This intricate interaction significantly boosts the efficiency of photovoltaic devices. Given the scarcity of SF materials and the advantageous properties of polymers in PV applications, this project aims to address the challenge by employing advanced polymer synthesis techniques.
The project’s hypothesis centers on designing monomers inspired by known singlet fission small molecules. The following steps involve utilizing controlled polymerization strategies to create polymers with various topological structures. These polymers will be combined with PbS quantum dot materials to produce composite films with SF properties through spin coating. By adjusting the polymer topology to fine-tune the stacking configuration of the polymer chains, the photophysical properties of the materials can be precisely controlled. Through detailed analysis of these photophysical properties, the relationship between polymer structure and photophysical behavior will be established. Ultimately, this will lead to the development of a new generation of composite singlet fission photovoltaic materials, enabling the creation of high-performance photovoltaic devices that surpass the theoretical limits of traditional photoelectric conversion efficiency.
Through advanced polymer synthesis, precise photophysical analysis, and fine-tuned thin-film optimization, this research will unlock the potential of singlet fission, significantly impacting polymer materials. It will pave the way for new photovoltaic materials, contributing to clean energy and promoting environmental sustainability.
