Conjugated polymers (CP), a solution-processable and mass-producible semiconducting material, are a promising candidate in the application of organic solar cells. One important factor that determines the light-electricity conversion efficiency of CPs is the morphology. My research will thus primarily investigate the method to control the microstructure of the thin films via accurate copolymerization. The ultimate goal of my project is to establish the knowledge about the relationship of molecular structure-morphology-optoelectronic performances, which contributes to the future design of high performance polymers in solar cells that could be mass manufactured.
