研究目的
To design and synthesize two new wide bandgap block copolymers with porphyrin-incorporated side chains for use as electron donors in solution-processed bulk heterojunction polymer solar cells, and to investigate their photophysical, electrochemical, and photovoltaic properties, charge transport mobility, and film morphology.
研究成果
The study successfully synthesized two new block copolymers with porphyrin-incorporated side chains, which showed good solubility and thermal stability. The inclusion of porphyrin units broadened the absorption range and improved the photovoltaic performance, with PL2-based devices achieving a higher efficiency of 7.14%. The size of the porphyrin pendant was found to significantly affect the properties of the molecule, suggesting that careful design of the pendant can optimize the performance of polymer solar cells.
研究不足
The study focuses on the synthesis and characterization of two specific block copolymers and their application in polymer solar cells. The limitations include the specific conditions under which the polymers were synthesized and tested, which may not be universally applicable. Additionally, the study does not explore the long-term stability or scalability of the devices.
