Research Interests

Developing organic semiconductors for efficient and stable perovskite solar cells

Organic molecules show great promises as charge transport materials in organic electronics due to their defined structure and structural diversity. Additionally, their optoelectronic properties can be well tuned by modifying the chemical structures. Spiro-OMeTAD is one of the most efficient and widely used hole transport materials (HTMs) for perovskite solar cells (PSCs). However, tedious synthesis and high cost of spiro-OMeTAD significantly limit the large scale application in the solar cells. Therefore, developing new alternative molecules with high efficiency and simple synthesis is highly desired. In this project we fundamentally investigate the relationship between molecular structure, properties and solar cell performance, and try to design simple but efficient molecules to replace spiro-OMeTAD.


Large scale, low temperature processed perovskite solar cells

New deposition method for scalable perovskite is essential for its future application. The goal is to develop low temperature processed charge transport materials and perovskite on large area substrates.
