Recent Advances in Wide Bandgap Polymer Donors and Their Applications in Organic Solar Cells

Organic solar cells (OSCs) have attracted wide research interests in the past decades. In recent years, our group mainly focused on the new photovoltaic materials design and device engineering technologies for highly efficient OSCs. This account mainly summarizes our recent studies on the structural design of wide bandgap (WBG) polymers and their morphology control as well as applications in OSCs. Additionally, we introduce our work on binary and ternary blend devices and tandem solar cells containing these materials. What is the most favorite and original chemistry developed in your research group? We focus on design and synthesis of high-performance organic semiconductors for photovoltaic applications. Our interests are exploring the relationships between the conjugated molecular structures and their photovoltaic properties. How do you get into this specific field? Could you please share some experiences with our readers? When I was in Singapore and USA as a postdoctoral research fellow, I found that the energy crisis and environmental pollution were becoming more and more serious. I believed that organic solar cell (OSC) would be sprung up in the near future and I needed to do something about it. Therefore, I begun to follow with interest the OSCs in 2006 and got into this field in 2007. How do you supervise your students? I am in pursuit of development on self-thinking abilities of my students. More specifically, encourage and guide the students to find the problems, analyze the problems and figure out some ways to resolve the problems. What is the most important personality for scientific research? Intelligence, diligence and perseverance. What is your favorite journal(s)? Those journals with high scientific nature and good timeliness. Also, the reported results shall be reliable and repeated easily.

Automated summary

The research group focuses on the design and synthesis of organic solar cells, exploring the relationship between conjugated molecular structures and photovoltaic properties. The field expert, following the energy crisis and environmental pollution, began to track organic solar cells in 2006 and entered the field in 2007. In supervising students, emphasis is placed on developing students' independent thinking and problem-solving abilities.
