Oligomer-like small molecule based tandem solar cells with >12% PCEs (Conference Presentation)

Organic solar cells with >12% PCEs Yongsheng Chen The College of Chemistry & School of Materials Science and Engineering Nankai University Tianjin, CHINA Email: yschen99@nankai.edu.cn Polymer/organic photovoltaic has been thought as one of the promising technology to face the increasing energy and environmental issues. In this talk, a series of high performance oligomer-like organic small molecules and their OPV devices will be discussed. Particularly, tandem cells using all small molecules with >12% PCEs will be presented in details.
