Wednesday, October 11, 2006, 11:00 am — Hamilton Seminar Room, Bldg. 555
In this talk, I will focus on the physics of organic photovoltaic cells, and how to use this to optimize device architecture and conversion efficiency. The various architectures of the bulk, or mixed heterojunction, tandem cells, and double heterostructure will be full explained. I will discuss the influence of the structural morphology of vacuum thermally evaporated thin films on device performance. For tandem cells, I will discuss the role of surface plasmons on metal nanoclusters, as well as the importance of optical modelling by virtue of a transfer matrix approach. In addition, I will discuss the origin of the open-circuit voltage in donor/acceptor photovoltaic cells, as well as strategies to extend the sensitivity of organic solar cells out into the near infrared spectral region.
