Progress and challenges in Polymer OPV solar cells.

**Seminars begin at 4:00 PM and will be held in Clark Hall Room 101**

In this presentation, I will discuss strategies to prepare highly efficient OPV solar cells and the current challenges we are facing.  Our recent results on investigation of low bandgap polymers lead us to conclude that not only the energetics but also the internal polarization along the polymer chain is critical in facilitating charge transfer to PCBM, which were shown to be partially responsible for the high PCE device made from these low bandgap copolymers.  More evidences based on polydispersity effect support this hypothesis.  I will discuss our recent effort in developing ternary OPV cells and their mechanistic studies.
