Charge transport in organic photovoltaic materials
Today I am chairing a session on charge transport at an I2CAM Exploratory Workshop, Complex Interactions and Mechanisms in Organic Photovoltaics being held here at UQ.
I have written quite a few posts on this topic before. I believe some of the key questions concerning charge transport in molecular materials are:
- What is the mechanism of charge transport?
- What is the origin of the observed electric field dependent mobility?
- What determines the relative magnitude of electron and hole mobilities?
- How does mobility depend on the intermolecular separation and relative orientation?
- Would thermopower measurements be helpful in determining the charge transport mechanism?
