Effects of Processing Conditions on Polymer Photovoltaic Device Performance
We will discuss recent results for the NREL polymer photovoltaics group. The work reported here explores the impact of polymer morphology on the physics and performance of polymer-based photovoltaic devices. By varying both the annealing temperatures and the solvent used for polymer deposition, we can alter the polymer chain morphology, thus shifting the absorption onset and shape and improving the charge transport properties of the resulting devices. The higher degree of order in the films results in increased photovoltaic performance.
