TUTORIAL




H/I: Organic Photovoltaics―Current Challenges and Opportunities



Sunday, November 27
8:30 am-5:00 pm
Hynes Convention Center

The tutorial covers fundamental and device aspects of organic photovoltaics, including materials design principles, interfaces, multi-scale modeling, and novel device designs. The tutorial will begin with a general overview of organic photovoltaics. The materials session will focus on: how to change the bandgap; the acceptor strength; how to improve the stability, charge mobility; controlling the morphology, etc., with relevant examples from highly performing OPV materials. The interfaces session will detail issues such as dipole formation, alignment/bending of energy levels, challenges in predicting the energetic alignment and charge transport through OPV devices and explaining experimental methods to investigate these issues. The multi-scale modeling session will describe physical models such as charge transport and recombination and simulation principles. Methods of and challenges to implementing physical models in Monte Carlo and macroscopic device simulations will be explained. The device designs session will focus on methods to enhance the energy conversion efficiency of various device structures, optimizing process conditions, and novel device architectures.
