TREND: Optical Probes of Charge Generation and Recombination in Bulk Heterojunction Organic Solar Cells

Ian A. Howard, Frédéric Laquai*

Understanding the principles of charge generation and recombination in organic solar cells is a prerequisite for future material development and device optimization. Optical probes, especially transient absorption spectroscopy, are valuable tools to study the dynamics of excited states such as excitons and charges, over a wide-range of timescales. New insights from recent studies may help to guide the future material development without having to rely on entirely empirical strategies for device optimization.
