Organic small molecule (OSM) based materials have received great attention for solar energy conversion and utilization due to the many advantages, such as cost-effective, environmentally friendly, flexible, light weight. Rational design of OSMs for efficient solar energy conversion has been an active area of research. There are two types of OSMs depending on the types of excitons they generate. One type generates the Frenkel excitons upon UV-Vis absorption and the second type the Wannier excitons. The Wannier OSMs (WOSMs) have shown great promise in the development of long-persistent luminescence materials. In this presentation, we will provide strategies in the design of WOSMs and explore the photovoltaics performance of the WOSM materials. Characterizations of the excitonic properties of these materials will also be discussed to understand their device performances.
