In this lecture, we describe the basics of what quantum dots are and how they can be applied to thin film photovoltaic technologies. In particular, we examine the unique properties of quantum dot materials and how these properties can be exploited by scientists and engineers to yield low-cost, light-weight solar modules capable of converting sunlight into electricity in a direct fashion. Additionally, the basics of solar cell characterization and light absorption are detailed and related to the band gap of quantum dot materials. Finally, the potential impact of solar technologies on the energy landscape of the United States is discussed.
