Abstract


Over the past several years, the search for more efficient solutions to solar energy conversion has intensified, in large part driven by concerns over the impact of fossil energy sources on global climate. In my presentation I will provide a brief overview of the state-of-the-art in photovoltaics, and discuss key drivers in the development of new types of solar cells. I will also describe methods used in the characterization of solar cell performance. I will then give a brief overview of several categories of emerging solar cell technologies based on quantum confined semiconductor nanocrystals, and discuss some of the challenges associated with the optimization of their performance. In the second part of my talk I will explain the concept of photocatalysis, provide a brief historical overview of the field, and discuss several examples of photocatalytic systems based on quantum confined semiconductor nanocrystals.
