Carrier Lifetimes in Hybrid Perovskite Solar Cells

The United States is seeing a major shift in the way we view, produce, and consume energy. Currently less than 10% of energy comes from renewable resources, and just recently the federal government has taken legislative action to increase this number to 20% by 2020. Solar energy offers an inexhaustible resource that could significantly contribute to reaching this goal. To make this possible, the cost per kilowatt-hour of solar will have to be competitive with other leading technologies. This will require solar modules that are cheap, but also solar materials that are extremely efficient at absorbing light and converting this energy into electricity. I am currently studying an organic/inorganic perovskite material that has potential to meet both of these requirements. I am specifically interested in what happens in the solar cell right after it absorbs light and how to control these processes to design the most efficient solar material.

“Providing clean energy to the inhabitants of our planet is a major challenge to future generations. The University of Washington is to be congratulated for establishing an Institute where faculty and students can work together to tackle the difficult global challenge of energy sustainability.”
– Mildred Dresselhaus, Professor of Physics and Electrical Engineering, Emerita and Institute Professor, Massachusetts Institute of Technology
“Energy competition is opening up in a variety of ways, the push for carbon control will continue, and the rate of technology advancement is exponential. All the things I’ve seen at the CEI are just perfect for the way we see things going in energy. You guys are at the cutting edge. We’re counting on you.”
– Ronald Litzinger, President, Edison Energy
