Stanford solar research receives $25 million grant

The center will be directed by Michael McGehee, associate professor of materials science and engineering. The deputy director is Peter Peumans, assistant professor of electrical engineering in the Integrated Circuits Laboratory at the Center for Integrated Systems, who is also affiliated with the Woods Institute for the Environment. Both are intensely involved in designing new types of solar cells at the nanoscale level.

McGehee said that the center's goal is to make solar electricity at a cost that is competitive with coal plants. He seeks to construct organic solar cells that can be cheaply printed in a roll-to-roll coating process similar to newspaper printing. Today's best organic solar cells have an efficiency of 6.5 percent and last approximately one year under sunlight. The center has plans for taking the efficiency to at least 15 percent and making the cells stable for 10 years or more.

"We're doing lots of experiments to see what's holding back the efficiency," McGehee said.
