DOE grant funds solar energy project

April 01, 2008

Competitively priced electricity from easily manufactured solar cells is the aim of a Penn State researcher's project funded for up to $1,231,000 over three years by the U.S. Department of Energy.

Craig A. Grimes, professor of electrical engineering will partner with Honeywell to develop solar cells for efficient, low-cost, large area scalable solar energy conversion. The solar cells will be based on titanium dioxide nanotubes and organic semiconductors.

The DOE is investing up to $13.7 million in 11 breakthrough solar energy projects. Each recipient and their industrial partner are expected to supply at least 20 percent of the total cost. The aim of the program is to help industry partners to advance manufacturing processes and products. To this end, projects are expected to retain commercialization focus and move toward rapid transitions to market ready products and manufacturing.

Grimes' project builds on his existing titanium dioxide nanotube and organic semiconductor solar cell that has a conversion efficiency of 4.7 percent. He plans to experiment with a variety of combinations of tube lengths and thicknesses and pore sizes to arrive at the best combination to achieve photconversion efficiencies of 6 to 8 percent.

To achieve better efficiency, Grimes will optimize the nanotubes; develop a better pentacene, derived die to capture the sunlight; and investigate ways to scale up the device for large-scale energy production.

#537 Science Journalism, Hold the Hype
Everyone's seen a piece of science getting over-exaggerated in the media. Most people would be quick to blame journalists and big media for getting in wrong. In many cases, you'd be right. But there's other sources of hype in science journalism. and one of them can be found in the humble, and little-known press release. We're talking with Chris Chambers about doing science about science journalism, and where the hype creeps in.
