UCF secures $7.5 million research grant to improve hybrid photovoltaic solar cells

October 27, 2009

The University of Central Florida has been awarded a $7.5 million research grant to study ways to make photovoltaic solar cells more efficient in capturing and converting solar energy into electricity and less costly to manufacture.

The research can lead to ways to produce highly flexible solar panels, which could be manufactured in larger quantities and used to support a variety of solar products, spanning from solar roof shingles to portable energy.

The grant, from New York-based Prime Source Initiative, Inc., will be awarded in $1.5 million allotments per year for five years.

The research will be led by Winston Schoenfeld, a professor in CREOL, The College of Optics and Photonics at UCF. He will work on methods to increase the efficiency between the organic material that harvests the sun's energy and the inorganic semiconductor nanostructures within a hybrid photovoltaic solar cell.

"All-organic solar cells are effective at absorbing light and collecting energy from the sun, but they aren't efficient at converting this into electricity," Schoenfeld explained.

Hybrid solar cells use an inorganic semiconductor (such as silicon) to increase electric output. But how to efficiently and economically integrate the organic and the inorganic components of the hybrid solar cell is a challenge and hasn't been widely studied.

Schoenfeld will develop the inorganic, nanostructured semiconductor backbone of the solar cell. The project's co-researcher, Andre Gesquiere, a professor in UCF's Nanotechnology Science Center and the Chemistry Department, will lead the organic, polymer research components of the project.

"Once the light is absorbed in the polymer, excitons are created that must be separated. If you don't separate them, they'll just recombine and you lose that energy," Schoenfeld said. "So we are using inorganic nanostructures that act as 'transport highways' to allow an efficient way for excitons to be separated and transferred into electricity."

The research will seek to answer questions such as how close together and how long the nanostructures should be made within the solar cell. Researchers also will attempt to increase the absorption capability of the organic material so that more of the solar spectrum can be harvested.

Schoenfeld cautioned that while the research goal is to identify efficient solar devices in the laboratory, the discoveries have to meet the demands of deployment into the marketplace.

"We have to think of the constraints of the end product. Will it be expensive to manufacture? Will the end-product be able to capture the aesthetic properties that will actually sell? Is there enough demand in other geographic areas? These are all factors that drive what products can eventually emerge from the laboratory."

Schoenfeld said this research project will emphasize collaboration with other researchers.

"A large grant can spawn three or four researchers to come together and go after challenging multi-disciplinary ideas, bringing vision into reality," Schoenfeld said. "The real value in this grant will be the ability to create these new collaborative connections, putting UCF in a unique position to make significant progress in the area of photovoltaic research."
