Nanoelectronics key to advances in renewable energy

Stephen Goodnick energy talk

ASU engineering professor Stephen Goodnick gave a presentation at the American Association for the Advancement of Science on what nanoelectronics can contribute to improving the effectiveness of solar-energy technologies.

Nanoscale technology looks promising as a major contributor to advancements needed to fulfill the potential of emerging sources of clean, renewable energy.

Progress in the comparatively new area of nanoelectronics in particular could be the basis for new manufacturing processes and devices to make renewable energy systems and technologies more efficient and cost-effective.

Stephen Goodnick recently detailed what nanoelectronics advances could do to help push the performance of solar energy systems to the next level in his talk at the 2014 annual meeting of the American Association for the Advancement of Science (AAAS) Feb. 13-17 in Chicago.

Goodnick is a professor in the School of Electrical, Computer and Energy Engineering, one of Arizona State University’s Ira A. Fulton Schools of Engineering, and deputy director of ASU LightWorks, a strategic framework for light-inspired research at ASU.

AAAS is the world’s largest science and technology society. Its annual meetings draw thousands of scientists, engineers, educators, policymakers and journalists from around the world.

Titled “Pathways to Next-Generation Photovoltaics,” Goodnick’s presentation looked at how innovations driven by nanoelectronics research can enable photovoltaic technology to significantly improve our ability to convert sunlight and heat into electric power.

He delved into how new types of nanostructure-based devices can make it possible to produce photovoltaic solar cells that achieve better energy-conversion efficiency.

Goodnick explained that the key is in the different characteristics, properties and behavior of materials at the nanoscale.

A nanometer is one-billionth of a meter (one meter is a little more the 39 inches long). About 100,000 nanometers amount to the same thickness as a typical sheet of paper. At that tiny scale, silicon and other materials that are used to make solar cells can perform in ways that boost the effectiveness of devices for producing energy, Goodnick says.

“With the use of nanoparticles, made into nanostructures, we could, for instance, improve optical collection, enabling systems to trap more light for conversion into electrical power,” he said. “Using nanomaterials, we could make solar cells even thinner but still more efficient, and we could increase the capacity of energy-storage devices.”

Such progress will hinge on the success of science and engineering research in overcoming current high production costs and some technical challenges. But Goodnick said he’s confident nanotechnology advances “are going to be big factors in the future of energy.”

Goodnick’s talk was part of an AAAS conference session that also featured presentations on aspects of nanoelectronics and renewable energy by four of his colleagues.

Beginning in July, Goodnick will join those fellow engineers and scientists in a research collaboration at the Institute for Advanced Study at the Technical University Munich in Germany.

Goodnick has been awarded the German university’s Hans Fischer Senior Fellowship, which will enable him to spend six months conducting research at the institute. The fellowship award is given to engineers and scientists doing innovative work in areas of interest to the institute.
