Finding economic ways to capture and convert energy from our largest renewable energy source, the sun, is becoming more urgent as the world’s supply of fossil fuels vanishes. Now, the development of a new generation of solar cells might lead the way toward a better future.
Graetzel cells, named for Professor Michael Graetzel of the Ecole Polytechnique fédérale de Lausanne (EPFL) in Switzerland, are dye-sensitized solar cells that are thin, flexible, and come in many shapes and colors, allowing them to answer different functional needs. Inspired by plant photosynthesis, they use dyes to transform sunlight into electricity.
Lausanne’s EPFL+ECAL Lab initiated a design workshop around Graetzel cells that resulted in the traveling exhibition, Sunny Memories, shown in cooperation with swissnex in San Francisco at the California College of the Arts‘ Wattis Institute for Contemporary Arts, from April 16 to 24, 2010.

In parallel to the exhibit, swissnex San Francisco presents an in-depth discussion of the technology behind the project. Brian Hardin, of the Material Science and Engineering Department at Stanford University, explains how dye-sensitized solar cells work and describes potential applications. Two of the leading manufacturers of the technology, Dyesol Inc. and G24 Innovations, present their market-oriented take on the groundbreaking innovation.

Brian Hardin is a fifth-year PhD student in the Material Science and Engineering Department at Stanford University. Mr. Hardin recently received the Material Research Society Gold Medal Award, the highest honor given to a graduate student in the field of Material Science, for his work on Dye-Sensitized Solar Cells. As a Swiss Fulbright Scholar, Mr. Hardin researched and developed dye-sensitized solar cells under the supervision of Professor Michael Grätzel at l’Ecole Polytechnique Fédérale de Lausanne in 2004-2005. Brian maintains close ties to the EPFL and Switzerland, returning several times a year to collaborate on research and hike in the Alps.

Howard M. Clearfield is the Chief Technology Officer at G24 Innovations, Ltd., a “personalized” solar energy start-up company specializing in flexible dye sensitized solar cells (DSSC). His solar energy experience includes positions at OptiSolar, Inc. as Director of Product Development, and at The Dow Chemical Company, where he installed at 210 kW solar farm that has produced over 750 MW-hr of renewable energy. Prior to entering the solar energy field, Clearfield was Global Leader of Technical Services and Applications Development for Dow’s LUMATION* Light-Emitting Polymers (LEPs). His group’s responsibilities included strategic marketing, customer technical support, and development/transfer of industrial ink processing techniques. He was also on the start-up team for Intarsia Corporation, a Silicon Valley company that produced thin film (passive) integrated circuits, from 1997 to 1999. From 1989 to 1996, he worked at IBM where his experience in thin film processing included projects ranging from fundamental studies of metal/polyimide interfaces to building thin film multichip module substrates for System 390 mainframe computers. He obtained a Ph.D. in Materials Science from The University of
Wisconsin in 1985.
