Solar textile collaboration weaves chemistry and design

A new faculty member at the University of Wisconsin Madison, Marianne Fairbanks is bringing decades of experience with dyes, fibers and design to the development of a technology she been dreaming of for years: the solar textile.

found myself on a campus full of brilliant people of all disciplines so I just Googled research UW Madison,‹ says Fairbanks, assistant professor in the School of Human Ecology design studies program and co founder of Noon Solar, a Chicago based company that made solar charging handbags.

That search led her to Trisha Andrew, a rising star in energy research and assistant professor of chemistry at UW Madison. Andrew draws from the fields of chemistry, materials science and electrical engineering to develop low cost, lightweight solar cells.

Her most recent innovation is an organic dye based solar cell deposited onto paper.

Fairbanks comes from the art studio and Andrew the chemistry lab, but http://www.cheapjerseys11.com/ the two women had an instant, if unexpected, rapport. Fairbanks, who arrived to their first meeting with a stack of textiles, got Andrew thinking about fabric and, by the end of the encounter, the collaboration had begun.

Andrew and her team are currently coating different weave types and structures with a polymer that increases the fabric’s conductivity tenfold. Once fully coated, the fabric will serve as the bottom electrode, and a base layer on which to build the rest of the solar cell.

idea of building solar cells on fabric is potentially transformative, Andrew says. we take this technology to grow devices on material, then we could talk wearable technology, as well as solar curtains, solar umbrellas, solar tents, or applications for the military. Fairbanks and Andrew are not the first to conceive of solar textiles, their collaboration overcomes a manufacturing challenge that Andrew says is slowing the rollout of cheap, consumer friendly solar cells, namely the early integration of technologies emerging from the lab with actual manufacturing processes.

no one out there, there no designer working with a device person trying to do this that us and that what really excites me about this project even today, says Andrew.

With a recent grant funded by the Wisconsin Alumni Research Foundation (WARF) and awarded by UW Madison Office of the Vice Chancellor for Research and Graduate Education, Fairbanks and Andrew have begun experimenting with different ways to create solar textiles.

»I thought that was brilliant. I never would thought of that. If we could literally weave together a solar cell: mind blowing.«

One project has materials science and engineering graduate student Lushuai Zhang using vapor phase chemistry to coat different fabric weave types and structures with a polymer that increases its conductivity. Once the weave is at least 10 times more conductive than it was before cheap jerseys coating, the fabric will act as the bottom electrode on which Zhang will deposit two different dyes and a top electrode the contact between the four deposits making up a complete and functional solar cell.

A second idea grew from Fairbanks knowledge of weaving. Since the four layers of a dye based solar cell actually don need to be placed down in sequence the point being only to create the right contact between the four components Fairbanks suggested they try creating a spool of thread for each of the components. If Fairbanks could then weave those threads together, two electrodes and two dyes, the weave cross sections would also create the contact points necessary for a fully functional device.

thought that was brilliant, Andrew says. never would thought of that. If we could literally weave together a solar cell: mind blowing. We really integrating each step of the process, on the textile side, on the device side. this time next year, Fairbanks and Andrew hope to have developed a prototype using the coating technique as well as proof of concept for what Andrew affectionately calls harebrained weaving idea. Either technique could mean many more years of translating their different disciplinary languages to each other for the purpose of creating usable, even wearable, technologies.
