Coming Soon: Printable, Paintable Solar Cells

ScienceDaily (Aug. 25, 2009) — Solar cells could soon be produced more cheaply using nanoparticle “inks” that allow them to be printed like newspaper or painted onto the sides of buildings or rooftops to absorb electricity-producing sunlight.

Brian Korgel, a University of Texas at Austin chemical engineer, is hoping to cut costs to one-tenth of their current price by replacing the standard manufacturing process for solar cells – gas-phase deposition in a vacuum chamber, which requires high temperatures and is relatively expensive.

His team has developed solar-cell prototypes with efficiencies at one percent; however, they need to be about 10 percent.

He also said that the inks, which are semi-transparent, could help realize the prospect of having windows that double as solar cells.
