A new material design tested in experiments at the Department of Energy's SLAC National Accelerator Laboratory could make low-cost solar panels far more efficient by greatly enhancing their ability to collect the sun's energy and release it as electricity.

A team of University of California, Los Angeles, scientists found that by assembling the components of the panels to more closely resemble the natural systems plants use to tap the sun's energy, it may be possible to separate positive and negative charges in a stable way for up to several weeks compared to just millionths of a second -- the current standard for many modern solar panels.

"In photosynthesis, plants that are exposed to sunlight use carefully organized nanoscale structures within their cells to rapidly separate charges -- pulling electrons away from the positively charged molecule that is left behind, and keeping positive and negative charges separated," said Sarah Tolbert, a UCLA professor of chemistry and one of the senior authors of the research. "That separation is the key to making the process so efficient."

Producing the solar panels, need to have some kinds of ingot furnace, need to purchase carbon carbon bolt and nut, carbon carbon profile, and some thermal insulation materials.
