One of the reasons solar cells are not used more widely is cost — the materials used to make them most efficient are expensive. Engineers are exploring ways to print solar cells from inks, but the devices don’t work as well. Elijah Thimsen, PhD, assistant professor of energy, environmental & chemical...

New technique helps probe performance of organic solar cell materials
A research team led by North Carolina State University has developed a new technique for determining the role that a material’s structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The researchers have used the technique to determine that materials with a highly organized structure...
Scientists 'bend' elastic waves with new metamaterials that could have commercial applications
Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered "elastic" waves. These waves travel at the surface or through a material without causing any permanent changes to the substance's makeup. Now, engineering researchers at the University of Missouri have developed...
