‘Greener’ way to assemble materials for solar applicationsOctober 8, 2015

Polymers used in solar cells today require solvents that can harm the environment, but scientists using the Advanced Photon Source at Argonne have found a “greener” way to control the assembly of photovoltaic polymers in water using a surfactant— a detergent-like molecule—as a template.

SunShot Initiative award funds scaleup of Argonne’s leading-edge thermal energy storage systemSeptember 16, 2015

On September 16, 2015, the U.S. Department of Energy SunShot Initiative program announced funding awards to several research projects that aim to make concentrating solar power (CSP) plants cost competitive with traditional forms of electricity.

Perovskite solar technology shows quick energy returnsJuly 17, 2015

Silicon-based solar panels, which dominate the market for solar power, usually need about two years to “pay back” the energy used to make them. But for technology made with perovskites—a class of materials causing quite a buzz in the solar research community—the energy payback time is only two to three months.
