Perovskite-Based Solar Cells Gaining in Efficiency
GOLDEN, Colo., April 29, 2014 — Perovskites are showing promise as materials for a new generation of highly efficient, low-cost solar cells. A team from the US Energy Department’s National Renewable Energy Laboratory (NREL) is studying the perovskite (CH3NH3)PbI3 to...
Better Materials Mean Better Solar Cells
Sep 1, 2013 — Innovation in materials research is revealing a future in which solar power is inexpensive and efficient, and sunlight-harvesting thin films cover everything from airplanes to buildings. Crystalline silicon, or c-Si, is the dominant photon-absorbing...
Device Tosses Out Unusable PV Wafers
GOLDEN, Colo., Jan. 16, 2013 — Manufacturers need better, less expensive ways to make photovoltaics, and now a solar furnace that kicks out unusable silicon wafers before they become solar cells could potentially save the industry billions of dollars annually.
$125M US-India Initiative Drives WUSTL Solar Expansion
ST. LOUIS, July 25, 2012 — As part of the $125 million US-India Initiative for Clean Energy announced this year, engineers at Washington University in St. Louis will work on low-cost solar cells as well as systems that integrate solar cells with batteries. The technology is...
Consortium Grants $7M to Lower Cost of Large-Scale Solar
STANFORD, Calif., May 21, 2012 — The Bay Area Photovoltaic Consortium, an industry-supported program led by Stanford University and the University of California, Berkeley, received its first research grants aimed at making utility-scale solar power cost-competitive by the end of...
Lasers Change the Shape of the Photovoltaics Industry
Mar 1, 2012 — Laser technology and photovoltaics manufacturing make naturally happy partners. Lasers lend themselves well to the needs of PV development such as drilling, trenching, ablation, welding and doping. Lasers may have been made for photovoltaics...
