Photoelectrochemical Cell Captures Excess Photon Energy
GOLDEN, Colo., April 20, 2017 — A proof-of principal photoelectrochemical cell capable of capturing excess photon energy that is normally lost to generating heat could produce solar fuels. Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL)...
NREL Raises Rooftop PV Potential Estimate
WASHINGTON, D.C., April 8, 2016 — The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) said it has used detailed lidar data for 128 cities nationwide, along with improved data analysis methods and simulation tools, to update its estimate of total U.S....
Defects Could Boost Silicon Solar Cell Performance
GOLDEN, Colo., Jan. 22, 2016 — The efficiency of silicon solar cells could be improved by specific defects that boost carrier collection out of the cell or improve passivation of the absorber layer. Scientists at the Energy Department's National Renewable Energy Laboratory (NREL)...
Efficiency Record Set for Tandem Solar Cells
GOLDEN, Colo., Jan. 7, 2016 — A dual-junction semiconductor solar cell has overcome a theoretical limit to take a world record for efficiency — 29.8 percent. The device consists of a GaInP top cell developed at the National Renewable Energy Laboratory (NREL) and a...
Spectroscopic Probe Monitors Photoconversion Process
GOLDEN, Colo., Dec. 10, 2015 — A measurement probe could lead to improvements in how photoelectrodes are designed, making them more efficient and stable. Photoelectrochemical cells can be used to convert solar energy into transportable chemical fuels. The photoconversion process...
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...
Manufacturers Refocus Technology Efforts Following Recent Financial Woes
Mar 7, 2014 — Overcapacity has caused financial problems in the past few years, so the solar industry has been somewhat less focused on implementing technology advances - but today things are looking up and research is being rivived. The solar market was...
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.
Optical Cavity Furnace Could Cut Solar Costs
GOLDEN, Colo., Oct. 26, 2011 — A new furnace system for manufacturing solar cells has been developed — an advance that could boost efficiency and cut the cost of producing solar panels in the future. The Optical Cavity Furnace (OCF) is designed to replace the standard...
Silicon Ink Is Useful in Solar Cells
SUNNYVALE, Calif., Oct. 11, 2011 — A special ink that can suspend silicon nanoparticles evenly in a solution is proving useful in solar cell production. The silicon ink can lay down precise microns-thick lines that are needed to dope the silicon emitter exactly under the front metal...
GE to Build US Solar Panel Factory
Jul 1, 2011 — GE announced that its full-size cadmium telluride thin-film solar panel has been independently certified as the most efficient ever reported for the technology. The company intends to manufacture the panels at a new 400-MW US factory as part of a...
GE to Build US Plant as Part of $600M Solar Investment
ARVADA, Colo., May 9, 2011 — GE announced that its full-size cadmium telluride thin-film solar panel has been independently certified as the most efficient ever publicly reported for the technology. The company said it intends to manufacture the panels at a new 400-MW US...
Painting the roof with solar ink
Nov 1, 2009 — Covering rooftops with solar cells came one step closer to reality recently when JA Solar of Yangzhou, China, announced plans to commercialize technology developed by Innovalight, a San Francisco Bay-area company that makes a silicon solar...
The road to solar cell supremacy
Oct 1, 2009 — The silicon traditionally used to make solar panels is costly and inefficient at converting sunlight into electricity, experts say, yet it remains the material most commonly used to make solar panels. “This sounds rather ugly, but silicon is the...
13 Solar Energy Projects to Receive up to $168M from DoE
WASHINGTON, March 13, 2007 -- US Department of Energy (DoE) Secretary Samuel W. Bodman announced last week the selection of 13 industry-led solar technology development projects to negotiate with the department for as much as $168 million in federal funding for FY 2007-09. Once...
