Earth Anticipates a Circular Economy for Energy Materials
One of the three key pillars of NREL's vision for the next decade is developing a circular economy for energy materials. This critical objective focuses on reducing waste and preserving resources through the design and manufacture of materials and products with reuse, recycling, and upcycling in mind from the start.
Ten Innovative Teams Emerge Victorious in Round 4 of the American-Made Solar Prize
On April 9, 2021, the U.S. Department of Energy announced 10 finalist teams that are moving forward in the American-Made Solar Prize Round 4 competition.
What It Takes To Realize a Circular Economy for Solar Photovoltaic System Materials
In a series of three reports, NREL analysts examine options and opportunities to repair, reuse, or recycle solar photovoltaic system materials, moving toward a circular economy.
Scientists Studying Solar Try Solving a Dusty Problem
The accumulation of dust, soot, or other particulates causes a drop in the efficiency of solar panels, which translates to a decline in the amount of power produced and lost income for their operators.

Giving Kids the Building Blocks To Envision a Solar Future
As part of NREL's InSPIRE Project, NREL senior analyst Jordan Macknick helped dream up a LEGO solar farm design to educate about energy, water, and food.
New Perovskite Design Shows Path to Higher Efficiency
The new architecture for the cells increases the area exposed to the sun by putting the metal contact layers side by side on the back of the cell.
News Release: New Perovskite LED Emits a Spin-Polarized Glow
The inclusion of a special new perovskite layer has enabled scientists to create a "spin-polarized LED" without needing a magnetic field or extremely low temperatures, potentially clearing the path to a raft of novel technologies.
NREL's New Solar TRACE Tool Adds Transparency to Permitting, Inspection, and Interconnection Nationwide
In partnership with the solar industry, NREL recently developed Solar TRACE, an online tool to increase transparency into PII processes, requirements, and overall adoption cycle times nationwide.
