Made from Solar Concentrate

Bathing the Earth with enough energy in one hour to meet human needs for an entire year, the sun represents the ultimate source of clean, green sustainable energy.

A team of scientists with Berkeley Lab and the University of Illinois created solar cells that collect higher energy photons at 30 times the concentration of conventional solar cells, the highest luminescent concentration factor ever recorded.

Soaking Up Carbon Dioxide and Turning it into Valuable Products

Structural model showing a covalent organic framework (COF)  embedded with a cobalt porphyrin.

Berkeley Lab researchers have incorporated molecules of porphyrin CO2 catalysts into the sponge-like crystals of covalent organic frameworks (COFs) to create a molecular system that not only absorbs CO2, but also selectively reduces it to CO, a primary building block for a wide range of chemical products.

Another Milestone in Hybrid Artificial Photosynthesis

Peidong Yang CJC Bioinorganic Solar to Chemical Text

Berkeley Lab researchers using a bioinorganic hybrid approach to artificial photosynthesis have combined semiconducting nanowires with select microbes to create a system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.

The installed price of distributed solar photovoltaic (PV) power systems in the United States continues to fall precipitously. This is according to the latest edition of Tracking the Sun, an annual PV cost tracking report produced by Berkeley Lab.

Berkeley Lab Study Finds that Future Deployment of Distributed Solar Hinges on Electricity Rate Design

Future distributed solar photovoltaic (PV) deployment levels are highly sensitive to retail electricity rate design, according to a newly released report by researchers from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). The study also explores the feedback effects between retail electricity rates and PV deployment, and suggests that increased solar deployment can lead to changes in PV compensation levels that either accelerate or dampen further deployment.

Orange is the New Red

Berkeley Lab researchers discovered that a photoprotective mechanism in cyanobacteria is triggered by an unprecedented, large-scale movement from one location to another of the carotenoid pigment within the Orange Carotenoid Protein.

The Future of Energy Looks Bright at Berkeley Lab

Chu Hall, Berkeley Lab

The Solar Energy Research Center (SERC), renamed to Chu Hall, opened today at Berkeley Lab. It will house laboratories and offices devoted to photovoltaic and electro-chemical solar energy systems designed to improve on what plants do and make transportation fuels. The building houses the lab’s programs in the Joint Center for Artificial Photosynthesis (JCAP) and the Kavli Energy NanoSciences Institute . The three-story, nearly 40,000 square-foot, building cost $59 million will house approximately 100 researchers and was named after former Berkeley Lab Director Steven Chu, who went on to become U.S. Energy Secretary.

Berkeley Lab Illuminates Price Premiums for U.S. Solar Home Sales

A multi-institutional research team of scientists led by Berkeley Lab, in partnership with Sandia National Laboratories, universities, and appraisers found that home buyers consistently have been willing to pay more for homes with host-owned solar photovoltaic (PV) energy systems . The team analyzed almost 22,000 sales of homes, almost 4,000 of which contained PV systems in eight states from 1999 to 2013—producing the most authoritative estimates to date of price premiums for U.S. homes with PV systems.

Berkeley Lab Report Quantifies the Financial Impacts of Customer-Sited Photovoltaics on Electric Utilities

solar-panels-1024x682

A new report prepared by analysts from Berkeley Lab examines the potential impacts of customer-sited solar photovoltaics (PV) on electric utility profitability and rates. The report shows that these impacts can vary greatly depending upon the specific circumstances of the utility and may be reduced through a variety of regulatory and ratemaking measures.
