A solar-powered unmanned aircraft with a wingspan of 114 feet completed its maiden high-altitude flight in the stratosphere, maker BAE Systems said on Monday. The plane, called PHASA-35, which stands for Persistent High altitude Solar Aircraft and its wingspan measured in meters, is meant to fly about 32 miles above the earth in the space, in the upper atmosphere between conventional...

Hunt Energy announced reports that its solar technology company, Hunt Perovskite Technologies (HPT), has achieved an industry-leading milestone in the development of a highly-durable perovskite technology for the manufacture of low-cost printed solar cells. In December 2019, HPT successfully demonstrated that its ink-based process was able to produce a perovskite solar cell that exceeded...

Organic photovoltaic (OPV) cells have attracted considerable research interest because of advantages of lightweight, flexibility and low-cost solution processing. With the development of organic photoactive materials, especially the new-emerging non-fullerene electron acceptors (NFAs), OPV cells have yielded power conversion efficiencies (PCEs) of over 16% in recent years. However, these devices...

A new study reveals good news for the possibility of using perovskite materials in next-generation solar cells. The study, published in the journal Acta Materialia, finds that though perovskite films tend to crack easily, those cracks are easily healed with some compression or a little bit of heat. That bodes well, the researchers say, for the use of inexpensive perovskites to replace or...

Contrary to theoretical predictions, oxygen inactivates biocatalysts for energy conversion within a short time, even under a protective film. A research team of the Resolv Cluster of Excellence at Ruhr Universitat Bochum (RUB) has found out why: Hydrogen peroxide forms on the protective film. The addition of iodide salts to the electrolyte can prevent this from happening and considerably...

Many greenhouses could become energy neutral by using see-through solar panels to harvest energy - primarily from the wavelengths of light that plants don't use for photosynthesis. Those are the findings of a new modeling study conducted by engineering, plant biology and physics researchers at North Carolina State University...

A completely passive solar-powered desalination system developed by researchers at MIT and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source. The system uses multiple layers of flat solar evaporators and...

Cities have played a key role in the rise of renewable energy, especially solar and wind, due to building energy codes and benchmarking policies.

Dozens of chargers will allow drivers to charge their electric vehicle while parked in the utility's New York City service territory — though they will likely pay more than equivalent gasoline costs.

The utility will work with Advanced Energy Economy and 13 companies to develop clean energy solutions that include electrifying transportation, grid flexibility and expanding low-carbon generation capacity.

Despite growing concerns that "bullish" utility investments in natural gas may lead to stranded assets amid rapid decarbonization, just 18% of utility employees surveyed by Utility Dive view those risks as a top concern.

The Virginia Clean Economy Act gives the state extra powers to potentially block new natural gas-fired power plants.

Experts warn that cyber standards compliance is not synonymous with security, as Utility Dive's annual survey shows that less than 60% "believe their organization is in or approaching compliance with government cybersecurity mandates."
