Stanford engineers invent a solar panel that generates electricity at night

Posted by in categories: particle physics, solar power, space, sustainability

“If you can get up to a watt per square meter, it would be very attractive from a cost perspective,” Assawaworrarit says.

The invention taps into a source of energy that’s easily overlooked

The Earth is constantly receiving a tremendous amount of energy from the Sun, to the tune of 173,000 terrawatts. Clouds, particles in the atmosphere, and reflective surfaces like snow-covered mountains immediately reflect 30 percent of that energy out into space. The rest of it ends up warming the land, oceans, clouds, atmosphere, and everything else on the planet.

Solar cars can reduce global charging needs by half

Posted by in categories: solar power, sustainability, transportation

A new study modeled the behavior of solar vehicles in 100 locations around the world.

According to a new study, solar energy can provide a range of between 6 and 18 miles (11 and 29 kilometers) for electric vehicles each day, cutting down on the requirement for charging by half. The study took into account the capabilities of solar-powered vehicles in urban settings in 100 locations across the world, modeling the behavior of the cars in busy cities.

How long do residential solar batteries last?

Posted by in categories: solar power, sustainability, transportation

In the first and second parts of this series, pv magazine reviewed the productive lifespan of residential solar panels and inverters. Here, we examine home batteries, how well they perform over time, and how long they last.

Residential energy storage has become an increasingly popular feature of home solar. A recent SunPower survey of more than 1,500 households found that about 40% of Americans worry about power outages on a regular basis. Of the survey respondents actively considering solar for their homes, 70% said they planned to include a battery energy storage system.

Besides providing backup power during outages, many batteries are integrated with technology that allows for intelligent scheduling of the import and export of energy. The goal is to maximize the value of the home’s solar system. And, some batteries are optimized to integrate an electric vehicle charger.

A strategy to fabricate highly performing tin perovskite-based transistors

Posted by in categories: computing, solar power, sustainability

Metal halide perovskites are semiconducting materials with advantageous optoelectronic properties, low defects and low costs of production. In contrast with other emerging semiconductors, these materials can be easily synthesized via affordable solution processing methods.

In recent years, some engineers have been exploring the potential of for creating highly solar cells and light emitting diodes (LEDs). Their favorable characteristics, however, could also facilitate their use for fabricating next-generation , including .

Researchers at Pohang University of Science and Technology in South Korea, the Chinse Academy of Sciences and the University of Electronic Science and Technology of China recently introduced a new strategy to develop transistors based on a metal perovskite, specifically tin perovskite. In their paper, published in Nature Electronics, they showed that the resulting tin perovskite-based transistors could attain performances comparable to those of existing .

Scientists synthesize new organometallic ‘sandwich’ compound capable of holding more electrons

Posted by in categories: biotech/medical, chemistry, solar power

Organometallic compounds, molecules made up of metal atoms and organic molecules, are often used to accelerate chemical reactions and have played a significant role in advancing the field of chemistry.

Metallocenes, a type of organometallic compound, are known for their versatility and special “sandwich” structure. Their discovery was a significant contribution to the field of organometallic chemistry and led to the awarding of the Nobel Prize in Chemistry in 1973 to the scientists who discovered and explained their sandwich structure.

The versatility of metallocenes is due to their ability to “sandwich” many different elements to form a variety of compounds. They can be used in various applications, including the production of polymers, glucometers—used to measure the amount of glucose in the blood, perovskite , and as a catalyst, a substance that increases the rate of a chemical reaction without being consumed or changed by the reaction itself.

Scientists use quantum device to slow down simulated chemical reaction 100 billion times

Posted by in categories: chemistry, computing, environmental, quantum physics, solar power

Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times.

Joint lead researcher and Ph.D. student, Vanessa Olaya Agudelo, said, It is by understanding these basic processes inside and between molecules that we can open up a new world of possibilities in , drug design, or harvesting.

Transparent solar panels will soon become a window of energy and light in your home

Posted by in categories: solar power, sustainability

Transparent solar windows are not only generating news as demonstration projects—many have already been set up. On the list of installations for UE Power are its own offices in Redwood City, California, at the R&D facility of its partner in Northwood, Ohio, a commercial office building in Boulder, Colorado, and in Tokyo, Japan. In addition, it has an installation at Michigan State University. UbiQD also claims to have installations in multiple U.S. states, which include a Holiday Inn hotel, its own headquarters in Los Alamos, and the Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden, Colorado.

What’s the premium for transparency?

UbiQD’s product isn’t commercially available yet, but McDaniel expects the premium for transparent solar power to be not more than 30 percent over ordinary windows. He said that “Traditional solar cells are not sold at a cost per watt, not based on area, like windows. The additional window cost, per watt, is similar to utility-scale solar. We have a similar payback time to traditional solar [before incentives].”
