Revealing the hidden path of perovskite formation

Lausanne, Switzerland (SPX) Feb 08, 2018
Perovskite solar cells are an alternative to conventional silicon solar cells, poised to enter the market with their high power-conversion efficiencies (above 22% now) and lower capital expenditure and manufacturing costs. One of the main methods for depositing perovskite films onto panel structures is a process known as sequential deposition reaction, which was developed in 2013 by Michae

Production of solar fuels inches closer with discovery by Caltech scientists

Pasadena CA (SPX) Feb 08, 2018
Caltech researchers have made a discovery that they say could lead to the economically viable production of solar fuels in the next few years. For years, solar-fuel research has focused on developing catalysts that can split water into hydrogen and oxygen using only sunlight. The resulting hydrogen fuel could be used to power motor vehicles, electrical plants, and fuel cells. Since the onl

Monitoring positive charges in solar materials

Lausanne, Switzerland (SPX) Feb 08, 2018
Transition metal oxides such as Zinc Oxide (ZnO) are at the center of the recent surge in research and development on solar energy conversion into electrical (photovoltaics) or chemical (photocatalytic) forms, but also of applications such as detectors of high-energy radiation. All of these applications rely on the generation of negative (electrons) and positive (holes) charges, and the un

NREL scientists demonstrate remarkable stability in perovskite solar cells

Golden CO (SPX) Feb 08, 2018
Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) created an environmentally stable, high-efficiency perovskite solar cell, bringing the emerging technology a step closer to commercial deployment. Over the past decade, perovskites have rapidly evolved into a promising technology, now with the ability to convert about 23 percent of sunlight into elec

New approach could quickly identify best organic solar cell mixtures

Raleigh NC (SPX) Feb 08, 2018
An international team of researchers has discovered a new quantitative relation that allows for quick identification of promising material combinations for organic solar cells. The discovery could significantly reduce the "trial and error" aspect of solar cell production by reducing the time spent on finding the most efficient mixtures. The research appears in Nature Materials. Presently,

Scientists discover material ideal for smart photovoltaic windows

Berkeley CA (SPX) Jan 05, 2018
Smart windows that are transparent when it's dark or cool but automatically darken when the sun is too bright are increasingly popular energy-saving devices. But imagine that when the window is darkened, it simultaneously produces electricity. Such a material - a photovoltaic glass that is also reversibly thermochromic - is a green technology researchers have long worked toward, and now, scienti

Cal Poly dedicates 4.5 Megawatt solar farm

San Luis Obispo CA (SPX) Feb 05, 2018
Cal Poly's new solar farm, the university's first major energy project since announcing a goal of climate neutrality, was dedicated at a Wednesday, Jan. 24, ceremony at the site. The 18.5-acre solar farm will generate more than 11 million kWh per year - enough to power more than 1,000 homes, or about 25 percent of Cal Poly's total needs - and includes more than 16,000 individual solar panels wit

U.S. tariff on solar power components met with backlash

Washington (UPI) Jan 23, 2018
A U.S. decision to impose import tariffs on solar power equipment means Asian manufactures may simply shift focus to expanding Asian markets, analysis found. U.S. Trade Representative Robert Lighthizer said Monday that President Donald Trump imposed "safeguard tariffs" on imported solar cells and modules because of complaints those imports caused serious harm to domestic manufacturers.

Colorado updates clean energy vision

Washington (UPI) Feb 1, 2018
Building on executive actions from July, Colorado's governor revised the state climate plan to include emissions abatement and an electric vehicle corridor. Gov. John Hickenlooper in July outlined a mandate to cut state-wide greenhouse gas emissions by more than 25 percent from their 2005 levels and cut the emissions of carbon dioxide, a potent greenhouse gas, from the electricity secto

China hits back after US tariffs

Beijing (AFP) Feb 5, 2018
China has launched an anti-dumping investigation into sorghum imports from the United States, spurring worries of a brewing tit-for-tat trade war between the world's top two economies. The commerce ministry announced the self-initiated probe on Sunday, just weeks after President Donald Trump's administration slapped its latest batch of tariffs on Chinese goods. The ministry did not immed

A simple new approach to plastic solar cells

Osaka, Japan (SPX) Jan 29, 2018
Humankind is in the midst of a massive drive to harness solar energy to power our homes, gadgets, and industry. Plastic solar cells, based on blends of conducting organic polymers, are of interest for making lightweight and cheap solar cells. The problem with these kinds of solar cells is that their solar power efficiencies are very closely related to the way the different types of materials mix

Kyocera team update progress of 480-Megawatt solar power project

Tokyo, Japan (SPX) Feb 05, 2018
Kyocera Corporation, Kyudenko Corporation, and Mizuho Bank, Limited which have been jointly investigating the possibility of operating a maximum 480-megawatt (MW) solar power project on the island of Ukujima (Sasebo City, Nagasaki Pref., Japan) since June 2014, have announced that the project has entered a new phase with the inclusion of five other participants: SPCG Public Company Limited, Toky

Tesla, Australia to turn 50,000 homes into power generators

Sydney (AFP) Feb 4, 2018
Some 50,000 homes in South Australia will receive solar panels and Tesla batteries, the state government announced Sunday, in a landmark plan to turn houses into a giant, interconnected power plant. South Australia is already home to world's biggest battery in an Elon Musk-driven project to provide electricity for more than 30,000 homes. The state government has since been looking for mo

White House seeking to slash renewable energy research: report

Washington (AFP) Jan 31, 2018
The Trump administration will ask Congress to cut funding for clean energy and energy efficiency programs by 72 percent in this year's budget, according to a report in the Washington Post, underscoring its preference for fossil fuels. The Post said it had obtained draft documents that outlined the administration's starting point for negotiations for the 2018 budget, set to be unveiled in Feb
