Blue-emitting diode demonstrates limitations and promise of perovskite semiconductors

Berkeley CA (SPX) Jan 27, 2020
University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices. In the process, however, the researchers discovered a fundamental property of halide perovskites that may prove a barrier to their widespr

A new stretchable battery can power wearable electronics

Stanford CA (SPX) Jan 26, 2020
Electronics are showing up everywhere: on our laps, in pockets and purses and, increasingly, snuggled up against our skin or sewed into our clothing. But the adoption of wearable electronics has so far been limited by their need to derive power from bulky, rigid batteries that reduce comfort and may present safety hazards due to chemical leakage or combustion. Now Stanford researcher

Nuclear waste turned into ‘near-infinite powerful’ batteries to potentially boost spacecraft might

Bristol UK (SPX) Jan 26, 2020
British university researchers have turned their attention to deserted nuclear power plants and the tonnes of waste they still house despite long ago having closed down. What they have stumbled upon seems to store great potential, even when it comes to space travel. University of Bristol researchers have developed and tested next-generation diamond batteries that exploit energy from radioa

Less may be more in next-gen batteries

Houston TX (SPX) Jan 24, 2020
The process of developing better rechargeable batteries may be cloudy, but there’s an alumina lining. A slim layer of the metal oxide applied to common cathodes by engineers at Rice University’s Brown School of Engineering revealed new phenomena that could lead to batteries that are better geared toward electric cars and more robust off-grid energy storage. The study in the American

TIME Magazine’s Best Inventions of 2019

Each year, TIME solicits nominatinos for the inventions that make the world a smarter and better place. Each submission is evaluated on originality, creativity, influence, ambition and effectiveness. Find out more about three solar pioneers who made the 2019 TIME Top 100 Inventions list using SunPower solar technology.

Spain declares climate emergency, signals move to renewables

Madrid (AFP) Jan 21, 2020
Spain’s new government on Tuesday declared a “climate emergency” and pledged to unveil a draft bill on transitioning to renewable energy within its first 100 days in office. In a statement announced after the weekly cabinet meeting, the government committed to bringing a draft bill “to reduce greenhouse gas emissions with the objective of reaching climate neutrality by 2050” – effectively

New molecule harnesses full visible spectrum of sunlight

Washington DC (UPI) Jan 21, 2020
Scientists have discovered a molecule that can take advantage of the entire visible spectrum of sunlight. The molecule can both efficiently absorb sunlight and operate as a catalyst, triggering the conversion of solar energy into hydrogen, which can be used as fuel. In a new paper, published this week in the journal Nature Chemistry, scientists suggest the novel molecule can be used to

Tests measure solar panel performance beyond established standards

Washington DC (SPX) Jan 07, 2020
Photovoltaics used in solar panels are sensitive to environmental factors and often suffer degradation over time. International Electrotechnical Commission standards for accelerated degradation do not include field tests. While some testing facilities have made data available, much of the data needed to make business decisions for PV is not available publicly. In testing solar panels, the

Qatar signs $470 mn solar deal

Doha (AFP) Jan 19, 2020
Gas-rich Qatar signed a $470-million deal on Sunday to build its first solar energy plant, capable of meeting up to one-tenth of peak national power demand. The Al-Kharsaah plant, near the capital, is a 10-square-kilometre (4-sq-mile) joint venture with French and Japanese partners due for completion in 2022 ahead of the football World Cup. “Eight times the solar power pledged in the Wor

Monash develops world’s most efficient lithium-sulfur battery

Melbourne, Australia (SPX) Jan 07, 2020
Imagine having access to a battery, which has the potential to power your phone for five continuous days, or enable an electric vehicle to drive more than 1000km without needing to “refuel”. Monash University researchers are on the brink of commercialising the world’s most efficient lithium-sulphur (Li-S) battery, which could outperform current market leaders by more than four times, and p
