New world record for conversion of solar energy to electricity using quantum dots
Tue, 18 Feb 2020 18:22:08 EST
Researchers have set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called 'quantum dots'. The technology has a huge range of potential applications, including the possibility to use it as a flexible, transparent skin to power cars, planes, homes and wearable technology.
Cracks in perovskite films for solar cells easily healed, study finds
Wed, 12 Feb 2020 15:01:51 EST
A new study finds that cracks in brittle perovskite films can be easily healed with compression or mild heating, a good sign for the use of perovskites in next-generation solar cells.
Oblique electrostatic inject-deposited TiO2 film for efficient perovskite solar cells
Mon, 10 Feb 2020 10:41:24 EST
The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites -- materials with a particular crystal structure -- is now competing with conventional silicon materials to satisfy the demand in this area. Perovskite solar cells (PSCs) are continually being optimized to fulfill their commercial potential.
Simple, solar-powered water desalination
Fri, 07 Feb 2020 12:44:56 EST
A completely passive solar-powered desalination system 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.
Next generation of greenhouses may be fully solar powered
Fri, 07 Feb 2020 12:37:59 EST
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.
Lasers etch a 'perfect' solar energy absorber
Tue, 04 Feb 2020 12:57:11 EST
Researchers demonstrate how laser etching of metallic surfaces creates the ''perfect solar energy absorber.'' This not only enhances energy absorption from sunlight, but also reduces heat dissipation at other wavelengths. The researchers also demonstrate solar energy harnessing with a thermal electric generator.
Anti-solar cells: A photovoltaic cell that works at night
Wed, 29 Jan 2020 17:45:12 EST
What if solar cells worked at night? That's no joke. In fact, a specially designed photovoltaic cell could generate up to 50 watts of power per square meter under ideal conditions at night, about a quarter of what a conventional solar panel can generate in daytime, according to a recent concept article.
For cheaper solar cells, thinner really is better
Tue, 28 Jan 2020 11:47:22 EST
Researchers have outlined a pathway to slashing costs further, this time by slimming down the silicon cells themselves.
Researchers advance solar material production
Mon, 27 Jan 2020 13:48:15 EST
A team has developed a more efficient, safer, and cost-effective way to produce cadmium telluride (CdTe) material for solar cells or other applications, a discovery that could advance the solar industry and make it more competitive.
Plants absorb lead from perovskite solar cells more than expected
Tue, 21 Jan 2020 11:29:45 EST
Lead from metal-organic perovskite compounds can be absorbed particularly easily by plants. The bioavailability is significantly higher than that of lead from inorganic compounds as found in batteries.
New study on a recently discovered chlorophyll molecule could be key to better solar cells
Wed, 15 Jan 2020 12:06:24 EST
Photosynthesis, the process by which some organisms convert sunlight into chemical energy, is well known. But, it is a complex phenomenon, which involves a myriad of proteins. The molecule Chl f, a new type of chlorophyll, is known to play a part in photosynthesis, but owing to its recent discovery, its location and functions are not understood. Scientists have now analyzed in detail the protein complex involved in photosynthesis and uncovered several new aspects about Chl f.
Can solar geoengineering mitigate both climate change and income inequality?
Mon, 13 Jan 2020 07:58:28 EST
New research finds that solar geoengineering -- the intentional reflection of sunlight away from the Earth's surface -- may reduce income inequality between countries.
Growing strained crystals could improve performance of perovskite electronics
Thu, 09 Jan 2020 14:09:32 EST
A new method could enable researchers to build more efficient, longer lasting perovskite solar cells and LEDs. By growing thin perovskite films on different substrates, engineers invented a way of fabricating perovskite single crystals with precisely deformed, or strained, structures.
Tests measure solar panel performance beyond established standards
Thu, 02 Jan 2020 18:48:34 EST
In testing solar panels, the sun's intensity, the spectral composition and the angle of light are important factors in understanding why certain panels are successful and others degrade more quickly. To address the knowledge gap in degradation mechanisms for various photovoltaic types, researchers performed tests over five years in which they collected weather data and panel performance information.
Tweaks behind the rebirth of nearly discarded organic solar technologies
Thu, 19 Dec 2019 12:25:14 EST
A minuscule chemical tweak is advancing an organic solar technology that was once thought unviable.
Solar power from 'the dark side' unlocked by a new formula
Wed, 18 Dec 2019 15:35:56 EST
Most of today's solar panels capture sunlight and convert it to electricity only from the side facing the sky. If the dark underside of a solar panel could also convert sunlight reflected off the ground, even more electricity might be generated.
