Perovskite solar cells made with peppermint oil and walnut aroma food additiv...
26 Feb 2020 at 7:21am
Engineers have developed eco-friendly-solvent processable hole transport polymers by using peppermint oil and walnut aroma food additives and the polymer can prevent lead leakage.
Scientists develop safer lead-based perovskite solar cell
19 Feb 2020 at 12:44pm
Researchers are reporting on a potential breakthrough in the development of hybrid perovskite solar cells. The scientists developed a technique to sequester the lead used to make perovskite solar cells and minimize potential toxic leakage.
New world record for conversion of solar energy to electricity using quantum ...
18 Feb 2020 at 3:22pm
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
12 Feb 2020 at 12:01pm
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 sol...
10 Feb 2020 at 7:41am
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
7 Feb 2020 at 9:44am
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
7 Feb 2020 at 9:37am
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
4 Feb 2020 at 9:57am
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
29 Jan 2020 at 2:45pm
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
28 Jan 2020 at 8:47am
Researchers have outlined a pathway to slashing costs further, this time by slimming down the silicon cells themselves.
Researchers advance solar material production
27 Jan 2020 at 10:48am
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
21 Jan 2020 at 8:29am
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 bette...
15 Jan 2020 at 9:06am
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?
13 Jan 2020 at 4:58am
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
9 Jan 2020 at 11:09am
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.
