Theoretically, two layers are better than one for solar-cell efficiency
15 Sep 2020 at 4:42pm
Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind more expensive, crystalline solar cells in efficiency. Now, a team of researchers suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency.
California offshore winds show promise as power source
8 Sep 2020 at 2:05pm
One of the challenges of moving toward fully renewable energy in California by 2045 is matching production to demand. Consumer demand peaks in the evening when solar energy is no longer available. Offshore wind energy has the potential to help meet this demand.
Battery-free Game Boy runs forever
3 Sep 2020 at 2:14pm
Researchers develop first-ever battery-free, energy-harvesting, interactive device. And it looks and feels like a retro 8-bit Nintendo Game Boy.
New understanding of electrolyte additives will improve dye-sensitized solar ...
3 Sep 2020 at 6:56am
Dye-sensitised solar cells could perform better thanks to improved understanding of additives in optimizing electrolytes. Researchers have determined that the molecules 4-tert-butylpyridine (tBP) and 1-methyl-benzimidazole (NMBI) can play an integral role in suppressing recombination losses and maximizing efficiency.
Molecule to store solar energy developed
31 Aug 2020 at 9:42am
Researchers have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption.
New insights for sun-gathering technologies
24 Aug 2020 at 11:44am
Researchers are taking a page from Nature's lesson book. Inspired by the way plants and other photosynthetic organisms collect and use the sun's radiant energy, they hope to develop technologies that harvest sunlight and store it as carbon-free or carbon-neutral fuels.
Wireless device makes clean fuel from sunlight, CO2 and water
24 Aug 2020 at 9:34am
Researchers have developed a standalone device that converts sunlight, carbon dioxide and water into a carbon-neutral fuel, without requiring any additional components or electricity.
Large tin monosulfide crystal opens pathway for next generation solar cells
21 Aug 2020 at 6:48am
A team has succeeded in growing large single crystals of tin monosulfide, a material used in next generation solar cells.
Climate change impact on green energy production
18 Aug 2020 at 8:49am
As the climate of the planet is changing, many researchers are looking to more renewable energy sources. Researchers investigate whether the power generated by solar and wind farms would differ between current and future climates. The researchers focused on sites in Australia where variable renewable generators are located or are likely to be located in the future based on the Australian Energy Market Operator's system plan.
Transparent solar panels for windows hit record 8 percent efficiency
17 Aug 2020 at 12:04pm
In a step closer to skyscrapers that serve as power sources, researchers have set a new efficiency record for color-neutral, transparent solar cells.
Converting solar energy to hydrogen fuel, with help from photosynthesis
17 Aug 2020 at 7:43am
Global economic growth comes with increasing demand for energy, but stepping up energy production can be challenging. Recently, scientists have achieved record efficiency for solar-to-fuel conversion, and now they want to incorporate the machinery of photosynthesis to push it further.
Efficient low-cost system for producing power at night
13 Aug 2020 at 12:22pm
Researchers have designed an off-grid, low-cost modular energy source that can efficiently produce power at night. The system uses commercially available technology and could eventually help meet the need for nighttime lighting in urban areas or provide lighting in developing countries.
Perovskite and organic solar cells rocketed into space
12 Aug 2020 at 8:53am
Researchers have sent perovskite and organic solar cells on a rocket into space. The solar cells withstood the extreme conditions in space, producing power from direct sunlight and reflective light from the Earth's surface. The work sets the foundation for future near-Earth application as well as potential deep space missions.
Countries transitioning to zero carbon should look at more than technology cost
12 Aug 2020 at 8:53am
A 'one-size-fits-all' approach to producing cleaner energy based on cost alone could create social inequalities, finds a new study.
Molecular additives enhance mechanical properties of organic solar cell material
12 Aug 2020 at 6:48am
Computational experiments on semiconducting polymers show that under harsh loading conditions -- stretching and compression -- the addition of small molecules enhances performance and stability. The research points to a promising new direction for solar cell research.
