A new miniature solution for storing renewable energy
12 Oct 2017 at 7:38am
In a first for metal-organic frameworks, scientists have demonstrated their metallic conductivity.
Mimicking two natural energy processes with a single catalyst
11 Oct 2017 at 7:07am
Researchers take inspiration from natural chemical processes based on hydrogenase and photosystem II, to produce a single metal catalyst with both fuel cell and solar cell functionalities. The combination of these two processes into one system suggests great potential for biologically inspired energy generation technologies.
Solar-powered devices made of wood could help mitigate water scarcity crisis
10 Oct 2017 at 7:45pm
Energy from the sun and a block of wood smaller than an adult's hand are the only components needed to heat water to its steaming point in these purifying devices.
Solar energy: Prototype shows how tiny photodetectors can double their effici...
9 Oct 2017 at 9:32am
Physicists have developed a photodetector -- a device that converts light into electrons -- by combining two distinct inorganic materials and producing quantum mechanical processes that could revolutionize the way solar energy is collected. The researchers stacked two atomic layers of tungsten diselenide on a single atomic layer of molybdenum diselenide. Such stacking results in properties vastly different from those of the parent layers, allowing for customized electronic engineering at the tiniest possible scale.
New nanomaterial can extract hydrogen fuel from seawater
4 Oct 2017 at 1:20pm
A new hybrid nanomaterial harvests solar energy and uses it to extract hydrogen from seawater, cheaply and efficiently. Future commercialization could mean a new source of environmentally friendly fuel and less dependence on fossil fuels.
Perovskite solar cells reach record long-term stability, efficiency over 20 p...

Scientists have greatly improved the operational stability of perovskite solar cells by introducing cuprous thiocyanate protected by a thin layer of reduced graphene oxide. Devices lost less than 5 percent performance when subjected to a crucial accelerated aging test during which they were exposed for more than 1,000 hours to full sunlight at 60°C.
Energy harvested from evaporation could power much of US
26 Sep 2017 at 9:51am
In the first evaluation of evaporation as a renewable energy source, researchers find that US lakes and reservoirs could generate 325 gigawatts of power, nearly 70 percent of what the United States currently produces.
Wearable solar thermoelectric generator created
26 Sep 2017 at 7:55am
Engineers have introduced a new advanced energy harvesting system, capable of generating electricity by simply being attached to clothes, windows, and outer walls of a building.
Fully renewable India in 2050 can take a shortcut to emission-free future
25 Sep 2017 at 8:16am
India can function on a fully renewable electricity system in 2050, research indicates. The study shows that developing countries that have an abundance of renewable resources do not need to take the path of the western countries where increasing living standards have been coupled with heavy emissions from electricity generation and other industry. They can move straight to renewable systems and do it cheaply.
Semitransparent and flexible: Solar cells made from atomically thin sheet
25 Sep 2017 at 6:55am
A new method for fabricating semitransperant, flexible solar cells has greatly improved power conversion efficiency.
Astonishing time limit for ultrafast perovskite solar cells set
21 Sep 2017 at 7:17am
Researchers have quantified the astonishingly high speeds at which future solar cells would have to operate in order to stretch what are presently seen as natural limits on their energy conversion efficiency.
Solar-to-fuel system recycles CO2 to make ethanol and ethylene
18 Sep 2017 at 12:17pm
Scientists have harnessed the power of photosynthesis to convert carbon dioxide into fuels and alcohols at efficiencies far greater than plants. The achievement marks a significant advance in the effort to move toward sustainable sources of fuel.
Coatings needed for concentrating solar power
18 Sep 2017 at 12:17pm
Next-generation concentrating solar power (CSP) plants require high-temperature fluids, like molten salts, in the range of 550-750 degrees Celsius to store heat and generate electricity. At those high temperatures, however, the molten salts eat away at common alloys used in the heat exchangers, piping, and storage vessels of CSP systems. New research is aimed at mitigating corrosion levels in CSP plants with nickel-based coatings.
A solar cell you can put in the wash
18 Sep 2017 at 8:18am
Scientists have developed a new type of ultra-thin photovoltaic device, coated on both sides with stretchable and waterproof films, which can continue to provide electricity from sunlight even after being soaked in water or being stretched and compressed.
Hydrogen power moves a step closer
14 Sep 2017 at 12:22pm
Physicists are developing methods of creating renewable fuel from water using quantum technology. Renewable hydrogen can already be produced by photoelectrolysis where solar power is used to split water molecules into oxygen and hydrogen. But fundamental problems remain before this can be adopted commercially due to inefficiency. A new study demonstrates that the novel use of nanostructures could increase the maximum photovoltage generated in a photoelectrochemical cell, increasing the productivity of splitting water molecules.
