Solar cells with 30-year lifetimes for power-generating windows
14 Sep 2021 at 8:12am
A new transparency-friendly solar cell design could marry high efficiencies with 30-year estimated lifetimes, new research has shown. It may pave the way for windows that also provide solar power.
Time to shine: Scientists reveal at an atomic scale how chlorine stabilizes n...
10 Sep 2021 at 9:16am
Researchers have imaged the atoms at the surface of the light-absorbing layer in a new type of next-generation solar cells, made from a crystal material called metal-halide perovskite. Their findings have solved a long-standing mystery in the field of solar power technology, showing how power-boosting and stability-enhancing chlorine is incorporated into the perovskite material.
Combining sunlight and wastewater nitrate to make the world?s No. 2 chemical
8 Sep 2021 at 3:05pm
Engineers have created a solar-powered electrochemical reaction that not only uses wastewater to make ammonia -- the second most-produced chemical in the world -- but also achieves a solar-to-fuel efficiency that is 10 times better than any other comparable technology.
Turning thermal energy into electricity
30 Aug 2021 at 11:02am
With the addition of sensors and enhanced communication tools, providing lightweight, portable power has become even more challenging. New research demonstrated a new approach to turning thermal energy into electricity that could provide compact and efficient power.
Polymer scientist helps develop new technique for large-scale energy storage
19 Aug 2021 at 9:52am
Electric vehicles require power to be available anywhere and anytime without delay to recharge, but solar and wind are intermittent energy sources that are not available on demand. And the electricity they do generate needs to be stored for later use and not go to waste. New research reveals a more stable way to store this important energy.
Common solar tech can power smart devices indoors
19 Aug 2021 at 7:27am
Any time you turn on a light at home or in the office, you are expending electrical energy. But what if flipping the light switch meant providing other useful energy too? We usually think of solar, or photovoltaic (PV), cells fixed to roofs, converting sunlight into electricity, but bringing that technology indoors could further boost the energy efficiency of buildings and energize swaths of wireless smart technologies such as smoke alarms, cameras and temperature sensors, also called Internet of Things (IoT) devices. Now, a new study suggests that a straightforward approach for capturing light indoors may be within reach.
Combining perovskite with silicon, solar cells convert more energy from sun
17 Aug 2021 at 8:14am
To fully harness the potential of sunlight, scientists have been trying to maximize the amount of energy that can be extracted from the sun. Researchers now describe how pairing metal halide perovskites with conventional silicon leads to a more powerful solar cell that overcomes the 26% practical efficiency limit of using silicon cells alone. Perovskites fulfill all the optoelectronic requirements for a photovoltaic cell, and they can be manufactured using existing processes.
New clean energy tech extracts twice the power from ocean waves
17 Aug 2021 at 7:27am
New prototype tech can double the power harvested from ocean waves, an advance that could finally make wave energy a viable renewable alternative.
Enabling the next generation of organic solar cells
11 Aug 2021 at 10:15am
Researchers have discovered a new, faster way in which organic materials redistribute sunlight energy, which could enable the next generation of organic solar cells to convert sunlight into electrical power and help in the battle against climate change.
Powering navigational buoys with help of ocean waves
4 Aug 2021 at 6:01pm
Traditionally used energy harvesting technologies, like photovoltaic panels or wind turbines, suffer from several limitations. In the absence of daylight and wind, neither of the two can supply any power. In the case of ocean buoys, a potential solution is omnipresent: wave energy. Abundant, predictable, and consistent, the ocean's waves can be used to power navigation buoys. Researchers have developed sphere-based triboelectric nanogenerators that can be incorporated directly into navigational buoys to provide electricity from ocean waves.
Solar-powered microbes to feed the world?
30 Jul 2021 at 7:43am
An international research team has shown that using solar-panels to produce microbial protein -- which is rich not just in proteins but also in other nutrients -- is more sustainable, efficient and environmentally friendly than growing conventional crops. This method uses solar energy, land, nutrients, and carbon dioxide from the air.
Machine learning models to help photovoltaic systems find their place in the sun
20 Jul 2021 at 9:23am
Scientists develop algorithms that predict the output of solar cells, easing their integration into existing power grids.
Renewable energies: No wind turbine disturbing the scenery
20 Jul 2021 at 8:44am
In the Alpine foothills, in low mountain ranges, or on the seacoast, expansion of wind energy use often meets popular resistance. Researchers have now studied what this means for the energy transition.
Solar cells: Boosting photovoltaic effect in ferroelectric-paraelectric super...
20 Jul 2021 at 8:44am
The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. Researchers achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which they alternately placed on top of one another. These findings could significantly increase the efficiency of solar cells.
Renewable energy OK, but not too close to home

When it comes to transitioning from carbon-based to renewable source energy systems, Americans are on board. They're less keen, however, having these new energy infrastructures built close to their homes.
