Etching a Simple Pattern on Solar Panels Boosts Light Absorption

Posted by in categories: solar power, sustainability

A simple way to improve efficiency…


Solar panels offer huge potential to move more people away from electricity generated from burning coal, and a new innovation devised by scientists stands to more than double the amount of light captured by conventional solar cells.

In a new study, a team of scientists from the UK, Portugal, and Brazil discovered that etching a shallow pattern of grating lines in a checkerboard design on solar cells can enhance the current generated by crystalline silicon (c-Si) by as much as 125 percent.

Turning Diamond Into Metal – For Improved Solar Cells, LEDs, and Power Electronics

Posted by in categories: quantum physics, solar power, sustainability

Normally an insulator, diamond becomes a metallic conductor when subjected to large strain in a new theoretical model.

Long known as the hardest of all natural materials, diamonds are also exceptional thermal conductors and electrical insulators. Now, researchers have discovered a way to tweak tiny needles of diamond in a controlled way to transform their electronic properties, dialing them from insulating, through semiconducting, all the way to highly conductive, or metallic. This can be induced dynamically and reversed at will, with no degradation of the diamond material.

The research, though still at an early proof-of-concept stage, may open up a wide array of potential applications, including new kinds of broadband solar cells, highly efficient LEDs and power electronics, and new optical devices or quantum sensors, the researchers say.

Researchers first to develop an organic battery

Posted by in categories: solar power, sustainability, transportation

Are organic batteries coming?


Researchers at the Laboratory of Organic Electronics, Linköping University, have for the first time demonstrated an organic battery. It is of a type known as a ‘redox flow battery,” with a large capacity that can be used to store energy from wind turbines and solar cells, and as a power bank for cars.

Redox flow batteries are stationary batteries in which the is located in the electrolyte, outside of the cell itself, as in a fuel cell. They are often marketed with the prefix ‘eco,” since they open the possibility of storing from, for example, the sun and wind. Further, it appears to be possible to recharge them an unlimited number of times. However, redox flow batteries often contain vanadium, a scarce and expensive metal. The electrolyte in which energy is stored in a redox flow battery can be water-based, which makes the battery safe to use, but results in a lower energy density.

Alphabet’s New Moonshot Is to Transform How We Grow Food

Posted by in categories: food, genetics, solar power, sustainability

Mineral’s plant buggy looks like a platform on wheels, topped with solar panels and stuffed with cameras, sensors, and software.


But maybe there’s a better way—and Mineral wants to find it.

Like many things nowadays, the key to building something better is data. Genetic data, weather pattern data, soil composition and erosion data, satellite data… The list goes on. As part of the massive data-gathering that will need to be done, X introduced what it’s calling a “plant buggy” (if the term makes you picture a sort of baby stroller for plants, you’re not alone…).

Exploring chemical space: Can AI take us where no human has gone before?

Posted by in categories: biotech/medical, chemistry, robotics/AI, solar power

Chemical space contains every possible chemical compound. It includes every drug and material we know and every one we’ll find in the future. It’s practically infinite and can be frustratingly complex. That’s why some chemists are turning to artificial intelligence: AI can explore chemical space faster than humans, and it might be able to find molecules that would elude even expert scientists. But as researchers work to build and refine these AI tools, many questions still remain about how AI can best help search chemical space and when AI will be able to assist the wider chemistry community.

Outer space isn’t the only frontier curious humans are investigating. Chemical space is the conceptual territory inhabited by all possible compounds. It’s where scientists have found every known medicine and material, and it’s where we’ll find the next treatment for cancer and the next light-absorbing substance for solar cells.

But searching chemical space is far from trivial. For one thing, it might as well be infinite. An upper estimate says it contains 10180 compounds, more than twice the magnitude of the number of atoms in the universe. To put that figure in context, the CAS database—one of the world’s largest—currently contains about 108 known organic and inorganic substances, and scientists have synthesized only a fraction of those in the lab. (CAS is a division of the American Chemical Society, which publishes C&EN.) So we’ve barely seen past our own front doorstep into chemical space.

Solar meets 100 per cent of South Australia demand for first time

Posted by in categories: solar power, sustainability

The combination of rooftop and utility scale solar met 100 per cent of demand in South Australia for the first time on Sunday, reaching a milestone that will surely be repeated many times over – and for longer periods – in the future.

The milestone was reached at 12.05pm grid time (Australian eastern standard time), with rooftop solar providing 992MW, or 76.3 per cent of state demand, and utility scale solar providing a further 315MW – meaning all three of the state’s big solar farms, Bungala 1m Bungala 2 and Tailem Bend were operating at full capacity.
