Terabase Energy has successfully completed its first commercial solar installation using Terafab, its automatic solar-installing robot.

The Terafab robot – aka the “construction automation platform” – installed 17 megawatts (MW) of the 225 MW White Wing Ranch project in Yuma County, Arizona, on which solar tech company Terabase Energy is working alongside developer Leeward Renewable Energy (LRE) and contractor RES.

The Terafab robot completely eliminates the manual lifting of heavy steel tubes and solar panels – an industry first. Terabase Energy says that its robot achieved labor productivity improvements of 25% compared with manual installation, and the setup improves working conditions for solar technicians, as they’re housed in shaded and cooled conditions. The robot’s precision also enables the 100% return of solar panel packaging for reuse by the manufacturer.

Immigration and living on Mars have long been depicted in science fiction works. But before dream turns into reality, there is a hurdle man has to overcome — the lack of essential chemicals such as oxygen for long-term survival on the planet. However, hope looms up thanks to recent discovery of water activity on Mars. Scientists are now exploring the possibility of decomposing water to produce oxygen through electrochemical water oxidation driven by solar power with the help of oxygen evolution reaction (OER) catalysts. The challenge is to find a way to synthesize these catalysts in situ using materials on Mars, instead of transporting them from the Earth, which is of high cost.

To tackle this problem, a team led by Prof. LUO Yi, Prof. JIANG Jun, and Prof. SHANG Weiwei from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), recently made it possible to synthesize and optimize OER catalysts automatically from Martian meteorites with their robotic artificial intelligence (AI)-chemist.

A new report by Wood Mackenzie reveals that China will control over 80 percent of the world’s production of polysilicon, wafers, cells, and modules — the critical components of solar panels — from 2023 to 2026.

“This is significant because it creates the opportunity for greater renewable energy storage.”

Through the use of solar collectors, concentrated solar thermal technology (CST) harnesses solar energy to produce heat or electricity. The process is simple although difficult to execute successfully: large mirrors or lenses focus sunlight onto a narrow region known as the receiver.

These mirrors are what are known as solar collectors and they come in a variety of formats each with a distinct design and focusing technique, such as dish systems, solar power towers, and parabolic troughs.

Researchers at EPFL and Northwestern University have unveiled a groundbreaking design for perovskite solar cells, creating one of the most stable PSCs with a power-conversion efficiency above 25%, paving the way for future commercialization.

Perovskite (PSCs) stand at the forefront of solar energy innovation, and have drawn a lot of attention for their power-conversion efficiency and cost-effective manufacturing. But the way to commercialization of PSCs still has a hurdle to overcome: achieving both and long-term , especially in challenging environmental conditions.

The solution lies in the interplay between the layers of PSCs, which has proven to be a double-edged sword. The layers can enhance the cells’ performance but also cause them to degrade too quickly for regular use in everyday life.

Artificial photosynthesis, the next-generation technology, has now come this far! It is a technology that mimics plant photosynthesis to produce energy from resources found on earth such as sunlight and carbon dioxide. This is a promising new solution to energy and environmental problems as it can efficiently produce hydrogen and other substances. Japan was one of the first countries to recognize this technology and had launched a national project that involved the collaboration among industry, academia, and government. In 2021, they successfully produced large amounts of hydrogen, taking the world by surprise. Also in this episode, take a look at a system that can power homes using carbon dioxide. Find out the latest in artificial photosynthesis with reporter Michelle YAMAMOTO.

Researchers at Tokyo Tech have demonstrated that in-cell engineering is an effective method for creating functional protein crystals with promising catalytic properties. By harnessing genetically altered bacteria as a green synthesis platform, the researchers produced hybrid solid catalysts for artificial photosynthesis.

Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.

Caltech researchers have discovered Hubbard excitons, which are excitons bound magnetically, offering new avenues for exciton-based technological applications.

In art, the negative space in a painting can be just as important as the painting itself. Something similar is true in insulating materials, where the empty spaces left behind by missing electrons play a crucial role in determining the material’s properties. When a negatively charged electron is excited by light, it leaves behind a positive hole. Because the hole and the electron are oppositely charged, they are attracted to each other and form a bond. The resulting pair, which is short-lived, is known as an exciton [pronounced exit-tawn].

Excitons are integral to many technologies, such as solar panels, photodetectors, and sensors. They are also a key part of light-emitting diodes found in televisions and digital display screens. In most cases, the exciton pairs are bound by electrical, or electrostatic, forces, also known as Coulomb interactions.
