Record Power Boost for New Flexible Solar Tech

Posted by in categories: solar power, sustainability

Engineers have made bendable solar cells from ultra thin semiconductors—which for all their elasticity still boast a power-per-weight ratio on par with established thin-film solar cells.

A tool to speed development of new solar cells

Posted by in categories: computing, solar power, sustainability

A new computational simulator can help predict whether changes to materials or design will improve performance in new photovoltaic cells.

In the ongoing race to develop ever-better materials and configurations for solar cells, there are many variables that can be adjusted to try to improve performance, including material type, thickness, and geometric arrangement. Developing new solar cells has generally been a tedious process of making small changes to one of these parameters at a time. While computational simulators have made it possible to evaluate such changes without having to actually build each new variation for testing, the process remains slow.

Now, researchers at MIT and Google Brain have developed a system that makes it possible not just to evaluate one proposed design at a time, but to provide information about which changes will provide the desired improvements. This could greatly increase the rate for the discovery of new, improved configurations.

Autonomous robot for concentrated solar power installation and maintenance

Posted by in categories: robotics/AI, solar power, sustainability

Heliogen announced the roll-out of its robots to install and clean its CSP plants.

Heliogen, a California-based developer of concentrated solar power (CSP) plants, held the first technical demonstration of its ICARUS, or Installation & Cleaning Autonomous Robot & Utility Solution.

ICARUS is a system of autonomous robots designed to clean the heliostats, which are the reflective mirrors of the CSP system. Heliostats reflect sunlight into a collection tower, where the light and heat is converted to electricity and usable thermal energy. Recently, the company partnered with Bloom Energy to produce hydrogen fuel.

Researchers Show a 100% Renewable US Grid with No Blackouts Is Possible

Posted by in categories: employment, health, solar power, sustainability

And it would create 4.7 million long-term jobs.

The United States’ energy system that’s running completely on wind, water, and solar, combined with storage, would not only avoid blackouts but also lower energy requirements and consumer costs, a Stanford University study has shown. In addition, this would create millions of jobs, improve health, and free up land for various other purposes.

This is incredibly important because, for some people, a future powered by renewable energy isn’t feasible due to concerns about blackouts driven by inconsistent electricity sources. Take, for example, the grid blackouts caused by extreme weather events in California in August 2020 and Texas in February 2021.

Giant solar power plants of the Sahara

Posted by in categories: climatology, media & arts, solar power, sustainability

Tens of thousands of years ago, on the territory of the uninhabited Sahara Desert, gardens flourished, rivers flowed, ancient people cultivated fertile lands. However, we know how it all ended — today in this place is a desert scorched by the blazing sun with an area 38 times the size of Great Britain. However, humanity has a chance to return life to these lands again, and as a bonus to receive free electricity for all inhabitants of the planet.
The installation of wind and solar farms could radically change the climate in this region: more rainfall, which will lead to a revival of vegetation and a drop in temperature. At least that’s what Yang Li, the study’s author and senior researcher at the University of Illinois, says. No mystery! Wind turbines facilitate the diffusion of hot and cool air. This, in turn, will raise the average rainfall by 50%, and solar panels absorb most of the solar energy, preventing it from overheating the earth.
All this will be effective only with the global development of a lifeless desert. The process has already begun. But they tried repeatedly to tame the cruel and hot sun of the Sahara.

Airobotics, Solar Drone to develop new drone for solar panels cleaning

Posted by in categories: drones, mapping, robotics/AI, solar power, sustainability

Israeli drone manufacturer Airobotics has collaborated with Israeli solar farm services company Solar Drone to develop and supply to Solar Drone a unique solar panel cleaning drone system. The fully automated system will include a drone docking station for automatic battery replacement and cleaning fluid replenishment, enabling the system to operate continuously.

While solar power and solar panels are essentially maintenance-free systems, but solar panels do require cleaning from time to time to enable proper function. Dirt, dust, mud, and bird dropping greatly reduce solar panel efficiency, impacting power output. Frequent cleaning is expensive and time-consuming, especially when panels are remote, difficult to access, or difficult to clean.

Pythagoras’ Revenge: Humans Didn’t Invent Mathematics, It’s What the Physical World Is Made Of

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

Graphene consists of a planar structure, with carbon atoms connected in a hexagonal shape that resembles a beehive. When graphene is reduced to several nanometers (nm) in size, it becomes a graphene quantum dot that exhibits fluorescent and semiconductor properties. Graphene quantum dots can be used in various applications as a novel material, including display screens, solar cells, secondary batteries, bioimaging, lighting, photocatalysis, and sensors. Interest in graphene quantum dots is growing, because recent research has demonstrated that controlling the proportion of heteroatoms (such as nitrogen, sulfur, and phosphorous) within the carbon structures of certain materials enhances their optical, electrical, and catalytic properties.
