New Quantum Dot Technology Improves Solar Cell Efficiency

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

A research team has developed a novel “pulse-shaped” light method to enhance the electrical conductivity of PbS quantum dot solar cells. This new technique, which replaces the lengthy traditional heat treatment process, generates substantial energy at regular intervals, significantly improving efficiency and addressing defects caused by light, heat, and moisture exposure. PbS quantum dots, known for their wide absorption range and low processing costs, are now more viable for commercial use. This advancement is expected to facilitate the broader application of quantum dot technology in optoelectronic devices. Credit: SciTechDaily.com.

A research team headed by Professor Jongmin Choi from the Department of Energy Science and Engineering at Daegu Gyeongbuk Institute of Science and Technology has successfully developed a “PbS quantum dot” capable of quickly improving the electrical conductivity of solar cells. This collaborative effort involved Professor Changyong Lim of the Department of Energy Chemical Engineering at Kyungpook National University, led by President Wonhwa Hong, and Professor Jongchul Lim from the Department of Energy Engineering at Chungnam National University, under the leadership of President Jeongkyoum Kim.

The team identified a method to enhance electrical conductivity through the use of “pulse-shaped” light, which generates substantial energy in a concentrated manner at regular intervals. This method could replace the heat treatment process, which requires a significant amount of time to achieve the same result. This approach is expected to facilitate the production and commercialization of PbS quantum dot solar cells in the future.

Increasing use of renewable energy in US yields billions of dollars of benefits

They found emissions of SO2 and NOx – both linked to increased asthma risk and a variety of other health issues – decreased by a total of 1m metric tons over that three-year period.

To determine the impact of that reduction on public health, the authors “used air quality models to track the population exposed to pollution from power plants”, Millstein said. They also employed epidemiological research to examine the effects of those emissions, and quantified the benefits by using an Environmental Protection Agency dollar value establishing the value of reducing the risk of early death across the population, he said.

All told, the emission reductions from SO2 and NOx provided $249bn of climate and health benefits to the US, the authors found – a figure Millstein said he found was “noteworthy”

Ford teases new F-150 Lightning-based EV SuperTruck ahead of Pikes Peak [Video]

Posted by in categories: climatology, sustainability

Ford Performance is at it again. The high-performance unit is teasing its new Ford F-150 Lightning-based EV SuperTruck ahead of its official debut. To showcase its abilities, Ford’s new electric SuperTruck will compete in the upcoming Pikes Peak International Hill Climb.

Based on its best-selling electric pickup, Ford’s Performance team tweaked the Lightning-based EV SuperTruck to boost power and aerodynamics.

Ford says running test electric vehicles at Pikes Peak enables it to “push the boundaries of EV powertrains in the most extreme conditions.” The team then relays what it learns to improve Ford’s production vehicles.

Top US coal producer Wyoming just approved a $1.2B solar farm

Posted by in categories: solar power, sustainability

Wyoming just approved its largest solar farm – 771 megawatts (MW) of utility-scale solar plus battery storage.

Developer Enbridge has been issued a siting permit by the Industrial Siting Council to construct and operate Cowboy Solar I & II on private land leases in Laramie County, in the state’s southeast corner. Next steps will be to obtain county, environmental, and municipal permits.

Cowboy Solar I will include 400 MW of solar power and 136 MW of battery storage, while Cowboy Solar II will have 371 MW of solar power and 133 MW of battery storage.

Tesla to launch new Performance mode for Model 3 and Y

Posted by in categories: sustainability, transportation

Tesla appears to be gearing up to launch a new Performance mode for the Model 3 and Model Y, as spotted in code from recent firmware updates.

On Sunday, Tesla code sleuth green the only posted about a “soft performance limit” option for the Model 3 and Y discovered in recent firmware, which the account says are listed as 110kW and 160kW, respectively. The discovery seems to suggest that Tesla is looking to launch a paid upgrade for the software-locked mode, allowing owners to upgrade to access full battery range.

Hm, interesting, recent firmwares bring “soft performance limit” option to Model3 and ModelY, listed as 110kW and 160kW respectively.
