Climate | Biden Administration to Cut Costs for Wind and Sun Energy Projects https://www.nytimes.com/2022/06/01/climate/biden-solar-wind-fees-cut.html Interior Minister Deb Haaland said the government would sharply reduce the fees it charges to companies operating on public lands. WASHINGTON – The Biden administration said Wednesday it would cut half the amount it charges companies to build wind and solar […]
How does a solar cell produce electricity Class 6? Solar cells are used because solar cells directly convert solar energy into electrical energy. Since satellites in orbit are exposed to a lot of sunlight, their systems can be recognized with the help of solar cells. How to explain how the solar cell works? A solar […]
A team of researchers led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has learned that an electrolyte additive allows stable high-voltage cycling of nickel-rich layered cathodes. Their work could lead to improvements in the energy density of lithium batteries that power electric vehicles. The findings, published on […]
China aims to double its wind and solar capacity by 2025, according to a new road map that also allows for more coal-fired power plants to bolster energy security. The world’s biggest polluter earlier estimated it needs to double wind and solar use by 2030 to deliver on its pledges under the Paris climate accord. […]
Solar energy is a popular candidate for a sustainable alternative to fossil fuels. A solar cell, or photovoltaic (PV) cell, converts sunlight directly into electricity. However, the conversion efficiency has not been enough to enable widespread applications of solar cells. A fundamental limit to the maximum efficiency of PV devices is given […]
This work is led by Prof. Qingbo Meng, Prof. Dongmei Li (Institute of Physics, the Chinese Academy of Sciences) and Dr. Hongshi Li (Nankai University). Interfacial stability and open-circuit voltage of perovskite solar cells have been mainly limited by defect states in perovskite films. Here, aiming at outstanding interfacial passivation, Prof. Meng’s […]
