In an article published in the Journal of Materials Chemistry C, Brazilian researchers describe a strategy to enhance the efficiency and stability of solar cells made of perovskite, a semiconductor material produced in the laboratory. The results of the project could be highly positive for the future of the solar power sector.
Copper smelting is a major source of copper production, generating significant amounts of slag. In 2022, China produced over 11,000 kilotons of refined copper, leading to 2.2 to 3 tons of slag per ton of copper produced. This slag contains valuable metals like copper (0.5%–6%), lead (0.2%–0.6%), and zinc (1%–5.5%), which are often not recovered, resulting in resource waste and environmental hazards from leaked toxic ions.
To become carbon neutral by 2060, as mandated by President Xi Jinping, China will have to build eight to 10 times more wind and solar power installations than currently exist in the country. Reaching carbon neutrality will also require major construction of transmission lines.
Power cuts can be caused by heavy snow and icing, as well as lightning strikes and strong winds bringing down power lines. Together with more extreme weather events, Norway is also facing a major power supply deficit. So what can we do to avoid a total electricity crisis?
A new generation of commercial electric vehicles is emerging to reduce air pollution and congestion in urban areas.
Uppsala University is the new world record holder for electrical energy generation from copper indium gallium selenide (CIGS) solar cells. The new world record is 23.64% efficiency. The measurement was made by an independent institute, and the results are published in Nature Energy.
Developers of a huge wind farm proposed for construction near Anchorage say it could help provide a much-needed boost to the area’s energy needs, and will be most productive when it’s most needed, when temperatures drop and demand for energy soars.
