Antofagasta expects 2024 copper output at low end of yearly forecast
Antofagasta produced 284,700 metric tons of copper in the first half, down 3.7% from the same period in 2023.
A group of scientists revealed Monday a record-breaking solar cell which has an efficiency of 44.7%.
This is a world record, beating the previous efficiency level of 44.4%, achieved by a group of researchers at Sharp Corporation.
The efficiency rating calculates how much incoming sunlight is converted into electricity.
After three years of research, the group – which includes the Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin – say their new solar cell structure with four solar subcells provides a “major step towards reducing further the costs of solar electricity.”
The cells are used in concentrator photovoltaics (CPV) – systems which use less solar cell material than other PV systems.
They are now working to “pave the way to the 50% efficiency roadmap.”
Soitec, a French semiconductor manufacturer, announced earlier this month another record breaker: A solar-energy module with 31.8% efficiency – “the highest of any commercial module being mass produced today,” according to the company.
