Perovskite-CIGS tandem solar cells have technical potential to achieve 26.69% efficiency
A Dutch and U.S. research team performed optical and electrical simulations to understand loss mechanisms in two terminal (2T) tandem cells based on perovskite and commercially available copper-indium-gallium-selenide (CIGS) cells, and subsequently established a roadmap to increase efficiency via four key modifications.

First Solar commissions 1.3 million square-foot R&D facility
The Jim Nolan Center for Solar Innovation in Lake Township, Ohio includes a high-tech pilot manufacturing line allowing for the production of full-sized prototypes of thin film and tandem PV modules.
Peak Energy secures $55 million Series A funding to manufacture sodium-ion batteries
The company plans to deliver its first systems in 2025 and open a full-scale production facility in 2027.
Elastocalorics could replace heat pumps, air conditioning systems
Elastocalorics have the potential to replace current air conditioning and heating systems, offering significant energy savings when paired with technologies such as photovoltaics.
All-perovskite tandem solar cell based on tin-lead perovskite achieves 27.8% efficiency
Scientists in the United States have fabricated an all-perovskite tandem solar cell that reportedly shows reduced interfacial energy loss in the cell’s top device. It was built with a hole transport layer based on a compound known as P3CT that was doped with lead iodide.
Residential PV power forecasting method based uniquely on direct radiation
Researchers in Spain have created a novel PV forecasting method that uses only direct radiation as a parameter. They found it to be “comparable, if not superior” to four established forecasting techniques. The method could help homeowners with PV systems decide when to use electricity-intensive appliances and cleaning systems.
