A team of researchers from the University of Toronto has created a triple-junction perovskite solar cell with record efficiency by overcoming a key limitation of previous designs.

The prototype represents a significant advance in the development of low-cost alternatives to silicon-based solar cells, which are the current industry standard.

“In addition to lower manufacturing cost, perovskites offer us the ability to stack multiple layers of light-absorbing materials on top of each other, and even on top of traditional silicon cells,” says Professor Ted Sargent, who recently joined the departme...

Earth’s water could have originated from interactions between the hydrogen-rich atmospheres and magma oceans of the planetary embryos that comprised Earth’s formative years, according to new work from Carnegie Science’s Anat Shahar and UCLA’s Edward Young and Hilke Schlichting. Their findings, which could explain the origins of Earth’s signature features, are published in Nature.

For decades, what researchers...

After upgrading the radio telescope array at Westerbork, The Netherlands, astronomers have found five new fast radio bursts. The telescope images, much sharper than previously possible, revealed that multiple bursts had pierced our neighboring Triangulum galaxy. This allowed the astronomers to determine the maximum number of otherwise invisible atoms in this galaxy for the first time...
