Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries and are contributing ...

Inverted perovskite solar cells offer strong potential for scalable, low-cost solar power, but a hidden interface inside the device has limited their performance and durability. Researchers have now ...

Perovskite single crystals have emerged as a premier platform for next-generation optoelectronic devices, combining exceptional charge transport properties with low defect densities and high ...

A new kind of ‘camera’ is poking at the invisible world of the human body – and it’s made from the same weird crystals that once shook up solar energy. Researchers at Northwestern University and ...

This big step was possible because of two important discoveries: Albert Einstein explained how light can produce electricity—called the photoelectric effect. He won the Nobel Prize for this work. Jan ...
