Space mission tests NREL perovskite solar cells

On a clear night, Kaitlyn VanSant will be able to watch her work whiz by. Knowing the success of her project, however, will have to wait until her tiny, temporary addition to the International Space Station returns to Earth.

Germanium-lead perovskite LEDs: A new way to reduce toxicity

Metal-halide perovskites are a new class of semiconductor materials for LED display and solar-energy harvesting. However, the best-performing devices are often made from lead (Pb)-based perovskites, whose toxicity may cause ...

Perovskites under pressure: Hot electrons cool faster

In solar cells, about two third of the energy of sunlight is lost. Half of this loss is due to a process called 'hot carrier cooling' where high energy photons lose their excess energy in the form of heat before being converted ...

Carbon dots from human hair boost solar cells

QUT researchers have used carbon dots, created from human hair waste sourced from a Brisbane barbershop, to create a kind of "armor" to improve the performance of cutting-edge solar technology.

Mystery of amorphous perovskite solved

AMOLF researchers Erik Garnett, Susan Rigter, and colleagues are the first to have irrefutably demonstrated that amorphous perovskite exists. The material can significantly increase the efficiency of solar cells produced ...

A new modifier increases the efficiency of perovskite solar cells

The research team of NUST MISIS has presented an improved structure of perovskite solar cells. Scientists have modified perovskite-based solar cells using MXenes—thin two-dimensional titanium carbides with high electrical ...

New way to power up nanomaterials for electronic applications

UCLA materials scientists and colleagues have discovered that perovskites, a class of promising materials that could be used for low-cost, high-performance solar cells and LEDs, have a previously unutilized molecular component ...
