There is a cheaper way to make solar panels, also called photovoltaics (PVs), using crystal structures called perovskites. However, perovskite crystals contain toxic elements like lead ...

Perovskite solar cell research has made remarkable progress over the past 15 years. Back in 2009, photovoltaic devices made from cheap and abundant perovskite materials converted sunlight into ...

X-ray crystallography is a technique used to reveal how the atoms of crystalline solids are arranged, relying upon the diffraction of X-ray radiation by the periodic atomic structure. Its ...
