Organic-inorganic halide perovskite materials have excellent optical capture capacity and carrier conductivity. Perovskite solar cells, with amazing power conversion efficiency, show great application ...

2,5-furandicarboxylic acid (FDCA), which is produced by oxidation of 5-hydroxymethylfurfural (HMF), is the crucial precursor for the production of polyethylene 2,5-furandicarboxylate to replace ...

Scientists led by Switzerland’s École Polytechnique Fedérale de Lausanne (EPFL) demonstrated a simple approach to designing the interface between two layers in a perovskite solar cell, which was shown ...

Researchers have devised and tested a new, highly sensitive method of detecting and counting defects in transistors -- a matter of urgent concern to the semiconductor industry as it develops new ...

A single pulse of ultrasound fired into the polymer encapsulant of a TO-247 device travels through the polymer at a speed around 3,000 m/s. Its mission is to characterize any internal material ...

Defects in transistors, such as unwanted impurities and broken chemical bonds in the various layers of the semiconductor, can limit their performance and reliability. These defects are becoming harder ...

The formation of lithium dendrites is still a mystery, but materials engineers study the conditions that enable dendrites and how to stop them. Historically, as in decades ago, rechargeable lithium ...
