Engineers have synthesized a tiny structure with high surface area and discovered how its unique architecture drives ions across interfaces to transport energy or information...

Relatively inexpensive compound could perform safely and effectively in solar cells. A team of engineers, material scientists, and physicists demonstrated how a new material — a lead-free chalcogenide perovskite — that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered.

A widespread transition to solar energy will depend heavily on reliable, safe, and affordable technology like batteries for energy storage and solar cells for energy conversion. At Rensselaer Polytechnic Institute, researchers are focused heavily on both parts of that equation.

In research published today in Advanced Functional Materials, a team of e...

Silver-based electrode films could be used for flexible touch displays, televisions and solar cells. Researchers have demonstrated large-scale fabrication of a new type of transparent conductive electrode film based on nanopatterned silver. Smartphone touch screens and flat panel televisions use transparent electrodes to detect touch and to quickly switch the color of each pixel...

Perylene bisimides are a heavily investigated and sought after class of organic pigments, since they show interesting dye properties. While these compounds are red pigments in the solid state, when dissolved, they generate bright yellowish-green solutions under UV irradiation. Aside their optical appeal; organic molecules that appear colored in daylight often also show intriguing electronic properties. Thus, organic dyes are promising lightweight materials for application as e.g. organic semiconductors, but also in for instance LCD displays or solar cells.
