Novel Perovskite Solar Cell Could Rival Silicon [Video]

Novel Perovskite Solar Cell Could Rival Silicon [Video]

A new design for solar cells that uses inexpensive, commonly available materials could rival and even outperform conventional cells made of silicon. Scientists have used tin and other abundant elements to create novel forms of perovskite—a photovoltaic crystalline material that’s thinner, more flexible, and easier to manufacture than silicon crystals. “Perovskite semiconductors have shown great promise

This Electronic Material Heals After Being Cut in Two [Video]

A new electronic material can heal all its functions automatically—even after breaking multiple times. This material could improve the durability of wearable electronics. “Wearable and bendable electronics are subject to mechanical deformation over time, which could destroy or break them,” says Qing Wang, professor of materials science and engineering at Penn State. “We wanted to

Vibrating Grains May Lead to New Designer Coatings

On the microscale, granular materials interact in remarkably complex ways. That complexity makes them one of the least understood forms of matter. Now scientists want to figure out how to take advantage of those interactions to design impact-absorbing materials. For example, these new materials might minimize vibrations in vehicles, better protect military convoys, or potentially

How Gecko Feet Inspired New Dust Cleaning Polymer

Micrometric and sub-micrometric contaminant particles—what most of us call “dust”—are everywhere. Dust makes it tough to keep the house clean, but it also causes problems for art conservators, the electronics industry, and aerospace engineers. Now, scientists want to use static cling and the science behind gecko feet to develop a tool that could help fight dust.
