Perovskites, a family of materials defined by a particular kind of molecular structure as illustrated here, have great potential for new kinds of solar cells. A new study from MIT shows how these materials could gain a foothold in the solar marketplace.

Researchers develop a roadmap for growth of new solar cells

Starting with higher-value niche markets and then expanding could help perovskite-based solar panels become competitive with silicon.

With a new technique, MIT researchers can peel and stack thin films of metal oxides — chemical compounds that can be designed to have unique magnetic and electronic properties. The films can be mixed and matched to create multi-functional, flexible electronic devices, such as solar-powered skins and electronic fabrics.

Engineers mix and match materials to make new stretchy electronics

Next-generation devices made with new “peel and stack” method may include electronic chips worn on the skin.

A preserved heart muscle (1) is removed and replaced with a soft synthetic matrix (2). The two structures (inner cardiac tissue and synthetic matrix) (3) are bonded using a newly developed adhesive, TissueSil (4). The resulting piece is the biohybrid heart containing the preserved intracardiac structures and synthetic heart muscle (5).

Engineers design bionic “heart” for testing prosthetic valves, other cardiac devices

Device made of heart tissue and a robotic pumping system beats like the real thing.

Currently, 90 percent of the world’s solar panels are made from crystalline silicon, and the industry continues to grow at a rate of about 30 percent per year.

For cheaper solar cells, thinner really is better

Solar panel costs have dropped lately, but slimming down silicon wafers could lead to even lower costs and faster industry expansion.

This sensor can measure blood glucose levels noninvasively by shining near-infrared light through the skin and measuring the chemical composition of the tissue below.

Researchers hope to make needle pricks for diabetics a thing of the past

Study suggests noninvasive spectroscopy could be used to monitor blood glucose levels.

A smart window developed by Professor Nicholas Fang includes thermochromic material that turns frosty when exposed to temperatures of 32 C or higher, such as when a researcher touches the window with her hand.

Preventing energy loss in windows

Mechanical engineers are developing technologies that could prevent heat from entering or escaping windows, potentially preventing a massive loss of energy.

A new ultrasound technique uses lasers to produce images beneath the skin, without making contact with the skin as conventional ultrasound probes do. The new laser ultrasound technique was used to produce an image (left) of a human forearm (above), which was also imaged using conventional ultrasound (right).

Researchers produce first laser ultrasound images of humans

Technique may help remotely image and assess health of infants, burn victims, and accident survivors in hard-to-reach places.
