Photosensitive perovskites change shape when exposed to light

A crystalline material that changes shape in response to light could form the heart of novel light-activated devices. Perovskite crystals have received a lot of attention for their efficiency at converting sunlight into electricity, ...

Making sense of failure in light-harvesting semiconductors

While metal oxide semiconductors have been widely considered to exhibit outstanding durability, performance degradation in these solar energy harvesting components is frequently observed. Understanding the degradation is ...

Catching more of the sun

Combining quantum dots and organic molecules can enable solar cells to capture more of the sun's light.

Watching electrons cool in 30 quadrillionths of a second

Two University of California, Riverside assistant professors of physics are among a team of researchers that have developed a new way of seeing electrons cool off in an extremely short time period.

Wrapping buildings in a layer of insulating liquid

Large-area fluidic windows use a fluid contained in microchannels to harvest ambient heat and solar energy and manage heat exchange, thereby boosting energy efficiency.

Harvesting energy from electromagnetic waves

For our modern, technologically-advanced society, in which technology has become the solution to a myriad of challenges, energy is critical not only for growth but also, more importantly, survival. The sun is an abundant ...
