Quantum Dot Light Enhancement Substrate

A cost-competitive solution for increasing the light extraction efficiency of organic light-emitting diodes (OLEDs) with efficient and stable color rendering index (CRI) for solid-state lighting (SSL) was developed and demonstrated. Solution-processable quantum dot (QD) films were integrated into OLED indium tin oxide (ITO)-glass substrates to generate tunable white emission from blue-emitting OLED devices.

Looking at Atmospheric Stability to Predict Wind Power

Power generated by a wind turbine largely depends on wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes, such as turbulence, to the wind profile, a turbine will produce different amounts of power. Two researchers say that this variable power can be predicted by looking at atmospheric stability.

Charged Quantum Dots Increase Solar Cell Efficiency

With military colleagues, a trio of University at Buffalo engineers have shown that embedding charged quantum dots into photovoltaic cells can improve electrical output by enabling the cells to harvest infrared light, and by increasing the lifetime of photoelectrons.

Superconducting Current Limiter

A new superconducting current limiter based on YBCO strip conductors has been installed at a power plant. At the Boxberg power plant of the Swedish company Vattenfall, the current limiter protects the grid for own consumption that is designed for 12,000 volts and 800 amperes against damage due to short circuits and voltage peaks.

Sunflower-Inspired Pattern Increases Concentrated Solar Efficiency

There are only a handful of concentrated solar power (CSP) plants in the world. The technology could potentially generate enough renewable energy to power the entire U.S., provided that land and sunlight are in ample supply. Researchers have now come up with a design that reduces the amount of land required to build a CSP plant, while increasing the amount of sunlight its mirrors collect.
