Brookhaven’s Lab Finds Quantum Dots Enhance Light to Current Conversion in Semiconductors

Harnessing the power of the sun and creating light-harvesting or light-sensing devices requires a material that both absorbs light efficiently and converts the energy to highly mobile electrical current. Finding the ideal mix of properties in a single material is a challenge, so scientists have been experimenting with ways to combine different materials to create "hybrids" with enhanced features.

European Scientists Make Breakthrough in OLED Technology to Achieve Cheaper Lighting and Flexible Solar Cells

In more than three years of work European scientists finally made future lighting technology ready to market. They developed flexible lighting foils that can be produced roll-to-roll – much like newspapers are printed. These devices pave the path towards cheaper solar cells and LED lighting panels. The project named TREASORES was led by Empa scientist Frank Nüesch and combined knowhow from nine companies and six research institutes in five European countries.

DOE's Proposed Light Bulb Energy Efficiency Standards to Save Consumers an Annual US$12.5 Billion

New light bulb energy efficiency standards proposed by the U. S. Department of Energy (DOE) completed the gradual phase-out of inefficient everyday incandescent bulbs required under a 2007 law passed by a bipartisan Congress with industry support. And once all of America's approximately 4 billion lighting sockets contain energy-saving bulbs that meet the standards, U.S. consumers and businesses will save about $12.5 billion every year--and gain cleaner air and a healthier environment.

Smart Lighting Designs in LCD Backlight Proximity Sensors

One of the benefits of automating control systems within buildings is the ability to customize services and personalize a user’s environment; the human machine interface (HMI) is the gateway to such controls. The addition of proximity sensing is an underutilized improvement to many interfaces in an automated building ecosystem, including thermostats, security-system keypads, monitors and elevator call buttons. Proximity sensors can improve the user experience, decrease power consumption, and increase the life of the liquid crystal display (LCD) and backlight.
