The practical applications could improve the efficiency of quantum computers, where light is often used to transfer information.

He says that the FCC paper is only talking about the amount of light that's transmitted to the device, not the efficiency of the device itself.
In the previous approaches so far, the systems have had complex structures such as organic complexes or plural photo-electrodes, which makes it difficult to improve their efficiency in response to the light.
The rising use of aluminum in passenger cars and light trucks comes because of rising fuel-efficiency standards in the U.S., he said.
They absorb the light and convert light to heat with incredible efficiency.
At the same time, efficiency programs are pushing more efficient light bulbs, air conditioners and other devices into homes.
Sandwiching the solar cells inside the device would block some light out and knock down power conversion efficiency even further, Filler cautioned.
All engineering mumbo-jumbo aside, the resulting nanocone-tipped cells converted light-to-power with efficiency of 3.2% compared to 1.8% efficiency of conventional planar structure of the same materials.

There's even a "white tag" market: When I install a more efficient light bulb, I can sell that efficiency gain to the fossil fuel power plant, just as if it's a green tag.
The growth sector for the last quarter century has been light trucks, a category in which fuel efficiency has deteriorated over time.
And over the next five years, we expect fuel efficiency standards in cars and light trucks to reach an average of 35.5 miles per gallon.
The important measure of success is the internal quantum efficiency, which shows just how good an LED is at making light.
C. to announce the next round of a coordinated national program to improve fuel efficiency for cars and light-duty trucks for model years 2017 to 2025.
Making small, light, efficient, cheap cars is hard, and harder as the standard for lightness, smallness, efficiency, and economy is raised.

Under the proposal, model year 2017-2025 cars and light-duty trucks are expected to achieve increases in fuel efficiency equivalent to 54.5 miles per gallon by 2025.
