Sentences with phrase «converting photons of light»

Plants carry out photosynthesis by converting photons of light striking their chromophores into another form of energy known as an exciton.

Not exact matches

Nanocrystals selectively infused, or «doped», with rare - earth ions have attracted the attention of researchers, because of their low toxicity and ability to convert low - energy laser light into violet - colored luminescence emissions — a process known as photon upconversion.

By first converting the sunlight to heat and then back into light, the device fine - tunes the energy of photons absorbed by the photovoltaic cell, maximizing the electricity - generating potential.

It eliminates the need for information traveling along the Internet to be converted from photons (light pulses) to electrons and back - often hundreds of times for a single message traveling coast to coast.

In the first step, incoming photons — packets of light — are converted to pairs of negatively - charged electrons and corresponding positively - charged «holes» that then separate from each other.

That's because the gas can be used to make several of the layers in a silicon photovoltaic — from the top of the cell where it is used to deposit a layer of silicon nitride that ensures that all sunlight is absorbed, to the bottom where it can be used to deposit another layer that helps reflect back any missed photons of sunlight, boosting the efficiency of the cell at converting light into electricity.

The easier that electrons can move around in a solar cell material, the more efficient that material will be at converting photons, particles of light, into electricity.

The detector includes a charge - coupled device (CCD), which gathers photons of light and converts them into picture elements, or pixels.

Two key properties of fluorophores that determine brightness are the extent to which the excitation light is absorbed and the efficiency by which absorbed photons are converted into emitted photons.
