Sentences with phrase «photons at infrared wavelengths»

TPV operates on the same principle as solar cells in wide use today, but converts photons at infrared wavelengths rather than those in the visible spectrum.

Not exact matches

The actual wavelengths / photons / particles of visible light are really tiny — all high energy signifies here is that the waves are closer together and smaller in height, they are so because travelling at the same speed as longer waves they have to be considerably smaller, and end up being microscopic like near infrared and visible is even smaller, thermal infrared can be the size of a finger nail.
