New material can enhance energy, computer, lighting technologies

November 15, 2011

Crystal erbium compound offers superior optical properties

…

Erbium materials can also be used to increase the energy-conversion efficiency of silicon solar cells.

Silicon does not absorb solar radiation with wavelengths longer than 1.1 microns, which results in waste of energy – making solar cells less efficient.

Erbium materials can remedy the situation by converting two or more photons carrying small amounts of energy into one photon that is carrying a larger amount of energy. The single, more powerful photon can then be absorbed by silicon, thus increasing the efficiency of solar cells.

Erbium materials also help absorb ultraviolet light from the sun and convert it into photons carrying small amounts of energy, which can then be more efficiently converted into electricity by silicon cells. This color-conversion function of turning ultraviolet light into other visible colors of light is also important in generating white light for solid-state lighting devices.

(Naturally, erbium is a “rare earth.”)

1. The rare earth part is

about resource availability and cost. We know how that goes.

I am waiting patiently for the discovery of: nonevictium, hungerendal, wageupolite, placetoliv crystals, equaldistributium, elitoff and other wonders like that.
