Tips: How to Use Solar Cells?

Use photons twice at a time. One of the ways solar panels lose energy is that photons can handle more energy than solar cells can. To produce electrons, solar panel’s material (typically silicon) must absorb photons with more than a certain amount of energy, called a band gap. A photon with more energy than the band gap can still produce an electron, but that electron has a lot of excess energy, which is lost with heat. Finally, all electrons leave the solar panel with approximately the same energy as the band gap of the solar cell material.

The light that guides the solar cell. This two-photon integration process has some additional benefits. The researchers created a polymer glass material embedded with nanoparticles. The particles absorb ultraviolet light in the solar spectrum, but allow the rest of the light to pass through. This produces a distinctly transparent glass structure. When ytterbium emits infrared light, it does so mainly in directions that trap the light inside the glass. The glass guides the light to the edge, where it can be absorbed by the silicon solar cell. At this stage, the end result is a solar collector with very low efficiency. Blue light produces infrared light with an efficiency of about 180%. However, only 3% of the blue light is absorbed.
