Solar Groves

If one solar cluster is a “tree” then it seems apt that placing several solar trees in one particular area is becoming known as a solar “grove.” In case you aren’t familiar, a solar tree is a little like a modern day lamp post, only with Solar Panels atop to light the way. Envision Solar [...]

Like plants, solar cells turn light into energy. Plants do this inside vegetable matter, while solar cells do it in a semiconductor crystal doped with extra atoms. Current solar cells cannot convert all the incoming light into usable energy because some of the light can escape back out of the cell into the air. Additionally, sunlight comes in a variety of colors and the cell might be more efficient at converting bluish light while being less efficient at converting reddish light.

 

The nanoparticle approach seeks to remedy these problems. The key to this new research is the creation of a tiny electrical disturbance called a “surface plasmon.” When light strikes a piece of metal it can set up waves in the surface of the metal. These waves of electrons then move about like ripples on the surface of a pond. If the metal is in the form of a tiny particle, the incoming light can make the particle vibrate, thus effectively scattering the light. If, furthermore, the light is at certain “resonant” colors, the scattering process is particularly strong. Read the rest of this entry »

Solar Cells

A “solar cell” is a device which changes sunlight into electricity. More technically, a solar cell is also referred to as a “photovoltaic cell.”
The term “photo” derives from the Greek word for “light,” and the term “voltaic” comes from the word “volt” which means “electrical force.” A “cell” is a small receptacle or container containing [...]
