In the age of  rising energy costs, the idea of the free and virtually limit less energy source seems too good to be true. For years scientists have experimented with various methods of capturing the abundant energy radiated from our sun. Today, although far from perfected, solar technology has been advanced to a point where we have learned how to harness and utilize the sun's power. Time, research and money will bring to the market place new products that will be energy savers needed by the entire world.

                              Most of the solar cells in volume production today are made with silicon. this plentiful natural resource makes up more then one fourth of the earths crust and is the chief component of ordinary sand. The silicon used in the production of solar cells must be purified to a very high degree.

                              When sun shine penetrates to the junction of the "N" type and "P" type Silicon cells layers it creates a flow of electrons through the crystal structure.

                              The Crystal structure of silicon contains empty areas which will accept which will accept electrons. As one electron moves to fill a hole, it creates another hole. It is the flow of electrons which produces electricity.

                              Sunlight contains many colors of light. Color and the relative power in each color of light is determined by the measure of the wavelength. Plots the relationship between wavelengths and color along the spectral distribution of ordinary day light.

                             Do not subject the solar cell module to an excessive heat location, as it will warps the plastic lens. Remember, it is not heat that makes your model function, it is light a little experimentation will tell you what setting makes your model work best! Please handle all models with care.
