Solar Energy LCD Key Chain
|The solar cell s main principle is through the use of semiconducting material, and |
put the thinner model N semiconductor on the thick P semiconductor. When the photon
hitting the surface of this equipment, the adjoining plane of the model P
and model N semiconductor will create the electron scattering to produce the electric
current. The electric current can be stored up in the accumulator. It does
not need to replace the battery, and a touchable switch is available. Moreover,
it is convenient to take when in travel.
