Detailed Product Description
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. Packing: Blister + paper card It can be designed according to clients' demands
