|By using semiconducting material, and putting 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
an touchable switch is available. Moreover, it is convenient to take when traveling.
