Q. Does it include a battery?

Answer: No. We strongly recommend you to avoid products that combine a solar panel with a battery, no matter if it is Li-Po or Li-Ion. Direct exposure to sun may raise the temperature and the battery are not created to be exposed to high temperatures. They will deteriorate and may explode. Photon was build to resist temperatures up to 70° Celsius. Connect the device you want to recharge using a cable and keep it somwhere protected by direct sunlight.

 Q. Can I demage my device if I use Photon?

Answer: No. The electronic circuit incorporates filters that protect your device, no matter what.

 Q. Can I use it under water or during rain?

Answer: Of course not. It was designed to be shower-proof in order to counter the incidental contact with water that inevitable occurs during normal outdoor usage, but this should be avoided as much as possible and special care is required if contact with water occur. Consult the user manual for details. During rain, it is better to store it in your back-pack or in some protected space. It will not work since there is no sun anyway.

 Q. What is a Photon?

Answer: "Photon": according to Wikipedia, is an elementary particle, the quantum of light and all other forms of electromagnetic radiation, and the force carrier for the electromagnetic force. Like all elementary particles, photons are currently best explained by quantum mechanics and exhibit wave–particle duality, exhibiting properties of both waves and particles. For example, a single photon may be refracted by a lens or exhibit wave interference with itself, but also act as a particle giving a definite result when its position is measured. The modern photon concept was developed gradually by Albert Einstein to explain experimental observations that did not fit the classical wave model of light.

 Q. How photoelectric effect works?

Answer: The photons of a light beam have a characteristic energy proportional to the frequency of the light. In the photo-emission process, if an electron within some material absorbs the energy of one photon and acquires more energy than the work function (the electron binding energy) of the material, it is ejected. If the photon energy is too low, the electron is unable to escape the material. Increasing the intensity of the light beam increases the number of photons in the light beam, and thus increases the number of electrons excited, but does not increase the energy that each electron possesses. The energy of the emitted electrons does not depend on the intensity of the incoming light, but only on the energy or frequency of the individual photons. It is an interaction between the incident photon and the outermost electrons.

Electrons can absorb energy from photons when irradiated, but they usually follow an "all or nothing" principle. All of the energy from one photon must be absorbed and used to liberate one electron from atomic binding, or else the energy is re-emitted. If the photon energy is absorbed, some of the energy liberates the electron from the atom, and the rest contributes to the electron's kinetic energy as a free particle
