Solar panel with optical films

An electronic device comprising:

• a power source;
• electronic circuits, electrically coupled with the power source;
• a solar panel, electrically coupled with the power source;
• and
• a wavelength selectively reflective optical film being disposed in front of the solar panel for the optical film to substantially reflect a pre-selected band of solar irradiation frequencies in the visible light range on a front surface of the optical film while allowing solar irradiation frequencies outside of the pre-selected band to substantially pass through the optical film and irradiate the solar panel.

A wireless device comprising:

• a power source;
• electronic circuits, electrically coupled with the power source, the electronic circuits including a receiver for receiving wirelessly transmitted signals;
• at least one solar panel, electrically coupled with the power source;
• and
• at least one wavelength selectively reflective optical film being disposed in front of the at least one solar panel for the at least one optical film to substantially reflect a pre-selected band of solar irradiation frequencies in the visible light range on a front surface of the at least one optical film while allowing solar irradiation frequencies outside of the pre-selected band to substantially pass through the at least one optical film and irradiate the at least one solar panel.
