PURPOSE:To obtain practicability by the non-crystal silicon solar battery of a small area in a wireless remote controller large in a consuming power by reducing the area of the solar battery and charging by an irradiating energy from a suitable light source in an electric equipment. CONSTITUTION:When the wireless remote controller 4 having the non-crystal silicon solar battery 3 is inserted to the storing part 2 of a video tape recorder 1 and stored, a push in switch 5 is depressed, a the light source such as a while fluorescent lamp or an LED array is lighted and a visible ray of 10mw/cm<2> is radiated to the solar battery 3 opposite to the light source 6. In this case, as the light source 6, a visible light source having a main light emitting part in 350nm-700nm. Then, at the time of irradiating the light of the white fluorescent lamp of 10mw/cm<2>, the carbon lithium secondary battery 8 of the electric capacity of 1.3mAh with 2V can be charged for 1.2hour. |
