A charging apparatus and method for charging a battery of a mobile terminal using a thin film printed solar cell. The apparatus has an outer case including electrochromic elements and a thin film printed solar cell. A control unit controls charging of the battery so that a color of the electrochromic elements is changed into a transparent color and sunlight is transmitted to the thin film printed solar cell disposed under the electrochromic elements. Also, the control unit controls charging of the battery such that a color of the outer case is automatically changed into a transparent color so that sunlight is transmitted to the thin film printed solar cell. Also, the color of the electrochromic elements can be changed according to the user's request so that the color of the outer case is changed into a desired color.
