A mobile terminal and controlling method thereof are disclosed. The mobile terminal includes a solar cell module and a selective transmitting member for selectively transmitting light, thereby supplying the light to the solar cell module selectively. Accordingly, since a light-transmitting display and a solar cell module are stacked on each other, the present invention enables a user to appreciate information displayed on the light-transmitting display while enabling the solar cell module to charge a battery. Moreover, since the light having passed through a light-transmitting display can be reflected by a selective transmission member provided between the light-transmitting display and a solar cell module, the present invention is able to enhance readability of information displayed on the light-transmitting display.
