PURPOSE:To provide a function of an electric charger to a cell itself, by integrally forming a solar cell to the peripheral part of a secondary cell to both connect the cells of the same polarity and provide a switch opened and closed by weight of the cell. CONSTITUTION:A solar cell 2 and secondary cell 1 are integrally formed to the periphery of the cell 1. Then the cells of the same polarity are electrically connected while a switch 5 turned on by a bed 6 with empty weight 7 of the cell 1 is connected between the cells. Accordingly, the cell, if only placed in an area irradiated by light of the sunbeams or the like, can be charged even without a different charger device or power source, and limitation of a charging place or time can be largely reduced. |
