Abstract
An RFID device includes: at least one solar cell including a substrate, a first conductive layer, an electron supplying layer, an electron receiving layer and a second conductive layer sequentially stacked thereon; and a RFID tag coupled to the solar cell through a telecommunication connection structure, and including a first antenna, a second antenna and a RFID chip, and the RFID chip includes a first RFID module, a second RFID module and a radio frequency determination module. The first antenna and the first RFID module are capable of passively receiving a driving signal of an external device and returning tag data, and the radio frequency determination module is capable of automatically determining the external driving signal, and the second RFID module and the second antenna actively transmit the tag data to the external device according to the electric power supplied by the solar CELL.
