Abstract

The invention provides a passive optical label and an optical identification label system; a high efficiency back-contact photovoltaic battery assembly is employed in a passive optical label; a circuit board with an interdigital electrode is designed so as to realize cascaded and parallel arrangement of a plurality of photovoltaic cells, so the photovoltaic cells in a small area can realize a highoutput power, thus improving the optical signal energy conversion efficiency. The output power of an existing optical label can be reduced when being minisized, so a luminous energy emission module in the optical label cannot emit a needed optical signal, thus affecting the stability of the optical identification label system; the passive optical label can solve said problems, thus greatly expanding the application scope of the optical identification label system.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a passive optical label and an optical identification label system. Background technique [0002] With the development of Internet of Things technology, radio frequency identification (Radio Frequency Identificon, RFID) technology has received more and more attention. The RFID system uses radio frequency electromagnetic waves as the medium for data reading and writing between the reader and the electronic tag. Due to the divergence of the propagation direction of radio frequency electromagnetic waves and the susceptibility to interference from metals, the range of RFID use is limited. Optical identification technology is a new type of label identification technology. It uses optical signals to read and write data labels. Because of the directionality of optical signal propagation, the system does not need to use radio frequency electromagnetic waves, so that the data lab...
