Generally, bacteriochlorophyllides were responsible for the photosynthesis in bacteria. Seven types of bacteriochlorophyllides have been disclosed. Bacteriochlorophyllides a/b/g could be synthesized from divinyl chlorophyllide a. The other bacteriochlorophyllides c/d/e/f could be synthesized from chlorophyllide a. The chemical structure and synthetic route of bacteriochlorophyllides were summarized in this review. Furthermore, the potential applications of bacteriochlorophyllides in photosensitizers, immunosensors, influence on bacteriochlorophyll aggregation, dye-sensitized solar cell, heme synthesis and for light energy harvesting simulation were discussed.
Using energy-harvesting technology can make the work scope of passive radio frequency identification tag to achieve the maximum .The study put forward to collecting light from the solar cell share tag antenna area, that provides the power source except from the reader receive to electromagnetic power ,which to activate the label circuit. In order to make solar cell to the influence of the tag antenna to minimum ,so optimize it with electromagnetic simulation on its position .The collected dc power could convert into the radio frequency with the efficient E-class oscillator , as well as it could flow into the radio frequency identification tag terminal with the aid of the proper designed coupled circuit .The oscillation frequency is selected on the principle of not affecting the operation of label back scattering .The presented oscillator is showed in the simulations .The E-class oscillator is used together with other forms of collection technology ,such as thermoelectric collect machine.
