Summary of "Development of Sn doped ZnO based ecofriendly piezoelectric nanogenerator for energy harvesting application."

In this work, we have demonstrated Zinc Oxide (ZnO) polymer-based ecofriendly piezoelectric nanogenerator (PENG) on a paper substrate for energy harvesting application. The ZnO thin film is developed on the paper substrate, where different doping concentrations of Sn have been investigated systematically to validate the effect of doping towards enhancing the device performance. The piezoelectric potential of the fabricated device is evaluated by applying three different loads (4 N, 8 N, 22 N), where the source of corresponding mechanical loads is based on the drum stick musical instrument. The results suggest that the pristine ZnO PENG device can generate the maximum output voltage and current of 2.15 V and 17 nA respectively. Moreover, the ZnO PENG device doped with 2.5% Sn achieve even a higher voltage (4.15 V) and current (36 nA) as compared to pristine ZnO devices. In addition to, the hydrothermal growth technique used to develop Sn doped ZnO possess high scalability and low-cost benefits. Hence, Sn-doped PENG device can be a suitable candidate for energy harvesting application operating in both uniform and non-uniform loading conditions.

Medical and Biotech [MESH] Definitions

Light energy harvesting structures attached to the THYLAKOID MEMBRANES of CYANOBACTERIA and red algae (ALGAE, RED). These multiprotein complexes contain pigments (PHYCOBILIPROTEINS) that transfer light energy to chlorophyll a.

An analytical transmission electron microscopy method using an electron microscope fitted with an energy filtering lens. The method is based on the principle that some of the ELECTRONS passing through the specimen will lose energy when they ionize inner shell electrons of the atoms in the specimen. The amount of energy loss is dependent upon the element. Analysis of the energy loss spectrum (ELECTRON ENERGY-LOSS SPECTROSCOPY) reveals the elemental composition of a specimen. It is used analytically and quantitatively to determine which, how much of, and where specific ELEMENTS are in a sample. For example, it is used for elemental mapping of PHOSPHORUS to trace the strands of NUCLEIC ACIDS in nucleoprotein complexes.
