General description

Zinc oxide, dispersion (ZnO) is a multi-function metal oxide with unique physio-chemical properties, which includes high chemical stability, broad range absorption spectra and high electrochemical characteristics. It can also be categorized as a semiconductor due to its high energy band width and high thermal stability that make it potentially useful in electronics and optoelectronics applications.

Application

ZnO dispersions have piezo and pyroelectric properties that make it useful in the development of sensors, generators, and photo-catalysis. It has low toxicity and biocompatibility, which facilitate its applications in biomedicine.

One of the more traditional photovoltaic devices, single crystalline silicon solar cells were invented more than 50 years ago, currently make up 94% of the market. Single crystalline silicon solar cells operate on the principle of p-n junctions formed by joining p-type and n-type semiconductors.

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.

Among various ceramics, one-dimensional (1-D) piezoelectric ceramics have attracted significant scientific attention for use in energy harvesting.

Electronically, it behaves as a wide band gap (3.2 eV) semiconductor and exhibits memristor properties.2 Optically, TiO2 has high opacity with a very high refractive index3 (>2.4), and it exhibits strong absorbance in the UV range.
