List of Sputtering Targets for Solar Cell Coating
views, Updated: 2021-09-14
Solar energy is mainly used to convert solar energy into heat and electricity. The photoelectric conversion is identified by the solar cell, which directly converts the light energy into electric energy through the photoelectric effect. At present, the solar cell has developed to the third generation. The first generation is monocrystalline silicon solar cells. The second generation is amorphous silicon and polycrystalline silicon solar cells. The third generation is thin-film solar cells (represented by CIGS).
The sputter coating process is preferred for solar energy coating. With the rise of the global low-carbon economy, solar cells get blowout development. But the solar cell coating grows explosively. Subsequently, the demand for solar sputtering target materials is also increasing.
The sputtering target materials for solar cell coating mainly include AZO sputtering target, ZnO sputtering target, ZnAl sputtering target, Mo sputtering target, CdS sputtering target, CuInGaSe sputtering target. Further details are as follows:
AZO Sputtering Target
AEM Deposition specialized in producing high purity Aluminum-doped Zinc Oxide (AZO) Sputtering Targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD), and physical vapor deposition (PVD) display and optical applications. Our standard sputtering targets for thin-film are available monoblock or bonded with planar target dimensions and configurations up to 820 mm with hole drill locations and threading, beveling, grooves, and backing designed to work with both older sputtering devices as well as the latest process equipment, such as large-area coating for solar energy or fuel cells and flip-chip applications. Research sized targets are also produced as well as custom sizes and alloys.
Zinc Oxide Sputtering Target
Zinc oxide is an inorganic compound with the formula ZnO. ZnO is a white powder that is insoluble in water. It is widely used as an additive in numerous materials and products, including rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first-aid tapes. Although it exists naturally as the mineral zincite, most zinc oxide is produced synthetically.
Molybdenum Sputtering Target
Molybdenum is a silvery-grey metal with a Mohs hardness of 5.5. Its melting point is 2,623 °C (4,753 °F). Only tantalum, osmium, rhenium, tungsten, and carbon have higher melting points between the naturally occurring elements. Weak oxidation of molybdenum starts at 300 °C (572 °F). It has one of the lowest coefficients of thermal expansion among commercially used metals. Molybdenum wires' tensile strength increases about three times, from about 10 to 30 GPa, when their diameter decreases from ~50–100 nm to 10 nm.
Cadmium Sulfide Sputtering Target
Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite. But it is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium. As a compound that is easy to isolate and purify, it is cadmium's principal source for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century.
AEM Deposition, as a sputtering target manufacturer, we provide not only sputtering targets for glass but also sputtering targets for other fields. Such as pure metal sputtering target, alloy sputtering target, ceramic oxide sputtering target and so on. Further details are as follows:
