Solar Photovoltaic Sputtering Targets

The Thin film photovoltaic, solar sputtering targets thermal and concentrated solar power systems offer great alternatives for the energy requirements of the future. To improve the efficiency of solar systems, it is essential that high-grade materials are sourced. DX Advanced Materials Co offers various high purity sputtering targets.

sputtering-targets-for-solar-photovoltaticA thin-film solar cell (TFSC), also called a thin-film photovoltaic cell (TFPV), is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous and other thin-film silicon (a-Si, TF-Si).
A copper indium gallium selenide solar cell or CIGS cell uses an absorber made of copper, indium, gallium, selenide (CIGS), while gallium-free variants of the semiconductor material are abbreviated CIS. It is one of three mainstream thin-film technologies, with a lab-efficiency above 20 percent and a share of 2 percent in the overall PV market in 2013. Traditional methods of fabrication involve vacuum processes including co-evaporation and sputtering, and rotary magnetron sputtering technology is used in all major forms of solar cell technology.Solar Photovoltaic coating sputtering targets

Solar coating sputtering targetsHigh purity silicon crystals are used to manufacture solar cells. The crystals are processed into solar cells using the melt and cast method. The cube-shaped casting is then cut into ingots, and then sliced into very thin wafers.
Processing wafers
Silicon atoms have four “arms.” Under stable conditions, they become perfect insulators. By combining a small number of five-armed atoms (with a surplus electron), a negative charge will occur when sunlight (photons) hits the surplus electron. The electron is then discharged from the arm to move around freely. Silicon with these characteristics conducts electricity. This is called an n-type (negative) semiconductor, and is usually caused by having the silicon ‘doped’ with a phosphorous film.

In contrast, combining three-armed atoms that lack one electron results in a hole with an electron missing. The semiconductor will then carry a positive charge. This is called a p-type (positive) semiconductor, and is usually obtained when boron is doped into the silicon.
