Molybdenum Sputtering Target for Solar Cell

Solar cells are designed to convert (at least a portion of) available light into electrical energy.

Molybdenum sputtering target used in solar system is always in rectangle shape in the first layer which is deposited by sputtering on the soda-lime glass substrate. Molybdenum sputtering target is also the back contact of the CIGS solar cells.

Molybdenum sputtering target is used in solar system because of its low thermal expansion and high corrosion resistance. Molybdenum sputtering target is the first layer of solar cell, it is exposed to sun, rain, and so on. So it needs special material to protect the solar system in operation and using age. Solar system is to convert sunshine into energy. Thus, the ability of deposition is needed, and molybdenum sputtering target possesses the advantage.
