Simply Efficient

Indium Corporation's CIG alloy sputtering targets, made from copper (Cu), indium (In), and gallium (Ga), are used to produce high-efficiency CIGS (Cu/In/Ga/di-selenide) solar cells. CIG targets offer tight control of the final solar cell composition. This is due to our unique process that results in a fully alloyed and completely homogenous CIG alloy

CIG Alloy Targets have very low levels of impurities, which enable the manufacture of high efficiency solar cells. This is because we can control the impurity levels before and during our manufacturing process.

Targets can be used in reactive or non-reactive modes. Using fully-alloyed targets with various Cu/III and Ga/III ratios enable grading of the deposited CIG chemical composition. This replicates the process used for manufacturing high-efficiency solar cells.

Custom Solutions for High Throughput

CIG AlloyTargets are available in custom shapes, sizes, and alloy composition to suit your unique needs. Consistent, tightly-controlled chemistry throughout the target enable better control on the resulting solar cell chemistry and morphology. In addition, cylindrical, rotatable sputtering targets increase material utilization and system throughput while reducing the total cost of ownership. The cylindrical, rotatable shape offers greater than 70% material utilization with less system downtime and high system throughput.

Other Options

• Absorber layer targets: CuGa, CuIn, and In

• Other common target materials: InSn, InSnO, Sn, SnO, and InZn

• Custom alloys are also available
