Copper Indium Selenide (CIS) is a high-performance semiconductor material for field effect transistors and solar cells, which is an important downstream

Copper indium selenide, abbreviated as CIS in English, with the molecular formula CuHInSe2, is a ternary compound and one of the main copper indium compounds. It is a high-performance I-III-VI semiconductor material with stable physical and chemical properties and high light absorption coefficient. , high photoelectric conversion efficiency and other advantages, it can be used as sputtering target material, infrared luminescent material, etc., and is widely used in field effect transistors, thin film solar cells and other manufacturing fields.
Field effect transistor (FET) is a voltage-controlled semiconductor device that uses electric field effect to control current. It has the advantages of high input resistance, no secondary breakdown, and low power consumption. Traditional field effect transistors are made of polycrystalline silicon or monocrystalline silicon and cannot be applied to flexible devices. Copper indium selenide can be sputtered to obtain thin film materials to manufacture thin film field effect transistors. The performance of this field effect transistor is improved, and it has the advantage of good flexibility and a wider range of downstream applications.
MOS tubes are an important product type of field effect transistors, and their market demand has been growing since 2015. In 2021, the global MOS tube market will reach 42.85 billion yuan, of which China’s MOS tube market share will reach 46%. It can be seen that the development trend of my country and the global field effect transistor market is good. As the technology of smart wearable devices and other flexible electronic products continues to advance and the scale of production continues to expand, thin film field effect transistors have greater development potential, which is beneficial to the development of the copper indium selenide industry.
According to the“China Copper Indium Selenium (CIS) Industry Market In-depth Research and Development Prospects Forecast Report 2022-2027” released by the Industrial Research CenterShow that thin-film solar cells use thin films sputtered from high-performance semiconductor materials as light-absorbing layers. They have the advantages of high photoelectric conversion efficiency and good flexibility, and have become an important development direction of solar cells. Copper indium selenide is one of the light-absorbing layer materials of thin-film solar cells, and can be sputtered on the substrate to a film with a thickness of micrometers to nanometers. In addition to the advantages of high photoelectric conversion efficiency and good flexibility, copper indium selenide thin film solar cells also have the characteristics of low manufacturing cost and strong radiation resistance, and have great development potential in the building integrated photovoltaic (BIPV) market.
In 2021, global thin-film solar cell production will reach 8.3GW, continuing to maintain a growth trend. In order to improve the photoelectric conversion efficiency of solar cells and meet the market demand for distributed photovoltaics and building-integrated photovoltaics, my country’s thin-film solar cell industry has entered a stage of rapid development since 2009, with output continuing to grow. However, crystalline silicon solar cells currently still dominate. The penetration rate of thin-film solar cells in the global market is around 4%, and the penetration rate in the Chinese market is around 5%. This limits the development of the copper indium and selenium industry to a certain extent.
Industry analysts said that from the perspective of the high-performance semiconductor material market with high light absorption efficiency, cadmium telluride occupies a dominant position and is The main material for manufacturing thin film solar cells; from the perspective of the copper indium compound market, copper indium gallium selenide has attracted more attention and has more technical and application research results. However, the photoelectric conversion efficiency of copper indium selenide is in a leading position among various thin film materials, so it still attracts many scientific research institutions and enterprises to enter the layout. Globally, copper indium selenium related manufacturers mainly include American Elements, ALB Materials Inc, QS Advanced Materials, etc.
