Advancement in thin-film battery technology, CIGS has gradually emerged

The development of the industrial revolution has led to a large-scale increase in demand for metals, and the emergence of current emerging industries has also led to a surge in the demand for some rare metals. In recent years, with the rapid development of the thin-film solar industry, the sub-technical route - copper Indium gallium selenide (CIGS) has gradually emerged.

The copper Indium gallium selenide thin-film solar cell has the remarkable characteristics of low production cost, low pollution, no degradation, and poor light performance. The photoelectric conversion efficiency is the first among various thin-film solar cells, close to the crystalline silicon solar cell, and the cost is only its One-third, known as the next generation of new thin-film solar cells, is a hot spot in research and development in recent years. Rare precious metals such as Indium, selenium, and gallium are key raw materials for copper indium gallium selenide thin-film solar cells. As one of the important raw materials for making copper indium gallium selenide batteries, the demand and price have increased rapidly. In the preparation process, the form of Indium used in different methods is also different. The Indium used in the sputtering method is a target of high purity Indium of 6N or more, and the Indium used for co-evaporation is a high purity Indium particle of 6N or more.

According to statistics, the global proven reserves of Indium are estimated at 50,000 tons, of which 50% can be mined. The industry produces metal Indium by purifying waste Zinc and waste Tin, and the recovery rate is about 60-70%. From this calculation, based on the proven reserves, the increase in recoverable amount and the indium recovery rate, the currently available Indium is about 15,000 tons to 18,000 tons. At this stage, Indium does not constitute an influence on the application of copper Indium gallium selenide. According to analysts, "18,000 tons of Indium can be used. If all copper Indium gallium selenide batteries are produced, it can produce 1800 GW. Even if only one-tenth of the amount is used to produce copper Indium gallium selenide, it can produce 180 GW. In terms of current copper Indium gallium selenide production capacity, Indium resources are still very rich."
