Space Solar Cells Drive Rapid Growth In Market Demand For Germanium Substrates

Space solar cells drive rapid growth in market demand for germanium substrates

 

Germanium substrate single-chip solar cell is a new functional material that has emerged with the continuous development of the aerospace industry in recent years. High-efficiency multi-junction solar cells using germanium wafers as substrates are mainly used in space power supplies such as satellites, that is, space photovoltaic power generation. , and can also be used for ground concentrated photovoltaic power generation.

Compared with traditional substrate materials, germanium substrates are resistant to cosmic high-energy ray radiation and have high photoelectric conversion efficiency. Currently, germanium substrates (2-inch, 3-inch, 4-inch, 6-inch) are mainly used in solar photovoltaic cells and high-performance light-emitting diodes and other device products in the aerospace field.

Due to the scarcity and preciousness of germanium, many countries have listed it as a strategic resource. The world's proven germanium reserves are about 8,600 tons. China is one of the world's major germanium resource distribution countries, with proven germanium reserves of 3,500 tons. Left and right, mainly distributed in Inner Mongolia, Yunnan, Guangdong, Jilin, Shanxi, Sichuan and Guizhou. Due to the scarcity of germanium resources, the germanium substrate industry has high entry barriers.

According to the "China's Germanium Substrate Market Analysis and Development Prospects Research Report 2024-2028" released by the New Thinking Industrial Research Center, the demand for germanium substrates in the space energy field is stable and closely related to the total number of satellite launches. This is mainly because the increase in the number of spacecraft launches, including artificial satellites, has benefited the space-use germanium substrate gallium arsenide solar cell industry, thus promoting the rapid growth of the market demand for germanium substrates. From a global perspective, the germanium substrate market is highly concentrated, with companies represented by Umicore and Beijing Tongmei Crystal Technology Co., Ltd. occupying a larger share of the market.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Germanium substrate solar cells have application advantages not only in artificial satellites, but also in space stations, space probes and other fields. Driven by this background, the number of spacecraft launches from China, the United States and other countries continues to increase, prompting the space solar cell market to achieve substantial growth. Therefore, the good development of the space solar cell industry has greatly promoted the growth of the market demand for germanium substrates.

The rapid development of the information technology industry will create a very large demand for semiconductor materials, which are the underlying support of this industry. In particular, new high-performance semiconductor materials based on gallium arsenide, indium phosphide, and germanium crystal materials have a very high demand. Good market prospects. Regarding the germanium substrate market, in addition to international competitors, there are also companies in my country that are gradually entering the germanium substrate industry, such as Guangdong Advanced Materials Co., Ltd., Yunnan Lincang Xinyuan Germanium Industry Co., Ltd., etc.

Industrial research

People believe that with the continuous rise of enterprises related to my country's germanium substrate industry chain, independent production will gradually be realized in large-size crystal growth technology, leading China's germanium substrate industry to break through the situation where foreign-funded enterprises dominate the global market. This will then change the current competitive landscape of the domestic germanium substrate market.
