A Spark of Light

Hall Three ▪ Craftsmanship

In 2001, Dr. Shi Zhengrong returned to China to establish Suntech. By 2005, China's solar module production accounted for only 11% of global output, and its polysilicon production represented a mere 0.3% of the world's solar-grade silicon consumption.

2001-2005

Venturing into Photovoltaics

In 2003, the company imported two Meyer Burger slicing machines from Switzerland, marking the official start of its journey in pursuit of solar innovation. It became the pioneer in introducing crystalline silicon multi-wire slicing technology to China.

The Darkest Hour

In 2008, the global financial crisis cast a shadow over the world, and Western nations began scaling back photovoltaic subsidies. By 2012, the U.S. and Europe imposed anti-dumping ("double anti") measures and additional tariffs on Chinese PV products.

2008-2012

Overcoming Challenges

In 2006, the company initiated cooperation with MEMC through OEM services. By 2010, it had co-founded Meike Silicon Energy and proactively expanded into overseas markets, establishing a customer base across South Korea, Malaysia, Norway, India, and beyond.

Industry Transformation

In 2015, the adoption of diamond wire cutting technology accelerated the growth of the monocrystalline market share. By 2018, the "5.31" policy introduced by the National Energy Administration marked a turning point, with monocrystalline replacing polycrystalline as the dominant industry direction.

2015-2018

Meike's Strategic Shift

Starting in late 2017, the company conducted multiple site visits to Baotou, Leshan, and other regions. In July 2018, Baotou Meike was established in Kundulun District, Baotou City, Inner Mongolia, focusing on monocrystalline ingot production. Once again, Meike achieved a remarkable transformation.

In September 2020, President Xi Jinping announced China's ambitious goals of achieving "carbon peak" by 2030 and "carbon neutrality" by 2060.

2019 to today

Embracing the "Dual Carbon" Era

Meike is forging ahead with the strategic objectives of the 14th Five-Year Plan, striving to become the world's most influential silicon wafer supplier.

Industrial Silicon

Improved Siemens polysilicon

If quartz and charcoal are mixed and heated to above 1900°C, electrolysis can produce more than 98% silicon, known as metallurgical-grade silicon. Because it contains some metals, it is also referred to as metallic silicon or silicon metal. This silicon material can be further purified to produce higher purity silicon (polysilicon), which is used in the manufacturing of crystalline silicon solar cells.

The Siemens process for polysilicon production involves using high-purity hydrogen to reduce trichlorosilane on a high-purity silicon core at around 1100°C, producing polysilicon that deposits onto the silicon core. The improved Siemens process not only maintains traditional production but also incorporates energy-saving measures, reduces consumption, and recycles byproducts like H₂, HCl, and SiCl₄, as well as large amounts of heat energy. Most polysilicon manufacturers around the world use this improved Siemens method. It is the most mature, widely applied, and fastest-growing technology for polysilicon production.

Granular Silicon Obtained from Siliane FBR Method

Granular silicon is produced via the Fluidized Bed Reactor (FBR) method using silane. This method has relatively low production costs. Granular silicon increases the packing density of silicon materials, enhancing production efficiency. Its excellent flowability makes it suitable for continuous feeding and has become widely used in the industry.

Czochralski Method

Diamond Wire Slicing Technology

The Czochralski method is used for crystal growth. Polycrystalline silicon is loaded into a quartz crucible and melted at around 1500°C. Through processes such as seed growth, necking, shoulder forming, diameter control, and tailing, uniform single-crystal silicon rods are grown. After cooling, the silicon rod is cut, squared, and polished to the required dimensions, then mounted on rails and plastic plates for cutting.

Diamond wire slicing involves using a specialized slicer with high-speed reciprocating diamond wire, which grinds against the silicon rod under pressure, enabling efficient cutting. Compared to traditional slurry cutting, diamond wire slicing offers faster cutting speed, higher precision, and lower material loss. After slicing, the silicon wafers are placed in ultrasonic cleaning machines to remove surface impurities. Meike uses 100% advanced silicon wafer sorting machines to inspect and sort the wafers based on appearance, thickness, resistivity, TTV, and warpage, packaging them according to grade and shipping requirements.

High Efficiency P/N Type Mono Wafer

Photovoltaic systems are typically classified into off-grid, grid-connected, and hybrid systems. In recent years, the global installed capacity of solar power has grown rapidly, surpassing 800GW by 2021. Against the backdrop of carbon peaking and carbon neutrality, the International Renewable Energy Agency (IRENA) predicts that by 2050, renewable energy will account for 90% of global power generation, with solar and wind power accounting for 63%, and global photovoltaic installed capacity exceeding 14,000GW.
