In the global context of addressing climate change and driving digital transformation, silicon's value transcends the traditional semiconductor field, becoming a bridge connecting green energy and smart technology. On one hand, high-purity silicon is a core material for photovoltaic power generation, converting sunlight into clean electricity; on the other hand, it serves as the substrate for chips, supporting a digital ecosystem from artificial intelligence to the Internet of Things. Understanding silicon's dual role is key to understanding the technological path to sustainable development. Our "Uses of Silicon" exhibit invites visitors to explore the diverse applications of this material through a 3.5-meter-wide multimedia interactive platform. You can switch between solar cell and microchip manufacturing processes via a rotating wheel, watching vivid projection animations explain the mysteries of silicon crystal growth and circuit etching. The touchscreen provides full lifecycle.
