There is a micro structure on the side of the silicon wafer
The content of silicon in the earth's crust is 25.8%, which provides an inexhaustible source for the production of monocrystalline silicon. Silicon is one of the most abundant elements in the earth's crust,
For solar cells destined to enter the market market (mass) products, the advantages of reserves is also one of the main reasons for the silicon photovoltaic materials.
It is a milestone in the progress of science and technology that 160 thousand transistors have been integrated on a large grain of silicon.
