On May 11, Tianzhou 10 cargo spacecraft was successfully launched from Wenchang Space Launch Site in Hainan. Whose is the space battery of Tianzhou 10? Affordable space photovoltaic is really coming this time! The
answer is that it is a gallium arsenide battery developed
by the Shanghai Institute of Microsystems and Information Technology of the Chinese Academy of Sciences for three years. It is hard and heavy, and the cost of one square meter is comparable to gold; Now this new type of flexible monocrystalline silicon heterojunction solar cell is only 80 microns thick, so thin that it can be rolled, less than 1 kilogram per square meter, and the cost is directly reduced to 1/10 of the original!
God is not for show! It has to rotate outside the cabin, withstand the most extreme test of space, find out the attenuation law, and explore the way for the million-level satellite network!
This is not an ordinary battery, but a parity revolution in China's commercial space industry! In the past, "space electricity = burning gold", but now with it, the cost of satellite networking and space computing power is directly cut to one tenth, and the parity of space photovoltaic is really close!
From laboratory to space, China's photovoltaic hard power is rewriting the rules of space energy! Thumbs up for Chinese science and technology!
