At 7:30 on October 17, 2016, an exciting event happened! All Chinese people know that it is - Shenzhou 11 is on the sky!
This historic moment, how can patriot creation be missed! Haha, everyone has been constantly scanning live broadcasts, and Chuangchuang has been watching this moment on the observatory of the small planet! Because this is the sixth manned mission in China, and it is the longest duration. The aerospace heroes and uncles will fly in space for 30 days. Just at 3:31 on the 19th, the spacecraft and the Tiangong 2 Space Laboratory will automatically rendezvous and connect successfully! The two astronauts and uncles also successfully entered the experimental cabin of the Tiangong-2 from the Shenzhou 11 spacecraft.
What makes the creation of chickens frozen is that the power supply for the Shenzhou 11 flight is solar battery windsurfing! And around the spacecraft, an energy storage battery is also installed! what? What does God mean? That is to say, photovoltaic is also going to heaven!
Do you make it? The Shenzhou 11 spacecraft has installed a total of 8 solar panels! Each half board is 3 square meters, a total of 24 square meters. And the battery used is still a high efficiency GaAs solar cell! At the same time, the staff also prepared energy storage batteries for the spacecraft to ensure normal power supply to the spacecraft when facing away from the sun. According to the knowledge acquired by Chuangchuang, GaAs solar cells are high-energy batteries with high efficiency, light weight, small area and strong anti-irradiation ability.
This Shenzhou 11 uses a gallium arsenide solar cell with a conversion efficiency of 27.5%, and in the subsequent construction of the space station, it will be converted to a gallium arsenide solar cell with a higher conversion efficiency and can reach 30%. At present, for the use of gallium arsenide solar panels, high-orbit satellites can achieve a 15-year life span, and low-orbit satellites can achieve an 8-year life span.
Chuangchuang also had to mention that the materials used for the substrate from the material to the battery sheet to the entire windsurfing board and the substrate for its manufacture were all manufactured by our own! All have their own intellectual property rights! Our motherland is really getting stronger and stronger, and more and more "international fancier"~
However, for the time being, GaAs solar cells are relatively expensive and cannot be used on the ground. However, by using the "concentrating" method, a concentrating mirror can be added to the solar cell to make 500 times or even 1000 times. The sun shines on the battery, which reduces the cost per watt of the panel. Therefore, the use of GaAs solar cells in the civilian field is also expected!
The spacecraft flew into space, and the solar panels unfolded, helping the spacecraft to swim in space, and the distance between the heavens and the earth was no longer far away. This is the speed of China's development and progress, let us praise the motherland together! Like our hero! I look forward to their triumph!
Even photovoltaics are in the sky, what dreams will not be realized?
