Solar windsurfing on satellites (expanded) Solar windsurfing is a device for collecting solar energy, usually used for the supply of satellites and spacecraft, and also for installation on top of environmentally friendly cars. The basic principle of solar panels is to use the photoelectric effect of metals such as silicon (Si) to convert solar energy into electrical energy, which is then stored in solar cells of satellites, spacecraft, and electric vehicles.
The important energy power components on the "Shenzhou VI" - solar wafers, are all provided by Wanxiang Silicon Electronics Co., Ltd., a subsidiary of Wanxiang Group. After the Shenzhou-6 manned spacecraft and the launch vehicle were separated into the orbit, a pair of solar panels on the spacecraft unfolded smoothly. Solar panels have two functions of power supply and charging, which is equivalent to a small power station. Before the spacecraft enters the track, a pair of small solar panels are folded and fixed on both sides of the orbital module, and the other pair of large folds are fixed on the bulkhead outside the propulsion compartment. In the lift-off phase, in order to protect them from the oncoming aerodynamic flow, the solar panels are folded in the fairing until the spacecraft enters the orbit. The silicon wafer on the solar panel is “universal manufacturingâ€.
According to reports, since many test instruments on the spacecraft rely on electricity as an energy source, the normal deployment of solar panels is a key action in spacecraft flight. Although the spacecraft's solar panels use a lot of advanced technology, however, due to the large area and relatively complex structure, there are still certain risks when it is deployed in space. The two pairs of solar panels on the spacecraft were launched smoothly, providing sufficient power for the multi-day space tour of the Shenzhou-6 manned spacecraft.
The relevant person in charge of Wanxiang Group told the reporter that Wanxiang Silicon Peak Electronics Co., Ltd. is a national key high-tech enterprise. The silicon single crystal and silicon wafer produced by the company are reliable in quality, stable in performance, high in photoelectric conversion efficiency, and many are launched by China. The satellite and the Shenzhou-1, 2, 3, and 4 spaceships are used by the Shenzhou-5 manned spacecraft. The Shenzhou-7 manned spacecraft launched in September 2008 also used solar panels.
A solar cell is a device that directly converts light energy into electrical energy through photoelectric effect or photochemical effect. He is similar to solar windsurfing. Solar windsurfing is not the same thing as solar sails. Solar windsurfing is a device for collecting solar energy, and solar sail is a spacecraft that uses the light pressure of sunlight to conduct space.
