Space solar power generation How to transport huge solar panels into space and assemble them?

Solar cells are devices that use the photoelectric effect of semiconductor materials to convert solar energy into electrical energy: assuming that light shines on the solar cell and is accepted at the level of the interface layer, the photons contain enough photons. energy can In P-type silicon and N-type silicon, electrons are excited by covalent bonds, resulting in the generation of electron-hole pairs. The electrons and holes adjacent to the interface layer will be separated from each other by the result of the space charge electric field before recombination. The electrons move towards the positively charged N region and the holes move towards the negatively charged P region. Through the charge separation of the interface layer, an outward testable voltage will be generated between the P region and the N region. At this point, electrodes can bebe added to both sides of the silicon wafer and connected to a voltmeter. For crystalline silicon solar cells, the typical value of open circuit voltage is 0.5 to 0.6 V. The more electron-hole pairs generated by light hitting the interface layer, the lower the current is high. The more light energy the interface layer absorbs, the larger the surface area of ​​the interface layer, i.e. the battery, and the greater the current formed in the solar cell.
