Different energy sources must rely on different power generation devices to convert them into electricity. Power generation devices mainly include chemical batteries, solar arrays, nuclear energy, and solar power systems. Only the commonly used solar cells are introduced here.
A solar cell is a semiconductor device that directly converts light energy into electrical energy, and is the basic component of a solar cell array. There are many types of solar cells that can be used in spacecraft, including amorphous silicon solar cells, monocrystalline silicon solar cells and compound cells of group III-V elements (gallium arsenide solar cells). At present, the most widely used solar cells are silicon solar cells and single-junction and triple-junction gallium arsenide solar cells with germanium as the substrate. Conversion efficiency is an important parameter of solar cells, which is used to measure the power output level of solar cells. The higher the conversion efficiency, the better the performance of the cell.
