Photovoltaic power generation.
In theory, photovoltaic power generation technology can be used in any occasion where power is required, from spacecraft, down to household power, to megawatt power stations, small to toys, and photovoltaic power everywhere. The most basic components of solar photovoltaic power generation are solar cells (sheets), such as monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. Among them, single crystal and polycrystalline batteries have the largest amount, and amorphous batteries are used for some small systems and calculator auxiliary power supplies. At present, the efficiency of polycrystalline silicon cells is about 16% to 17%, and the efficiency of single crystal silicon cells is about 18% to 20%. A solar panel consisting of one or more solar cells is referred to as a photovoltaic component. Photovoltaic power generation products are mainly used in three aspects: one is to provide power for non-electrical occasions; the other is solar energy daily electronic products, such as various types of solar chargers, solar street lamps and solar lawns, etc.; This has been widely implemented in developed countries. By 2009, China's grid-connected power generation has not yet begun to be fully promoted. However, part of the 2008 Beijing Olympic Games was powered by solar power and wind power.
