Solar power generation systems are a green and environmentally friendly energy source, unlike fossil fuels that pollute the environment and increase greenhouse gas emissions. Basically, solar power generation can be divided into two types: photothermal conversion and photoelectric conversion. The following is a brief introduction to these two types of solar power generation systems.
Photothermal conversion
Photothermal conversion refers to the process of directly converting solar energy into thermal energy. This process can be achieved through a solar water heater, which is a device that uses solar energy to heat water. In a water heater, solar energy is absorbed and converted into thermal energy, which is then transmitted to the water supply. Water is heated in a water heater and then used to provide power for the hot water supply in people's daily lives. In addition to solar water heaters, other solar thermal conversion systems also include solar air conditioning and cooking equipment.
photoelectric conversion
Photoelectric conversion refers to the process of converting solar energy into electrical energy. This process can be achieved through solar cells (also known as solar photovoltaic cells). When solar energy rays directly shine on solar cells, photons interact with semiconductors to generate current. This process is called the solar photovoltaic effect. Solar cells are one of the most widely used solar power generation systems in practice, and they can be installed on roofs, floors, and rooftops to generate clean electricity.
