In recent years, the problem of environmental pollution has been raised very seriously due to the increase of greenhouse gas due to the use of petroleum energy. In order to prevent global warming, efforts to reduce the emission of carbon dioxide are accelerated around the world .

As a result, there is a growing interest in the development of alternative energies using environmentally friendly sunlight, wind, and tidal energy without causing environmental pollution. Especially, Development of devices for producing heat sources necessary for hot water, heating and the like as well as energy production is actively progressing.

On the other hand, wind power generation, hydro power generation, and tidal power generation are more efficient than photovoltaic power generation, but they are limited in installation area, and there is a problem in that the mechanical equipment or configuration to be installed is complicated, This is a trend that is not economically feasible.

Therefore, solar energy using solar energy or solar energy in environment-friendly energy is environmentally friendly, and research and development are progressing rapidly due to the fact that there is no depletion of resources.
