[0002]
[Prior art]
Conventionally, when solar power generation is performed, the solar cell alone and the researcher, the heat absorption by the low level warm water by the concentrating solar cell and the jacket on the back surface is measured. In case of cloudy days, the hot water level is low to maintain the efficiency of the battery, the usage of hot water is very limited, and the combination panel of Fresnel lens and concentrating solar cell is used for tracking. Since power generation could not be performed, the power generation amount had a disadvantage compared to the solar cell alone type.
[0003]
Also, when using a single-plate solar cell with a long-wavelength transmission type and collecting heat with the jacket on the back side, if the solar cell on the front surface is in a high temperature range, the power generation efficiency will be significantly reduced. For this reason, the hot water temperature is at a low level.

[Problems to be solved by the invention]
The present invention was made in order to solve the above-mentioned problem, and by collecting light with a condensing lens, it collected light sunlight and separated visible light and long-wave infrared rays to function. In order to reflect visible light, the inner surface of the glass heat collection tube with a concave lens shape is exposed to light by reflecting the visible light on the outer surface and selectively transmitting long-wavelength light. Then, the multi-purpose heat and light separation type condensing power generation device that can heat the internal heat medium at a high temperature, perform turbine power generation using this high temperature, and measure the increase in power generation amount.

[Means for solving problems]
In order to achieve the above object, the present invention collects light with a condensing lens in the case of the solar tracking type, and with a horseshoe-shaped multi-layer integrated lens in the case of the fixed type, and reflects the visible light reflection type long wavelength transmission type. The heat medium is heated by a heat collecting tube, and by this high-level heat medium heating, it is possible to perform turbine power generation with supersaturated steam of a low boiling point solvent and power generation by a concentrating solar cell using reflected light.
[0006]
[Action]
Therefore, both in the case of a sunlight tracking type condensing lens and in the case of condensing by a fixed horseshoe-shaped multi-layer integrated lens, the optical axis installed obliquely above is reflected obliquely with respect to the optical axis. Concentrated power is generated on the back surface of a double-sided power generation type concentrating solar cell in a direction perpendicular to the solar cell so that sunlight can be directly generated on the front surface.
