Abstract
A transparent solar heat absorbing apparatus includes a transparent member allowing sunlight to pass through, a wavelength selective member disposed beneath the transparent member, a heating tank formed between the transparent member and the wavelength selective member. The wavelength selective member allows light in a transmission range including at least a visible wavelength range to pass through and reflects light in a reflection range including at least an infrared wavelength range. At least one of the transparent member and the wavelength selective member has a waveform structure on at least one of its upper surface and bottom surface.
