すことも望めない。Such an energy collector is capable of efficiently recovering solar energy in the form of both heat and electricity, and one of the present applicants has already filed a patent application in Japanese Patent Application No. 55-59663. The most desirable solar cell in this case is an amorphous silicon (a-8i) solar cell, which is easy to manufacture. However, sunlight that is effective for photovoltaic power generation by A-8I solar cells has a wavelength range of 0.3 μm to 0.7 μm, and the wavelength range of 0.7 μm or more cannot be effectively used for conversion into electrical energy by solar cells. . 0.7μm
Most of the solar energy that cannot be converted into electrical energy in the following wavelength range is converted into heat in the a-8i layer, propagated to a heat collector, and used as thermal energy. - Since the absorption rate of A-8i is low for the outside wires of ten thousand notes, it cannot be expected to be extracted as heat.

ことができる。The purpose of the present invention is to provide a solar energy collector that utilizes such infrared rays, which cannot be converted into electrical energy, as thermal energy as efficiently as possible. This is achieved by interposing a layer made of a material with a high absorption rate of infrared rays between the outer surface of the inner tube and the solar cell. For silicon solar cells, amorphous germanium, which has a narrower band gap than Si, or a metal compound such as black alumite, iron oxide, or black chromium can be effectively used as the material for such an intervening layer.
