Title:

SOLAR HEAT COLLECTION TUBE AND PRODUCTION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2017/130534

Kind Code:

A1

Abstract:

The present invention is: a solar heat collection tube (1) in which at least an infrared reflective layer (3), a solar-thermal conversion layer (4), and an antireflection layer (5) are provided on the exterior surface of a tube (2) through which a heat medium can circulate internally; and a production method therefor. The solar heat collection tube (1) is characterized in that the infrared reflective layer (3) is a Ag layer (7) in which silicon, silicon nitride, or a mixture (6) thereof is dispersed. In the production method for the solar heat collection tube (1), Ag and silicon are used as a target and the infrared layer (3) that is a Ag layer (7) in which silicon, silicon nitride, or a mixture (6) thereof is dispersed is formed by performing sputtering in the presence of a gas containing nitrogen gas.
