Abstract

This invention relates to a heat receiver tube for absorbing solar energy and for transferring absorbed solar energy to a heat transfer fluid which can be located inside a core tube of the heat receiver tube. A first part of the core tube surface is covered by a first solar energy absorptive coating for absorbing radiation of a first certain spectrum of the sunlight. A second part of the core tube surface is covered by a second solar energy absorptive coating for absorbing radiation of a second certain spectrum of the sunlight. An emission radiation inhibiting coating for inhibiting an emissivity for infrared radiation is deposited on the second solar energy absorptive coating such that the second solar energy absorptive coating is arranged between the second partial core tube surface and the emission radiation inhibiting coating. The first solar energy absorptive coating forms a first partial heat receiver tube surface and the emission radiation inhibiting coating forms a second partial heat receiver tube surface. Also provided is a parabolic trough collector with at least one heat receiver tube which is arranged in a focal line of a parabolic mirror. The first partial heat receiver tube surface and the sunlight reflecting surface of the mirror are arranged face to face whereas the second partial heat receiver tube surface is averted to the reflecting surface of the mirror.
