Spectrophotometer for the characterization of receivers of solar collectors in order to determine optical properties (transmittance and reflectance). The equipment allows the evaluation of a receiver tube in real time and in any kind of light conditions, both inside and outside. The equipment also allows the detection of the eccentricity between the outer tube and the inner tube, which directly influences the reliability of the measurement. The equipment has a mechanical system for allowing a rotation of the equipment around the tube in order to find the optimum measurement position and attach itself to the tube.

A method is provided for producing a visual hydrogen sensor and to a sensor produced in this manner, the sensor allowing the presence of hydrogen gas in a medium to be detected by the naked eye as a result of a change of color in the sensor. The method involves the deposition of thin porous layers of oxides that do not absorb visible light in their completely oxidized state which become colored when they are partially reduced. This deposition is carried out using vapor phase deposition (PVD) in a glancing angle configuration (GLAD). The method also involves the preparation of a solution of an active metal precursor capable of dissociating the hydrogen molecule and a carrier vector and the deposition of this solution on the oxide layer in order to incorporate a minimum quantity of active metal within the pores of the oxide layer in the form of nanoparticles.

Selective solar absorbent coating and manufacturing method, with solar absorption and low emissivity properties. The coating comprises a substrate () of metal, dielectric or ceramic material, at least one highly reflective metal layer () in mid-far infrared applied to the substrate itself which provides low emissivity properties, a mufti-layer structure of alternating dielectric and metallic layers () of subnanometric thickness applied to the reflective metal layer and at least one dielectric layer () that acts as an anti-reflective layer for the solar spectrum. The coating is applicable as a selective absorbent coating in absorbent tubes for parabolic-trough solar collectors, in solar panels for hot water, heating or domestic cooling, both in the form of absorbent tubes and absorbent sheets, in capture systems in tower solar thermoelectric power plants, and in capture systems in Stirling disk systems.

System for supporting an evaporable getter, which can be installed in any type of solar power receiving tube and which is mounted using an automated method. The system consists of a clip-type supporting element having a substantially thin profile and an S-shaped base, the upper part thereof including a ring in which the pellet of evaporable getter is housed. The pellet is supported by the pins of the supporting element, dispensing with the need for an additional contact part in order to secure the pellet. The clip is secured to the bellows-type expansion compensator, such that it remains inside the vacuum zone of the solar power receiving tube.

Superheated steam tower receiver with a well-defined configuration that benefits the transfer of heat between the surface of the component and the working fluid. Composed of at least four subpanels that define the circulation circuit for the steam by means of internal passages. The component is provided with saturated steam and for the production of said steam it is possible to use other solar concentrator technology. The proposed configuration minimizes the technological risks inherent in superheated steam receiver technology where drawbacks arise in the structure of the material owing to the thermal cycles to which the solar component is subjected.

New expansion compensating device and manufacturing method of the same, of those used in solar power absorber tubes featuring a dual bellows design where the height of the waves of the bellows is not regular, but the second wave is greater (where it supports more load) and diminishes towards the ends. With this design improving the performance of the receiver is achieved because it shortens the length of the device and consequently there is more surface area receiving solar radiation as well as it decreases the necessary diameter of glass tube and therefore its cost.
