Ziel
- To optimise optical and thermal properties for coatings to be used in the most popular conversion systems as well as in more prospective ones;
- To improve durability of the materials, bearing in mind the possibility of high temperature degradation of selective absorbers;
- To develop-non polluting (CrVI) - industrially feasible, - relatively not expensive, -versatile processes of preparation;
- Preparation at pilot scale of coatings for assessment in solar panel (x dm2) under real conditions (degradation of the efficiency, effect of the external parameters, etc.).
Results so far
- We improved the homogeneity of the Te films, found PbS to be a good shield material and have started the test of the cooling devices.
- Photothermal Radiometry (PTR) has been applied in order to investigate the IR emission, of thin silicon nitride films. PTR was also applied and demonstrated as a non-destructive technique for the evaluation of solar selective coatings. The photothermal technique can easily be implemented in industry for in-line characterisation during production.
- FTIR Spectroscopy was also used to provide a qualitative description of the behaviour of the films in the IR range that shows favourable properties of these coatings to be used in passive cooling applications.
- It has been shown that the theoretical one dimensional model that is used to fit the experimental PTR results, is allowing the extraction of some key parameters of the solar absorbing coatings.
- Optical refractive indices were collected and by using regression techniques, complex dispersion equations were formulated and stored in the programme library.
