A SURVEY OF SELECTIVE SOLAR ABSORBERS AND THEIR LIMITATIONSD.M. Mattox et R.R. Sowell

A number of materials and techniques have been used to form selective solar absorber coatings. Each of the coating processes and the coatings formed has its own limitations which are generally poorly defined. The poor state of knowledge on the limitations of the coating processes and the resulting coatings poses a problem for the component design and the materials engineer. This paper reviews the state of knowledge of some of the coating processes and materials being used and of potential usefulness in mid-temperature solar-thermal collectors. A principle point that is made is the lack of production experience and knowledge of the degradation modes for most of the coating technologies and coating material.
