5. Industry Recognition: Performance and Cost Competitiveness 

BTE Solar's Selective Coating Portfolio BTE Solar offers a diverse portfolio of selective coatings, with a particular focus on blue and black coatings. The blue coatings, known for their distinct color due to interference effects in multilayer oxide structures, are highly regarded for their performance. These coatings are produced using advanced techniques such as electrochemical deposition or sputtering, which allow for precise control over their composition and structure. The blue coatings have excellent optical properties, with absorption rates typically above 95% and emittance values below 5%. This means that they can effectively capture a large portion of the incident sunlight and minimize heat loss, resulting in highly efficient solar collectors. These coatings have found widespread use in Europe and Asia, where they are particularly popular in residential flat-plate collectors. In Europe, the strict efficiency standards, such as EN12975/EN12976, have driven the demand for high-performance solar thermal systems, and BTE Solar's blue coatings meet these requirements with ease. In Asia, the growing awareness of environmental issues and the need for energy-efficient solutions have led to an increasing adoption of BTE Solar's blue coatings. On the other hand, BTE Solar's black coatings are designed for cost-sensitive markets. These coatings are typically made from materials such as black chrome, black nickel, or black paint-based absorbers and are relatively simple and inexpensive to produce. While their performance may not be as high as that of the blue coatings, with absorption rates around 90% and thermal emittance in the range of 10 - 15%, they still offer a cost-effective solution for many applications. In Africa, South Asia, and parts of Latin America, where affordability is a key consideration, BTE Solar's black coatings have been widely adopted.
