A key issue in solar energy research and development is correlating the performance of solar energy devices with the methods and materials used to produce them. The optical properties of these materials are fundamental to device performance. The relationship among materials growth and processing, the resulting electro-optical properties, and device performance can be extremely complex and difficult to determine without direct measurement. Surface Optics’ reflectometers are used in solar collector deposition and cleaning, solar selective coating development, concentrated solar power tower design, thermal energy storage media development, and photovoltaic semiconductor material development.

Solar Collector Deposition and Cleaning

For those managing solar energy facilities, ensuring optimal performance and longevity of solar collectors is crucial for maximizing efficiency and reducing costs. Surface Optics’ reflectometers are essential tools, providing precise measurements of reflectance and cleanliness. This enables facility managers to accurately assess and maintain solar collectors, ensuring peak efficiency. By regularly monitoring and cleaning solar collectors, industry professionals can extend the lifespan of their equipment and maintain its effectiveness, contributing to a more sustainable energy future.
