تسلبط الضوء على مواد انتقاء حزم الطيف الشمسي وانواعها وتطبيقاتها
Since solar–thermal collectors are considered to be the most direct way of converting solar
energy into usable forms, in the last few years growing attention has been paid to the
development of transition metal nitride and metal oxynitride based thin film selective surfaces for solar–thermal collectors, in order to harvest more solar energy. A solar–thermal energy system, generally, shows very high solar absorption of incident solar radiation from the solar–thermal collectors in the visible range (0.3 to 2.5 μm) and extremely low thermal losses through emission (or high reflection) in the infrared region (2.5 μm). The efficiency of a solar–thermal energy conversion system can be improved by the use of solar selective surfaces consisting of novel metallic nanoparticles embedded in metal nitride/oxynitride systems
