High performance Thermal Coating Comprising (CuO:NiO) Nanocomposite/C Spectrally Selective to Absorb Solar Energy

Application of Solar Thermal Collectors to Improve the Energy Performance of the Fresh Air HVAC Systems

 In the preset study, the performance of a solar assisted heating, ventilation and air conditioning (HVAC) system in an operating theater building was studied. The yearly performances of the existing HVAC system and the system with the added solar collectors were simulated in terms of energy consumption and provided air conditions using a transient system simulation software (TRNSYS). In t...

Progress in Development of High-temperature Solar-selective Coating

Improving the properties of the selective coating on the receiver represents one of the best opportunities for improving the efficiency of parabolic trough collectors and reducing the cost of solar electricity. Additionally, increasing the operating temperature above the current operating limits of 400oC can improve power cycle efficiency and reduce the cost of thermal energy storage resulting ...

High-performance absorbers for solar thermal applications

Energy has emerged as one of the most significant and universal concerns society will face in this century. Currently, the world relies on fossil fuels to produce 86% of its energy. However, the combustion of fossil fuels generates greenhouse gases, a major factor responsible for global warming. Because concentrated solar thermal (CST) systems offer a pathway to a cost-competitive alternative t...

Highly Efficient Selective Metamaterial Absorber for High-Temperature Solar Thermal Energy Harvesting

In this work, a selective solar absorber made of nanostructured titanium gratings deposited on an ultrathin MgF2 spacer and a tungsten ground film is proposed and experimentally demonstrated. Normal absorptance of the fabricated solar absorber is characterized to be higher than 0.9 in the UV, visible and, near infrared (IR) regime, while the mid-IR emittance is around 0.2. The high broadband ab...
