Kurzfassung
We demonstrated the broadband and near-perfect solar absorption of carbon nanotube (CNT) based black coating prepared by low-cost wet-deposition method on reflective metal surface for mid-temperature non-evacuated Concentrated Solar Power (CSP) application. The controlled density of CNTs in the ceramic matrix exhibits absorptance of 0.985 in the entire solar spectrum and emittance of 0.90 in IR region. The coating exhibits durable superhydrophilic property with 0° contact angle after plasma treatment without affecting the solar absorptance and excellent coating adhesion measured at 85-95% of the area. The efficiency of the coating was evaluated by analytical models and it reveals that the CNT-based coating shows higher efficiency at low temperature and at high concentration ratio than that of selective coatings.
