Carbon Nanotube for Solar Energy Applications: A Review
Keywords:solar collector, carbon nanotube, thermal conductivity, nanofluid
This paper reports the recent researches of carbon nanotube application in solar collectors. The efficiency of different stationary solar collectors (Flat plate collector FPC, Evacuated tube solar collector ETSC and Direct absorber solar collector DASC) was found to improve with the use of single wall carbon nanotube (SWCNT) and multiwall carbon nanotube (MWCNT) respectively. From literatures many comparisons were reported with other nanoparticles, it has shown that carbon nanotube display higher thermal conductivity compared to other solid nanoparticles. Effect of thermal conductivity, stability and production cost of SWCNT and MWCNT was thoroughly reviewed and investigated for application in stationary solar collectors.
