Parabolic Troughs without Solar Tracking System

Parabolic Troughs without Solar Tracking System Third International Conference on Applied Energy, Perugia, Italy (2011) Wattana Ratismith and Urith Archakositt Energy Research Institute, Chulalongkorn University, Bangkok 10330 Thailand Abstract In the general operation of a solar collector, the concentrating systems require sun tracking to maintain sunlight focusing at the collector. In addition, the solar collector cannot work effectively in diffused light conditions, therefore output from the system... Read More

Novel Parabolic Troughs without Solar Tracking System

Novel Parabolic Troughs without Solar Tracking System, Proc. Renewable Energy 2010 Pacifico Yokohama, Japan, (2010) Wattana Ratismith Energy Research Institute, Chulalongkorn University, Bangkok 10330 Thailand Abstract In the operation of the parabolic trough, the concentrating systems require sun tracking to maintain sunlight focus at the collector. In addition, the solar collector is unable to provide power in diffused light conditions, since the output from concentrating systems drops drastically... Read More

Hydrothermal synthesis of titanate nanoparticle/carbon nanotube hybridized material for dye sensitized solar cell application,

Abstract With the hydrothermal treatment, titanate nanostructure with distinctively different morphology and surface characteristics was successfully synthesized from commercial rutile titania powder dispersed in accommodating media which were deionized water or NaOH solution. Hybridized materials of titanate nanoparticles and carbon nanotubes (CNT) were also synthesized by the hydrothermal treatment process. Intrinsic interaction of titanate nanoparticles and CNTs could be confirmed by spectroscopic... Read More
