英文要約Title: New Energy Venture Business Technology Innovation Program / New Energy Venture Business Technology Innovation Program (Wind power generation and other untapped energies) / Research and Development of efficient solar collector using carbon nanotubes (FY2014 - FY2016) FY2015 Annual report

We changed molarity density of titanium oxide materials (TiO2) and spraying method for a strong rise of a solar collector. As a result, coming off from surface of collector passed away and went up the strength. It is optimized now. The absorption of sunlight is still maintain about 99% (wavelength: 250-2500nm). Crosscut method test is not acted. 'Development of base layer of solar collector and strong rise of base layer'. We succeeded in making synthetic base material with TiO2. Reacting solvent and ligand of TiO2 were changed and it is optimized. The big crack when using competitor's products was improved. Adhesion to a substrate was improved. A constitution adjustment of silica material is performed and sprayed on the heated substrate. We succeeded to apply to the whole solar collector equally thin. We did not use CVD method because we succeeded in this way. The 20cm pipe heating machine is delivered and we started spray to the heated pipe. Discharge quantity and spraying time is optimized. We succeeded to spray on 20cm heated pipe and started to create best condition of heated 1m pipe. Pore structure was changed with change in the law material and change in spraying method. The light absorption is improved. Principle explication by new method is being into effect. We heard in detail about required specifications, diameter of the pipe, the length and cost for performance evaluation from user.
