Solar energy conversion systems and daylighting schemes are important building energy strategies to produce clean energy, to reduce the peak electrical and cooling demands, to save the building electricity expenditures. A Dye Sensitized Solar Cell(DSC) is a next generation solar system. It is transparent, so various color rendering is possible. It has more economic merits more than previous silicon solar cell. recently, many studies on DSC have been carrrid out actively in America, Japan and Europe. Most DSC was produced in America, Japan and Europe. The efficiency of DSC was approximately 10%. A DSC is a building component generating electricity via PV modules and allowing daylight entering into the interior spaces to facilitate daylighting designs. The transmittance of DSC varies from 10% to 90%. As a optical transmittance of DSC was lower, Solar radiation absorption is higher and the glazing surface temperature of DSC rises and accordingly heating energy increases and cooling energy decreases. then DSC optical transmittance is very important parameter. But the comfort transmittance of office building through subjective evaluation is from 40% to 60%, and the proper transmittance is from 20% to 40% in glare evaluation. This paper studies the thermal and visual properties, energy performance and generation output power of DSC according to variable optical transmittance. |
