摘要
采用新型碲化镉BIPV光伏玻璃为试验对象,研究了其在 100、200、300、400、500 和 600 μmol·m-2·s-16 种光强下的LED红光、红蓝光(4∶1)和典型晴朗天气太阳光下植物生理有效辐射光质的透光率.结果表明,6 种光强下LED红光透光率分别为 38.39%、42.52%、45.43%、38.94%、39.57%和 48.80%,红蓝光透光率分别为 49.11%、44.09%、42.98%、48.95%、49.64%和48.54%.太阳光下红光、蓝光、绿光和紫外光透过率分别为 39.97%、39.49%、40.75%和39.78%,与透光率设计值40%十分接近.400～700 nm可见光透过率达到了 42%.因此,采用该新型碲化镉BIPV光伏玻璃作为日光温室和太阳光植物工厂覆盖材料,取代传统材料具有一定的可行性.
Abstract
A new type of cadmium telluride BIPV glass was used as the experimental object,and the light transmittance of LED monochromatic red light,red-blue mixed light(4∶1)and sunlight in typical sunny days were studied under six light intensities of 100,200,300,400,500 and 600 μmol-2·s-1.The results show that the red light transmittance of LED is 38.39%,42.52%,45.43%,38.94%,39.57%and 48.80%respectively.The light transmittance of red and blue light is 49.11%,44.09%,42.98%,48.95%,49.64%and 48.54%respectively.The transmittance of red light,blue light,green light and ultraviolet light in sunlight is 39.97%,39.49%,40.75%and 39.78%respectively,which is very close to the designed transmittance of 40%.The transmittance of visible light(400-700 nm)was up to 42%.Therefore,it is feasible to use this new type of cadmium telluride BIPV glass as a covering material for greenhouses and solar plants factories to replace traditional materials.
