비정질 박막 투과형 태양전지모듈의 온도특성에 따른 발전성능 평가 연구

This study evaluated the influence of temperature on the PV module surface on power output characteristics, especially for an amorphous transparent thin-film PV module which was applied to a full-scale mock-up model as building integrated photovoltaic system. The tested mock-up consisted of various slopes of PV module, facing to the south. The annual average temperature of the module installed with the slope of 30? revealed 43.1?C, resulting in 7?C higher than that measured in PV modules with the slope of 0?and 90? did. This 30? inclined PV module also showed the highest power output of 28.5W (measured at 2 PM) than other two modules having the power output of 20.4W and 14.9W in the same time for 0? and 90? in the slope, respectively. In case of the 30? inclined PV module, it exhibited very uniform distribution of power output generation even under the higher temperature on the module surface. Consequently, the surface temperature of the PV module analyzed in this study resulted in 0.22% reduction in power output in every 1?C increase of the module surface temperature.
