为了研究柔性非晶硅薄膜光伏电池-乙烯四氟乙烯共聚物(简称PV-ETFE)气枕结构的温度特征,设计了由三层ETFE气枕与集成于其中层膜上表面PV组成的气枕1及由双层ETFE气枕与集成于其上层膜上表面PV组成的气枕2,实测了两种气枕的PV和ETFE薄膜的夏季温度数据.通过分析得到:两种气枕的PV和ETFE薄膜温度差分别为35.4℃和26.2℃;气枕1和气枕2ETFE薄膜受气枕内空气温度和气枕外空气流动影响明显;PV温度受阴影及太阳光入射角影响.
To investigate temperature characteristics of the ethylene-tetra-fluoro-ethylene(ETFE)cushion integrated flexible amorphous silicon photovoltaic panels(PV-ETFE for short),two types of PV-ETFE cushions were designed.Cushion 1was a three-layer ETFE cushion integrated PV on surface of its middle layer and cushion 2was a double-layer ETFE cushion integrated PV on surface of its top layer.Then,temperature of the two PV-ETFE cushions in summer was field-measured.The results show that temperature differences between the two PV-ETFE cushions were 35.4℃for PV and26.2℃for ETFE foils,the major influencing factors for ETFE foil of cushion 1,ETFE foil of cushion2 and PV are the air temperature in cushion 1,air flow outside the cushion 2,and shade and angle of incidence of the solar irradiance,respectively.
