薄膜光伏技术在双层幕墙中的应用

Application of Photovoltaic Technology in Double-skin Curtain Wall

建筑节能既要主动利用太阳能,还要从结构上减少热损失,以获得最佳的经济效益。本文在双层幕墙和光伏发电系统工程实例的基础上,提出了一种新的光伏建筑一体化结构———光伏双层幕墙,并给出了相关设计经验。光伏双层幕墙采用薄膜光伏组件作为发电系统,双层幕墙作为主体结构,融合了热通道技术和光伏发电技术,具有明显的隔热、隔音、充分阳光、节能和装饰等功能,还可将太阳能转化成电能,与环境有着很好的相容性。

In order to obtain the best economic benefits on building energy-saving,not only the solar energy should be forwardly utilized,but also the heat loss through the building envelope should be reduced.In this paper,based on the project cases of double-skin curtain wall and photovoltaic engineering,the double-skin curtain wall integrated with photovoltaic（PV） technology was proposed and the relevant design experiences were introduced.In the photovoltaic double-skin curtain wall（PVDCW）,the thin-film solar cells was used as the PV components,and the double-skin curtain wall was taken as the main structure.In this curtain wall,the hot channel technology and PV technology were adopted.Therefore,the PVDCW had several advantages,such as heat insulation,sound insulation,plenty sunlight,energy-saving and perfect decoration,etc.Furthermore,it could translate the solar energy into electricity and had good compatibility to the environment.
