　　光伏玻璃产品介绍光伏玻璃是一种通过层压入太阳电池，能够利用太阳辐射发电，并具有相关电流引出装置以及电缆的特种玻璃。它有着美观、透光可控、节能发电且它不需燃料，不产生废气，无余热，无废渣，无噪音污染的优点，应用非常广泛，如：太阳能智能窗，太阳能凉亭和光伏玻璃建筑顶棚，以及光伏玻璃幕墙等等。光伏玻璃可分为晶体硅光伏玻璃和薄膜光伏玻璃两大类，其中幕墙最常用的是晶体硅类，他又分单晶硅和多晶硅两类。下面介绍的一种光伏玻璃是由玻璃－PVB（EVA）胶膜－太阳电池－PVB（EVA）胶膜－玻璃共5层组成(见下图)，类似于建筑上常用的夹胶玻璃，具有很好的安全性。可以通过控制双面玻璃之间的电池间隙和边缘空隙，来制成5%～80%透光率的光伏玻璃。中空光伏玻璃是将中空玻璃的外层玻璃替换成双玻夹胶光伏组件，在生产工艺上比双玻夹胶光伏组件多一些合成中空的步骤。并无本质区别。由于晶体硅光伏组件在高温时的发电效率会下降一些，因此中空光伏组玻璃一般在非高温地区使用较多。薄膜光伏玻璃的特点是重量轻、厚度薄、可弯曲、易携带，弱光性好，在早晚光线弱的情况下，发电效果优于单晶硅电池，但并没有传统硅晶电池转化效率高。

Photovoltaic glass is a kind of special glass which can generate electricity by solar radiation through laminated solar cells and has related current elicitor and cable. It has the advantages of being beautiful, transparent and controllable, energy saving power generation, no fuel, no waste gas, no waste heat, no waste, no noise pollution, and it has a wide range of applications, such as: solar smart windows, solar pavilions and photovoltaic glass roof, And photovoltaic glass curtain wall and so on. Photovoltaic glass can be divided into two categories: crystalline silicon photovoltaic glass and thin film photovoltaic glass. The photovoltaic glass described below is composed of five layers of glass-PVB EVA) film and solar cell (see figure below, similar to the commonly used glass-clamped glass in architecture, with good safety. The photovoltaic glass with 80% transmittance can be made by controlling the cell gap and edge gap between the two sides of glass. The hollow photovoltaic glass is to replace the outer glass of the hollow glass with the double glass sandwich photovoltaic module, which is more hollow than the double glass sandwich photovoltaic module in the production process. There is no essential difference. Because the efficiency of the crystal silicon photovoltaic module will decrease at high temperature, the hollow photovoltaic glass is usually used in the non-high temperature area. Thin film photovoltaic glass is characterized by light weight, thin thickness, bending, easy to carry and good weak light. In the case of weak light in the morning and evening, the power generation effect is better than that of single crystal silicon cell, but the conversion efficiency is not higher than that of traditional silicon crystal cell.
