双面玻璃晶体硅太阳能组件

双面玻璃晶体硅太阳能组件

双面玻璃晶体硅太阳能电池组件有着美观、透光的优点，应用非常广泛，如：太阳能智能窗、太阳能凉亭和光伏建筑顶棚，以及

光伏玻璃幕墙等等。随着国内外光伏建筑一体化的推广，其商业市场将进一步扩大。

双面玻璃晶体硅太阳能电池组件的结构

双面玻璃太阳电池组件的结构有多种，本文主要讨论的是层压封装的双面玻璃晶体硅太阳电池组件（简称双面玻璃组件）。图1是双面玻璃太阳电池组件结构。这种组件由玻璃-EVA胶膜-太阳电池- EVA胶膜-玻璃共5层组成。与普通太阳电池组件结构相比，双面玻璃组件利用背板玻璃代替TPE（或TPT）。TPE为柔性材料，玻璃是硬度高的刚性材料，双面玻璃层压封装过程中由于两层刚性玻璃的挤压，很容易出现气泡、移位、太阳电池裂片、玻璃碎裂现象。

Packaging technology of double-glazed crystalline silicon solar components

Double-glazed crystalline silicon solar cellhas the advantages of aesthetics and good transmittance. It has a wide application range, such as solar intelligent window, solar pavilion, PV building ceiling, PV glass curtain wall, etc. With the promotion of domestic and international BIPV, its commercial market will expanded further.

Structure of double-glazed crystalline silicon solar cell

The structure of double-glazed solar cell is various, what we’ll discuss here is the double-glazed crystalline silicon solar cell with laminated packaging (Double-glazed component for short). The structure of double-glazed solar cell refers to Figure 1. This kind of component consists of five layers of glass-EVA film - solar cell - EVA film - glass. Compared with the structure of ordinary solar cell, double-glazed component uses back glass instead of TPE (or TPT). TPE is flexible material and glass is rigid material, which is easy to cause bubbles, shift, solar cell fragmentations and glass fragmentations due to the extrusion of two layers of rigid glass in the process of laminated packaging.
