Description

一种双面玻璃BIPV光伏组件
技术领域
本发明涉及光伏组件领域，具体是一种双面玻璃BIPV光伏组件。
背景技术
太阳能电池是利用太阳光进行发电的半导体器件，太阳能电池芯片可以为非晶硅、非晶硅锗、微晶硅或纳米晶硅的单节或多节叠层硅基薄膜太阳能电池、CIGS 太阳能电池、铜铟锡太阳能电池、铜铟硫太阳能电池、单晶或准单晶硅太阳能电池、多晶硅太阳能电池、碲化镉太阳能电池、砷化镓太阳能电池、有机太阳能电池、染料敏化太阳能电池等。现有技术中采用的TPT材料，存在的缺点在于:TPT材料的使用寿命短，不透光，导致光伏组件的使用寿命短，满足不了客户对透光的需求。另外， EVA胶膜是目前主要用于封装太阳能电池的材料，但其存在一些不足，如易黄变老化，耐候性差、使用寿命短。
发明内容
本发明提供了一种具有清洁、高效、无污染、无噪音等特点，不排放任何有害物质的双面玻璃中空BIPV光伏组件。
本发明所述的一种双面玻璃BIPV光伏组件，包括硅晶片电池片，在硅晶片电池片的上、下表面封装PET/POE复合膜，在上表面PET/POE复合膜上方设有p-/n-型多晶硅吸收层，下表面PET/POE复合膜的下方设有n+/p+型a-Si：H发射层，在p-/n-型多晶硅吸收层的上方和n+/p+型a-Si：H发射层的下方均设有光伏玻璃，所述的光伏玻璃外表面设有防辐射金属薄膜。
进一步改进，所述的PET/POE复合膜由PET基材膜和改性POE胶膜贴压复合而成。
本发明的有益效果在于：
本发明的双面玻璃 BIPV 光伏组件的结构与普通太阳电池组件相比，最大的不同之处在于用玻璃代替了寿命短不透光的 TPT，极大地延长了光伏组件的寿命，并且能满足客户透光的要求；另外，BIPV 光伏组件具有清洁、高效、无污染、无噪音等特点，不排放任何有害物质，属绿色环保产品；采用PET/POE复合膜代替EVA胶膜封装，PET/POE复合膜的生产工艺简单，耐候性高、抗黄变性能增强、性能优良，成本低，可直接作为粘结背板和电池片的连接层，作为光伏组件封装材料有潜在的应用；玻璃外还设有防辐射金属膜，使得光伏组件对外辐射性小。
附图说明
图1为本发明结构示意图。
具体实施方式
下面结合附图对本发明做进一步说明。
本发明一种双面玻璃BIPV光伏组件，包括硅晶片电池片1，在硅晶片电池片的上、下表面封装PET/POE复合膜2，在上表面PET/POE复合膜上方设有p-/n-型多晶硅吸收层3，下表面PET/POE复合膜的下方设有n+/p+型a-Si：H发射层4，在p-/n-型多晶硅吸收层的上方和n+/p+型a-Si：H发射层的下方均设有光伏玻璃5，所述的光伏玻璃外表面设有防辐射金属薄膜6。
所述的PET/POE复合膜由PET基材膜和改性POE胶膜贴压复合而成，所述的PET基材膜1厚度为15 μm-30 μm；所述的改性POE胶膜2厚度为5 μm-10 μm。
本发明具体应用途径很多，以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以作出若干改进，这些改进也应视为本发明的保护范围。
