Description

串联光伏电池
技术领域
本发明涉及一种光伏电池领域。
特别地,本发明涉及光伏电池,包括两个光伏电池的垂直堆叠,也称为串联光伏电池。
背景技术
双结(串联)太阳能电池是光伏产业发展的下一阶段。其依赖于以晶体硅电池为基础的当前最先进的技术。因此,硅电池是串联电池的后电池,在太阳光谱的红外范围获得能量。同时,另一电池(即前电池)在可见光和紫外的补充范围获得能量并且放置在上方。现有技术中有多种结构,并且在前电池为III-V族的情况下进行说明。
对于所考虑的第一种结构,III-V电池在硅电池上的机械转移,并且接触点位于每个电池上。若中间接触点连通,则用于串联电池的最后接触点为位于前后的两个接触点,称为两引线配置。若两个电池之间电绝缘,则使用四根引线,称为四引线配置。对于另一种结构,两个电池之间的转移在这些电池的内层之间通过原子级紧密接触点直接进行,这允许在没有如第一种情况中添加的接触点的情况下使电流通过。第三种配置不使用机械转移技术,而是在硅结上直接外延生长III-V结,或者对于其它类型的前电池不采用此方法。在电气方面,两个电池直接与生长界面电接触。因此,得到了两引线电配置。所考虑的其它类型的前电池具有类似的现有技术,大多数是通过机械方式添加的两引线结构并且四引线电池。
当前的技术方案同样在于制作前单电池,特别是III-V电池,涵盖整个硅电池。就电气方面而言,该配置对应于两引线连接的电池,其中,两个结串联形成并通过隧道结构相互连接。在此配置中,硅电池应当是其中n区和p区位于硅片的两侧。这预先排除了对于具有交错布置的后接触点的电池的使用,但是这具有更好的效率。
专利申请WO 2017/093695描述了具有三个接触点的光伏电池。这样的电池允许例如将电子(n型载流子)从第一层转移到第二层,通过第一电极从第一层和第二层中收集电子,通过第二电极从第一层中收集空穴(p型载流子),以及通过第三电极从第二层中收集电子。该结构并不全部是单晶的,因为建议使用异质非晶硅结、氧化硅或非晶碳化硅合金。此外,该申请WO 2017/093695主张除外延之外的另一种制作技术。与具有两个接触点的光伏电池一样,具有三个接触点的光伏电池应当使电流在两个电池之间流动。两个电池之间并不是电绝缘的。
同样,专利申请WO 2009/047448以及同族申请涉及一种外延方法,该方法消除了不同单晶材料的层的晶胞参数差别。该申请主要提出微电子和光电子的应用,如LED,但是并未提出光伏电池的具体应用。
串联光伏电池允许使光伏的理论效率超过40%。这使得实际中的模块的效率可以超过30%。应当注意的是,所考虑的硅电池的结构在电池的两侧实现了接触点,这与典型的PERC、PERL等类型的电池的情况相同。然而,市场上、特别是Sunpower公司现有的性能最好的电池是具有交错布置的后接触点(interdigitated back contact,IBC)的电池。最近的趋势在于三洋公司引入的异质结结构,以及IBC概念被引入到电池中以得到高达26.6%的效率。因此,硅电池是当前市场上主要使用的电池。
发明内容
本发明的目的在于解决提供光伏电池的技术问题。
特别地,本发明的目的在于解决提供串联光伏电池、特别是在单晶硅下方使用光伏电池的技术问题。
更加特别地,本发明的目的在于解决提供串联光伏电池、特别是具有硅电池和III-V类型(硫族、特别是铜铟镓硒CIGS和镝化镉CdTe,或钙钛矿PbNH4I3类型)电池的垂直堆叠的技术问题。
本发明的目的在于解决提供具有晶体层的堆叠、特别是主要为单晶有源层的堆叠的串联光伏电池的技术问题。
本发明的目的在于解决提供具有上结的一体连接结构的串联光伏电池。
本发明的目的还在于提供具有后接触点的单晶硅光伏电池的技术问题。在光伏电池的墙面堆叠有具有整体连接的结的电池以及例如III-V类型(硫族(CIGS、CdTe)或钙钛矿)的结。
本发明的目的还在于解决提供四引线串联光伏电池的技术问题。
本发明的目的还在于解决本发明以产业方式、优选地为了限制产品成本提出的一个或多个技术问题。
