Description

光电转换模组及光电转换系统 技术领域
本发明属于光伏领域,具体地涉及一种光电转换模组及光电转换系统。
背景技术
众所周知,太阳光无处不在,鉴于太阳光对应的光能取之不竭,用之不尽,因此,利用太阳光实现能量利用的项目越来越多,截至目前,利用太阳光发电在现有电力供应中扮演着越来越重要的角色。
请参阅图1,是利用太阳光实现光能至电能的转换系统框架示意图。在利用太阳光实现光能至电能的转换系统中,主要包括光能提供元件61、光电转换器62及电能输出装置63。
所述光能提供元件61,即太阳,或经过光学处理的阳光,或二次辐射源辐射光,并将光能传递至所述光电转换器62。所述光电转换器62接收光能并将光能转换为电能,形成电压。所述电能输出装置63将电压施加至外接电路上,形成电流,由此实现光能转换为电能,最终输出的过程,亦即光能至电能的转换过程。
由此可见,在利用太阳光实现光能至电能的转换系统中,所述光电转换器62(也叫太阳能电池组件或者光伏组件)是整个发电系统中的核心部分,其作用是将太阳能转化为电能,一般接入电网统一调配使用,或送往蓄电池中存储起来,或直接推动负载工作。
如图2所示,所谓光伏组件(太阳能电池组件)是由太阳能电池片或由激光切割机或钢线切割机切割开的不同规格的太阳能电池组合在一起构成。由于单片太阳能电池片的电流和电压都很小,于是业界把上述多个太阳能电池片先串联获得高电压,再并联获得高电流后然后输出,其中所述单片太阳能电池片的规格包括:125*125mm、156*156mm、124*124mm等。将多个单片太阳能电池片封装在一个 钢化玻璃的基板上,四周安装不锈钢、铝或其他非金属边框形成整体称为组件,也就是光伏组件或太阳电池组件。
然而,单一光电转换单元只能产生大约0.5伏的工作电压,远低于实际使用所需电压。为了满足实际应用的需要,需要把多个光电转换单元连接成光电转换器,或者光伏组件。请再次参阅图2,所述光电转换器500包含一定数量的光电转换单元501,例如是二十四片,上述光电转换单元501通过导线对应电连接,如此形成大约能产生12伏工作电压的光电转换器500,或者光伏组件500。
现有技术的光电转换器中,光电转换单元的电连接方式主要以串联为主。其中,公开号为CN103094385A的发明专利公开了一种光电转换器700,如图3所示,光电转换器1中光电转换单元710以串联方式电连接。公开号为CN104617169A的发明专利公开了一种光电转换器,如图4所示,在光电转换器800中,光电转换单元810均以串联方式构成所述光电转换器800。在上述两种光电转换器中,串联设置的光电转换单元710、810可以获得高输出电压从而减小电能损耗,但是其缺陷在于串联设置的光电转换器700、800无法充分利用非均匀光照条件,即其总的输出电流受限于被最弱光照的光伏电池产生的最小电流。为了避免其总的输出电流受限于被最弱光照的光电转换单元产生的最小电流,现有技术往往采用旁路二极管的方案绕过这部分被最弱光照的光电转换器,因此没有充分利用阳光资源和已投入使用的设备。
针对无法充分利用非均匀光照的缺陷,业界为了进一步地利用非均匀光照,现有技术公开号为CN101978510B的中国专利和专利号为US8748727的美国专利公开了一种由光电转换单元并联连接构成的光电转换器,如图5所示。该光电转换器900中,光电转换单元904彼此并联连接形成多个行906,然后多个行906之间串联连接。该光电转换器900中并联连接的光电转换单元904使得该光电转换器900可以降低对非均匀光照的敏感性,提高其在常见非均匀光照条件下的输出电能;但是其缺点在于并联连接的光电转换单元904具有较低的 输出电压和较大的输出电流,这会增加该光电转换器900输出电能的损耗。而且较大的输出电流需要使用较粗的导线以传导电流,这又会增加该光电转换器900的成本。
但是,对于在特定情况下的非均匀光照条件,例如沿第一维方向光能强度均匀,沿垂直于所述第一维方向的第二维方向光能强度非均匀的光照,目前业界尚未发现充分利用该特定情况下的非均匀光照进行光伏发电的研究。
因此,有必要提供一种可以造成该特定情况的非均匀光的光源,以及可以充分利用该特定情况下的非均匀光照的光电转换模组及光电转换系统。

具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明的一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
请同时参阅图6及图7,其中图6是本发明实施例提供的光电转换系统的结构示意图,图7是图6所示光电转换系统中光能输出装置和光电转换阵列之间的光束传输示意图。所述光电转换系统100包括光能输出装置1、光电转换阵列3和电能输送装置5。所述光能输出装置1输出光束至所述光电转换阵列3表面。所述光电转换阵列3将光能转变为电能。所述电能输送装置5输送所产生的电能。
所述光能输出装置1包括光源11及导光模组13。所述光源11产生的光束包括两部分,其中一部分光束直接传输至所述光电转换阵列3的表面,另一部分则经所述导光模组13导引后传输至所述光电转换阵列3表面。所述导光模组13配合所述光电转换阵列3传输来自所述光源11的光束至所述光电转换阵列3的入光面,并最终在所述光电转换阵列3表面形成沿设定方向光强分布均匀的光照结构。
所述光源11是太阳光或者人工光源。在本发明中,所述光源11是广义的光源,凡是旨在为光伏发电提供光能的任何光辐射源均在本发明的创作宗旨内,主要是指太阳以及以太阳为源头的二次辐射源。在本实施例中,所述光源11可以为固定光源,也可以为移动光源。
所述导光模组13引导所述光源11发出的部分光束至所述光电转换阵列3表面。对应于所述光源11,当所述光源11为固定光源时,所述导光模组13与所述光源11之间的相对位置固定,其直接导引部分光束至所述光电转换阵列3表面。当所述光源11为移动光源时,所述导光模组13与所述光源11之间的相对位置是不固定的,即所述导光模组13与所述光源11之间的相对位置随着所述光源11的移动而变化,同时保证所述光源11与所述导光模组13之间的相对位置在 设定范围,使得更多的光束经由所述导光模组13导引至所述光电转换阵列3表面。在本实施例中,随着所述光源11的移动,所述导光模组13与所述光源11之间的相对位置是不固定的。
具体而言,以所述光源11为太阳作为例子,太阳在一天不同时刻相对于所述导光模组13的位置是不断变化的,而且太阳在地球上某点的入射光束的角度在不同季节也不相同。如此,所述导光模组13可以追踪一天中不同时刻太阳的位置变化以保证所述导光模组13始终以合适的方向和角度最大限度接收太阳光。另一方面,太阳在不同季节,其与地球的夹角有所不同,如此还可以根据不同季节太阳入射光束的角度的改变而调节所述导光模组13面向太阳的角度。
在本实施例中,以所述导光模组13不需要追踪一天中不同时刻太阳的位置变化为例,其仅仅按照不同季节太阳入射光束的角度的改变来调节所述导光模组13。也就是说,所述导光模组13不会根据太阳在一天中不同时刻位置的变化而调节其面向太阳的角度,而是在每一个季节内按照该季节的太阳入射光束的角度调节一次所述导光模组13面向太阳的角度。优选地,所述导光模组13可以按照不同季节太阳入射光束的角度的改变手动调节所述导光模组13面向太阳的角度。
更进一步地,所述导光模组13还可以不追踪太阳在一年中位置的变化。也就是说,尽管太阳的位置发生变化,所述导光模组13始终以固定的位置接收太阳光,不需要根据太阳位置的变化而调节所述导光模组13面向太阳的角度。
其中,所述导光模组13还可以包括多个子导光模组,所述多个子导光模组配合构成所述导光模组13。在本发明中,所述导光模组13可以是反射板实现光束反射传输,也可以是折射板,通过折射改变光束传输方向以实现聚光。
取所述光电转换阵列3的功能区表面为入光面300,以该入光面300所在平面为参考平面,于该平面内,界定相互垂直的第一维方向和第二维方向。设定沿X轴平行方向为所述第一维方向,沿垂直于X 轴的Y轴平行方向为所述第二维方向。在本发明提供的光能输出装置1中,所述光源11配合所述导光模组13传输光束至所述光电转换阵列3的入光面300,在所述入光面形成沿所述第一维方向光强分布均匀,沿垂直于所述第一维方向的第二维方向光强呈非均匀分布的光照。
其中,本发明实施例中,所述光强分布均匀的光照是指在指定区域内,光照的最大光强和最小光强的差值小于10W/m2。所述差值的来源是不均匀的灰尘分布,器件制造的缺陷等等。例如,请参阅图8,在沿平行于所述第一维方向上,所述光照的光强在小范围内波动,且光照的最大光强与最小光强之间的差值小于等于10W/m2。所述光强分布非均匀的光照是指在指定区域内,光照的最大光强和最小光强的差值一般大于10W/m2。所述差值的来源主要是由于光学设计而产生光强差异。例如,请参阅图9,在沿平行于所述第二维方向上,所述光照的光强在较大范围内波动,且光照的最大光强值与最小光强值之间的差值大于10W/m2
其中,沿所述第一维方向光强分布均匀,沿垂直于所述第一维方向的第二维方向呈非均匀分布的光照可以在所述入光面形成n个平行所述第一维方向的光照带,分别记为:第一光照带、第二光照带、......、第n光照带,其中n为大于等于1的自然数。例如,如图10所示,在所述n个光照带之间,所述光照的光强非均匀分布,且呈阶梯分布;每个所述光照带内的光强趋于基本均匀分布。
再请结合参阅图7及图11,其中图11是图7所示光电转换阵列中光电转换器的平面结构示意图。所述光电转换阵列3包括多个阵列设置的光电转换器35及多个输出端30。所述光电转换器35及多个输出端30分别对应电连接形成多个分别独立输出电能的光电转换单元带组。每一光电转换器35包括基板350、多个光电转换单元带351及内部输出端子352。所述多个光电转换单元带351平行间隔设于所述基板350表面,所述基板350用于支撑所述多个光电转换单元带351。所述内部输出端子352分别对应串接所述多个光电转换单元带 351,并对应分别独立输出每一光电转换单元带351利用光能产生的电能。对应沿同一方向延伸的不同基板350上的多个光电转换单元带351对应串接形成一光电转换单元带组。
所述基板350为电绝缘材料,其可以为所述光电转换单元带351提供散热途径。例如,所述基板350可以是由导热的电绝缘材料制备而成,传统的基板是钢化玻璃,位于正面;所述基板350当然也可以位于背面,可以是钢化玻璃,也可以是其它合适的电绝缘材料。所述光电转换单元带351工作过程中产生的热量可以传导至所述基板350,并经由所述基板350散发于周围环境中。可选择地,所述基板350还可以包括贯穿所述基板350的散热孔,以加强所述基板350的散热性能。
所述多个光电转换单元带351相互平行间隔,且相邻所述光电转换单元带351之间彼此电位隔离设置。其中,沿所述第一维方向,所述多个光电转换单元带351分别与所述第一维方向平行设置;沿所述第二维方向,所述多个光电转换单元带351之间相互间隔,并彼此电位隔离设置,所述间隔尺寸介于0.1毫米至3毫米之间。
所述多个内部输出端子352是相互独立,且电位隔离的输出端,其分别独立地输出相对应的所述光电转换单元带351产生的电能,其中每一光电转换单元带351对应连接一内部输出端子352。
请参阅图12,是图11所示光电转换单元带的结构示意图。所述光电转换单元带351包括多个光电转换单元3510。所述多个光电转换单元3510线性串设于所述内部输出端子352之间,形成具有独立供电功能的光电转换单元带351。所述多个光电转换单元3510依次串联设于所述内部输出端子352之间,使得所述多个光电转换单元3510产生的电能汇集于所述内部输出端子352。而且,所述内部输出

单元带351利用光能产生的电能。其中,所述光电转换单元3510是光伏电池,其可以为单晶太阳能电池、多晶太阳能电池、非晶硅太阳能电池或薄膜电池,或其他光伏电池,本发明对此不作限定。
在每一所述光电转换单元带351内,相邻所述光电转换单元3510之间通过导电线路串接设置,且组成所述光电转换单元带351的每一光电转换单元3510尺寸基本相同。其中,在每一所述光电转换单元带351内,依次串设于所述内部输出端子352之间的多个光电转换单元3510呈线性阵列设置。
在本实施例中,每一所述光电转换单元带351包括相同数目的所述光电转换单元3510。当然,在其他可替代实施例中,组成所述光电转换单元带351的光电转换单元3510的数目也可以不相同,对应尺寸亦可以相异,本发明对此不作限定。
在每一所述光电转换单元带351内,依次串设于所述内部输出端子352之间的多个光电转换单元3510呈直线排列,且平行于所述第一维方向。其中,所述输出端30分别位于所述光电转换器35的相异侧。
在图12所述光电转换单元带351中,设于所述内部输出端子352之向的多个光电转换单元3510不限于依次串联设置,作为上述实施方式的进一步变形,其还可以是并联设置,以及串联并联混合设置, 例中,所述导光模组13为反射板,所述反射板接收来自所述光源11的光束,并反射所述光束朝所述光电转换阵列3的入光面300侧传输。
其中,所述光电转换阵列3的光电转换器35入光面300可以直接接收来自所述光源提供的光束,也可以接收经过所述导光模组13反射的光束。因此,根据所述光电转换阵列3的入光面300的光束分布,可以分为如下几种情况。
请参阅图16a,所述光电转换阵列3的光电转换器35入光面300整体仅接收直接来自所述光源提供的光束。由于所述光源11提供的光束全面覆盖所述入光面300,因此,所述入光面300形成各个方向光强分布均匀的光照。
请参阅图16b,所述光电转换器35的入光面300不仅接收直接来自所述光源提供的光束,还接收经过所述导光模组13反射的光束,并且上述两种光束在所述入光面300部分重叠。根据所述入光面300接收光束的重叠情况,可以将所述入光面300形成两个沿所述第一维方向平行的区域:
区域一,仅接收直接来自所述光源提供的光束,因此所述区域一内的入光面300的光照光强分布均匀;
区域二,同时接收直接来自所述光源11提供的光束和经过所述导光模组13反射的光束,因此所述区域二是上述两种光束的重叠区域,在所述区域二内的入光面300的光照光强分布均匀。
其中,由于所述区域一是所述入光面300仅接收直接来自所述光源11提供的光束的区域,所述区域二是所述入光面300同时接收上述两种光束的区域,因此,所述区域二的光照光强必然大于所述区域一的光照光强。也就是说,沿平行于所述第一维方向,所述区域一的光照光强和所述区域二的光照光强分别均匀分布;沿平行于所述第二维方向,所述区域二的光照光强大于述区域一的光照光强。即在所述光电转换器35的入光面131形成沿所述第一维方向光强均匀分布,而垂直于所述第一维方向的第二维方向呈非均匀分布的光照。
请参阅图16c,所述入光面300不仅接收直接来自所述光源11 提供的光束,还接收经过所述导光模组13反射的光束,而且上述两种光束全面重叠并覆盖所述入光面300。如此,在所述入光面300各个方向形成光强分布均匀的光照。
请参阅图16d,所述导光模组13遮挡了部分所述光源11发出的光束。由于所述光源11发出的光束与所述导光模组13之间角度使得所述导光模组13没有接收到来自所述光源11的光束,反而遮挡了部分所述光束导致所述入光面300只有部分区域接收到所述光束,而所述入光面300的其余区域则没有被所述光束覆盖,由此在所述入光面300形成遮光区和覆光区。所述遮光区和所述覆光区相邻且沿所述第一维方向相互平行。在所述遮光区内,所述光照的直射光强基本为零;在所述覆光区内,所述光照的光强均匀分布。如此,则沿所述第一维方向,所述入光面300的覆光区形成光强均匀的光照;而在垂直于所述第一维方向的第二维方向,所述入光面300的遮光区和覆光区配合形成光强不均匀的光照。
实施例二
请参阅图17,与实施例一提供的光能输出装置11基本相同,唯不同在于:所述光电转换器35和所述导光模组13是由多个平行于所述第一维方向的条状的板体矩阵组合而成。其中,所述光电转换器35阵列设置形成平行间隔设置的多个光电转换单元带组(未标示)。相对应地,所述导光模组13也可以包括多个平行于第一维方向且相邻设置的子反射板130,所述多个子反射板130配合矩阵形成所述导光模组13。其中,所述光电转换单元带组的排列方向与所述导光模组13内部的子反射板130的排列方向相同,即沿平行于所述第一维方向阵列排列。
当所述光源11发出的光束照射过来后,所述子反射板130引导所述光束至所述光电转换单元带组的入光面300形成平行于所述第一维方向的每状光照。所述光电转换单元带组的入光面300整体上可以形成沿第一维方向光强均匀,垂直于第一维方向的第二维方向的光 强不均匀的光照。

束。上述光束在所述入光面300的分布情况与所述实施例一类似,在此不做赘述。
实施例四
请参阅图19,是图7所示光能输出装置的实施例四的侧面示意 例中,所述导光模组13为反射板,所述反射板接收来自所述光源11的光束,并反射所述光束朝所述光电转换阵列3的入光面300侧传输。
其中,所述光电转换阵列3的光电转换器35入光面300可以直接接收来自所述光源提供的光束,也可以接收经过所述导光模组13反射的光束。因此,根据所述光电转换阵列3的入光面300的光束分布,可以分为如下几种情况。
请参阅图16a,所述光电转换阵列3的光电转换器35入光面300整体仅接收直接来自所述光源提供的光束。由于所述光源11提供的光束全面覆盖所述入光面300,因此,所述入光面300形成各个方向光强分布均匀的光照。
请参阅图16b,所述光电转换器35的入光面300不仅接收直接来自所述光源提供的光束,还接收经过所述导光模组13反射的光束,并且上述两种光束在所述入光面300部分重叠。根据所述入光面300接收光束的重叠情况,可以将所述入光面300形成两个沿所述第一维方向平行的区域:
区域一,仅接收直接来自所述光源提供的光束,因此所述区域一内的入光面300的光照光强分布均匀;
区域二,同时接收直接来自所述光源11提供的光束和经过所述导光模组13反射的光束,因此所述区域二是上述两种光束的重叠区域,在所述区域二内的入光面300的光照光强分布均匀。
其中,由于所述区域一是所述入光面300仅接收直接来自所述光源11提供的光束的区域,所述区域二是所述入光面300同时接收上述两种光束的区域,因此,所述区域二的光照光强必然大于所述区域一的光照光强。也就是说,沿平行于所述第一维方向,所述区域一的光照光强和所述区域二的光照光强分别均匀分布;沿平行于所述第二维方向,所述区域二的光照光强大于述区域一的光照光强。即在所述光电转换器35的入光面131形成沿所述第一维方向光强均匀分布,而垂直于所述第一维方向的第二维方向呈非均匀分布的光照。
请参阅图16c,所述入光面300不仅接收直接来自所述光源11 提供的光束,还接收经过所述导光模组13反射的光束,而且上述两种光束全面重叠并覆盖所述入光面300。如此,在所述入光面300各个方向形成光强分布均匀的光照。
请参阅图16d,所述导光模组13遮挡了部分所述光源11发出的光束。由于所述光源11发出的光束与所述导光模组13之间角度使得所述导光模组13没有接收到来自所述光源11的光束,反而遮挡了部分所述光束导致所述入光面300只有部分区域接收到所述光束,而所述入光面300的其余区域则没有被所述光束覆盖,由此在所述入光面300形成遮光区和覆光区。所述遮光区和所述覆光区相邻且沿所述第一维方向相互平行。在所述遮光区内,所述光照的直射光强基本为零;在所述覆光区内,所述光照的光强均匀分布。如此,则沿所述第一维方向,所述入光面300的覆光区形成光强均匀的光照;而在垂直于所述第一维方向的第二维方向,所述入光面300的遮光区和覆光区配合形成光强不均匀的光照。
实施例二
请参阅图17,与实施例一提供的光能输出装置11基本相同,唯不同在于:所述光电转换器35和所述导光模组13是由多个平行于所述第一维方向的条状的板体矩阵组合而成。其中,所述光电转换器35阵列设置形成平行间隔设置的多个光电转换单元带组(未标示)。相对应地,所述导光模组13也可以包括多个平行于第一维方向且相邻设置的子反射板130,所述多个子反射板130配合矩阵形成所述导光模组13。其中,所述光电转换单元带组的排列方向与所述导光模组13内部的子反射板130的排列方向相同,即沿平行于所述第一维方向阵列排列。
当所述光源11发出的光束照射过来后,所述子反射板130引导所述光束至所述光电转换单元带组的入光面300形成平行于所述第一维方向的条状光照。所述光电转换单元带组的入光面300整体上可以形成沿第一维方向光强均匀,垂直于第一维方向的第二维方向的光强不均匀的光照。
实施例三
请同时参阅图18,本发明实施例提供的导光模组13包括第一反射板131和第二反射板135。所述第一反射板131和所述第二反射板135分别设置于所述光电转换器35入光面300的相对两侧。所述第一反射板131所述第二反射板135均可以接收来自所述光源的光束,并反射光束朝所述光电转换器35的入光面300侧传输。
所述入光面300可以接收直接来自所述光源11提供的光束,也可以接收经过所述第一反射板131和所述第二反射板135反射的光束。上述光束在所述入光面300的分布情况与所述实施例一类似,在此不做赘述。
实施例四
请参阅图19,是图7所示光能输出装置的实施例四的侧面示意图。所述导光模组13为透光板,所述透光板接收来自所述光源的光束,并折射所述光束朝所述光电转换器35的入光面侧传输。所述透光板可以为包括菲涅尔透镜或普通透光镜的透光板,主要是特定设计的非成像折射板。
优选地,所述导光模组13可以为聚光透镜,即为具有聚光功能的透光板。所述聚光透镜接收来自所述光源的光束,并汇聚所述光束传输至所述光电转换器35的入光面300。而且,根据所述导光模组13所汇聚光线在所述入光面300的重叠程度,在所述入光面300可以形成沿所述第一维方向光能强度分布均匀,同时,沿垂直于所述第一维方向的第二维方向呈非均匀分布的光照。
可替代地,所述导光模组13还可以是具有抛物线孤面的反射镜,所述孤面反射来自所述光源的光束至所述承载体的入光面侧。其反射原理与实施例二相似,在此不作赘述。
不限于上述实施例,所述导光模组13还可以是遮光元件,即所述遮光元件遮挡部分所述光源11产生的光束传输至所述入光面300,并在所述入光面300形成光照区域和非光照区域。所述光照区域为接收所述光束的区域,所述非光照区域为没有光束覆盖的区域。如果所 述导光模组13遮挡部分光束在所述入光面300形成连续且相互平行的所述光照区域和所述非光照区域,则在沿所述光照区域和所述非光照区域相互平行方向的第一维方向上,所述入光面300会形成光强均匀的光照,而在垂直所述第一维方向的第二维方向上,所述入光面300会形成光强非均匀的光照。

请参阅图22,是图21所示光电转换器组31中光电转换器35的一较佳实施例平面结构示意图。所述光电转换器35是设于同一承载基板的光伏组件,其包括多个相互绝缘设置的光电转换单元带351和多个内部输出端子352。
沿平行于Y轴方向,在每一光电转换器35中,所述多个光电转换单元带351相互平行间隔设置,分别是:第一光电转换单元带3511、第二光电转换单元带3512、第三光电转换单元带3513、......、第M-1光电转换单元带351(M-1)及第M光电转换单元带351M。所述多个光电转换单元带351沿Y轴方向彼此电位隔离。
所述多个内部输出端子352分别设于所述多个光电转换单元带351的端部,其中每一内部输出端子352对应与其中一光电转换单元带351分别电连接,用于串联连接相邻光电转换器35的光电转换单元带351,实现沿X轴方向相邻光电转换器35的光电转换单元带351的电连接。所述内部输出端子352包括正极连接端3521和负极连接端3522,所述正极连接端352连接所述光电转换单元带351的正极,所述负极连接端3522连接所述光电转换单元带351的负极。
请参阅图23a、23b,分别是图21所示光电转换器组及光电转换单元带组的结构示意图。在所述光电转换器组31中,沿着平行于Y 轴方向,每一光电转换单元带351沿着平行于X轴方向延伸设置,相邻光电转换器35的光电转换单元带351分别通过所述正极连接端3521和负极连接端3522对应电连接,即:所述第一光电转换器35的第一光电转换单元带3511与第二光电转换器35的第一光电转换单元带3511对应电连接,所述第二光电转换器35的第一光电转换单元带3511与所述第三光电转换器35的第一光电转换单元带3511对应电连接,......,所述第N-1光电转换器35的第一光电转换单元带3511与所述第N光电转换器35的第一光电转换单元带3511对应电连接,由此获得由每一光电转换器35的第一光电转换单元带3511串联形成的第一光电转换单元带组371。
同时,所述第一光电转换器35的第二光电转换单元带3512与第二光电转换器35的第二光电转换单元带3512对应电连接,所述第二光电转换器35的第二光电转换单元带3512与所述第三光电转换器35的第二光电转换单元带3512对应电连接,......,所述第N-1光电转换器35的第二光电转换单元带3512与所述第N光电转换器35的第二光电转换单元带3512对应电连接,由此获得由每一光电转换器35的第二光电转换单元带3512串联形成的第二光电转换单元带组372。
以此类推,所述第一光电转换器35的第M光电转换单元带351M与第二光电转换器35的第M光电转换单元带351M对应电连接;所述第二光电转换器35的第M光电转换单元带351M与第三光电转换器35的第M光电转换单元带351M对应电连接;......,所述第N-1光电转换器35的第M光电转换单元带351M与所述第N光电转换器35的第二光电转换单元带351M对应电连接,由此获得由每一光电转换器35的第M光电转换单元带串联形成的第M光电转换单元带组37M。
如此,所述光电转换器组31是由N个单行平行排列的光电转换器35线性阵列设置形成,同时也是由M行*N列阵列的多个光电转换单元带351矩阵设置形成。
综上,沿着平行于X轴方向,于每一光电转换器组31中,由于

Figure PCTCN2016000548-appb-000004
置,取每一光电转换器35中对应行光电转换单元带351构成多个平行间隔设置的光电转换单元带组37,即:第一光电转换单元带组371、第二光电转换单元带组372、......,第M光电转换单元带组37M。
在本实施例中,每个所述内部输出端子352连接一个所述光电转换单元带351,即所述光电转换器35的光电转换单元带351和内部输出端子352分别一一时应电连接。且,所述正极连接端352和所述负极连接端354设于所述光电转换器35的相异侧。
在所述光电转换器35所在平面内,界定平行于所述光电转换器35的两个相邻侧边方向分别为X轴方向和Y轴方向,且设定平行于X轴的方向为第一维方向,平行于Y轴的方向为第二维方向。因此,所述光电转换器35的多个光电转换单元带351分别平行于所述第一维方向,而且沿所述第二维方向电位隔离。
沿第一维方向,多个光电转换器35沿直线设置,形成多个相互平行的光电转换器组31,所述光电转换器组31沿所述第一维方向延伸,且相互平行间隔。
所述光电转换器35的光电转换单元带351沿平行于第一维方向延伸,相邻的不同光电转换器35的光电转换单元带351对应串联形成多组光电转换单元带组37,每一光电转换单元带组37包括多个分别来自不同光电转换器35的光电转换单元带351。于每一光电转换单元带351中,多个所述光电转换单元355相互串联并线性排布。
所述输出端30分别与所述光电转换单元带组37一一对应电连接,并对应独立输出对应的光电转换单元带组37产生的电能。
沿所述第二维方向,M代表所述光电转换单元带351的行数,如当M等于1,则表示位于第一行的光电转换单元带351,称之为第一光电转换单元带3511;同理,当M等于2,表示位于第二行的光电转换单元带351,称之为第二光电转换单元带3512,以此类推,由此,所述光电转换器35包括相互平行间隔设置的M行光电转换单元带351,分别是第一光电转换单元带3511、第二光电转换单元带3512、......、第M光电转换单元带351M。
所述光电转换器组31相互平行间隔设置,且不同的光电转换器组31之间对应串联。每一光电转换器35中,所述光电转换单元带351相互电位隔离。由来自不同光电转换器35的光电转换单元带351构成的光电转换单元带组37相互平行间隔并电位隔离设置。
请参阅图24,是图21所示光电转换器35的串接示意图。当相邻两个所述光电转换器35进行串接设置时,取相邻的光电转换器35a和光电转换器35b为例进行描述。
所述光电转换器35a包括相互平行间隔设置的M行光电转换单元带351a,分别是第一光电转换单元带351a1、第二光电转换单元带351a2、......、第M光电转换单元带351aM,以及分别与所述M行光电转换单元带351a对应连接的M个内部输出端子352a,分别是第一内部输出端子352a1、第二内部输出端子352a2、......、第M内部输出端子352aM,其中M是大于等于1的自然数。
同理,所述光电转换器35b包括相互平行间隔设置的M行光电转换单元带351b,分别是第一光电转换单元带351b1、第二光电转换单元带351b2、......、第M光电转换单元带351bM,以及分别与所述M行光电转换单元带351b对应连接的M个内部输出端子352b,分别是第一内部输出端子352b1、第二内部输出端子352b2、......、第M内部输出端子352bM。
当所述光电转换器35a和所述光电转换器35b进行串联设置时,所述光电转换器35a的第一内部输出端子352a1与所述光电转换器35b的第一内部输出端子352b1相连接,所述光电转换器35a的第二内部输出端子352a2与所述光电转换器35b的第二内部输出端子352b2相连接,......,所述光电转换器35a的第M内部输出端子352aM与所述光电转换器35b的第M内部输出端子352bM相连接。
也就是说,相邻的光电转换器35a和光电转换器35b进行串联设置时,位于所述光电转换器35a和所述光电转换器35b相同位置的光电转换单元带351分别对应串联设置。
进一步地,在所述光电转换器组31中,所述多个光电转换器35 依次串联设置。由此可知,在所述多个串联设置的光电转换器35中,所述多个光电转换器35的第一光电转换单元带3511依次串联设置,记作第一光电转换单元带组371;同理,所述多个光电转换器35的第M光电转换单元带351M依次串接串并联设置,记作第M光电转换单元带组37M。也就是说,在所述光电转换器组31内部会形成M个相互平行间隔设置的光电转换单元带组37。
其中,于每一所述光电转换单元带组37内,构成所述光电转换单元带组37的多个光电转换单元带351依次串联设置,且分别位于相对应的所述光电转换器35的相同位置。
在所述光电转换阵列100的多个依次串联设置的光电转换器组31中,位于所述多个光电转换器组31相同位置的光电转换单元带组37依次串联设置。所述光电转换器组31中光电转换单元带组37串联方式与所述光电转换器35中光电转换单元带351的串联方式相似,在此不作赘述。
所述多个输出端30是相互电位隔离的独立输出端。所述多个输出端30分别连接所述依次串接设置的光电转换单元带组37,用于独立输出相对应的所述光电转换单元带组37产生的电能。其中,每一个所述输出端30与所述依次串接设置的光电转换单元带组37对应串接设置。所述输出端30可以与负载连接,将所述光电转换阵列3产生的电能输出到所述负载。所述负载可以为电子产品、蓄电装置、逆变器、用电电器或其他合适的需要用电驱动的装置。
不限于上述实施例,所述光电转阵列3的多个光电转换器组31之间还可以存在并联连接或者串并联混合连接。
所述多个光电转换器组31之间的并联也是通过位于所述多个光电转换器组31相同位置的光电转换单元带组37对应并联实现的。具体地,如图25所示,所述多个光电转换器组21的第一光电转换单元带组271之间并联设置,所述多个光电转换器组21的第二光电转换
Figure PCTCN2016000548-appb-000005
M个光电转换单元带组27M之间并联或者串并联混合设置,以达到合理的电流电压参数。
在其他可替代实施例中,所述光电转换阵列3还可以设有一个所述光电转换器组31。当所述光电转换阵列3设有一个所述光电转换器组31时,所述多个输出端30分别连接所述M个光电转换单元带组37。每一个所述光电转换单元带组37连接一个所述输出端30,用于输出所述光电转换单元带组37产生的电能。
综上可知,在所述光电转阵列3中,所述多个依次串接的光电转换器组31内形成有依次串接的多个光电转换单元带组37,且所述多个独立的输出端30分别独立输出与其相连接的光电转换单元带带组37的电能。
所述电能输送装置5输送所述光电转换阵列3产生的电能。具体地,所述电能输出装置5包括多个逆变器(图未示),所述多个逆变器与所述多个输出端30一一对应电连接,用于独立地输送相应的所述输出端30输出的电能。其中,所述光电转换单元带组37、所述输出端30和所述逆变器依次串联连接。也就是说,所述多个逆变器通过所述多个输出端30与所述多个光电转换单元带组37对应电连接,并独立地将所述多个光电转换单元带组37产生的电能并入电网中。
当所述电能输送装置5以交流电能的方式进行电能传输时,所述电能输送装置5的逆变器可以接收所述光电转换阵列3产生的直流电能,并将所述直流电能转换为交流电能。所述电能输送装置5需要通过所述逆变器将所述光电转换阵列3产生的直流电能转变为交流电能,然后将所述交流电能直接并入电网
当然,不限于上述实施例,所述光电转换系统100还可以直流电能的形式将所述光电转换阵列3产生的电能存储起来。当所述光电转换系统100以直流电能形式存储能量时,所述光电转换系统100采用电能管理装置(图未示)代替所述电能输送装置5。具体地,所述电能管理装置包括至少一个蓄电器和一个充电控制器,所述蓄电器通过 所述充电控制器分别与所述多个光电转换单元带组37对应点连接,并将每一所述光电转换单元带组37产生的电能储存在所述蓄电器 内。
当所述光电转换系统100采用电能管理装置存储电能时,所述光电转换阵列3产生的电能可以直接存储于蓄电器。其中,所述蓄电器可以为化学电池、电容器等可以存储直流电能的蓄电装置。
当所述光电转换系统100处于光照条件下时,所述光能输出装置1可以在所述光电转换器组31表面形成均匀光照或沿所述第一维方向光能强度均匀,垂直于所述第一维方向的第二维方向的光能强度不均匀的光照。
当所述光电转换器组31处于均匀光照条件下时,所述多个独立光电转换单元带光电转换单元带组37均可以在均匀光照条件下进行光电转化,并通过所述输出端30独立地输出电能,从而实现充分利用光照的目的。
当所述光电转换器组31处于沿所述第一维方向光能强度均匀分布,而垂直于所述第一维方向的第二维方向呈非均匀分布的光照时,则在所述光电转换器组31表面可以形成沿所述第一维方向平行的多个光照带。而且,在每一所述光照带内部,所述光照的强度均匀分布;在所述多个光照带之间,所述光照的强度存在差异。
由于所述光电转换器组31的多个光电转换单元带组37沿平行于所述第一维方向直线排列,则所述光照带可以覆盖至少一个所述光电转换单元带组37。这取决于所述光照带和所述光电转换单元带组37之间的相对宽度。
在每个所述光照带内,被所述光照带覆盖的光电转换单元带组37表面具有光能强度相同的光照。在所述光电转换单元带组37内,所述多个光电转换单元带351依次串接设置,因此所述光电转换单元带组37的输出电压等于所述多个光电转换单元带351的输出电压之和,且所述光电转换单元带组37的输出电流等于单个所述光电转换单元带351的输出电流,即形成高输出电压,低输出电流的光电转换单元带组37。 在相邻所述光照带之间,由于所述相邻光照带具有光能强度不同的光照,因此,被所述相邻光照带覆盖的光电转换单元带组37表面分别具有光能强度不同的光照。在所述光电转换器组31内,相邻光电转换单元带组37之间绝缘间隔设置。因此,每一所述光电转换单元带组37各自独立在不同光能强度的光照条件下进行光电转化,相互之间互不干扰,即具有不同光能强度的光照带均可以被所述光电转换器组31充分利用而分别产生电能。
进一步地,在所述光电转换系统100的光电转换阵列3中,所述多个光电转换器组31的依次串接设置是通过位于所述多个光电转换器组31相同位置的光电转换单元带组37依次串接设置实现的。而且,所述依次串接设置的光电转换单元带组37与所述独立的输出端30对应串接设置,用于独立输出相对应的所述依次串接的光电转换单元带组37产生的电能。也就是说,所述光电转换阵列3的多个输出端30均是以高输出电压,低输出电流的方式进行输出电能,而且所述光电转换阵列3输出的总电能等于所述多个依次串接的光电转换单元带组37输出的电能之和。
相较于现有技术,在所述光电转换系统100的光电转换阵列3中,每一光电转换器组31内部形成多个光电转换单元带组37,且所述光电转换单元带组37分别连接多个独立的输出端30以实现电能的独立输出,从而使得所述光电转换系统100可以充分利用所述光能输出装置1在所述光电转换器组31表面形成均匀光照或沿所述第一维方向光能强度均匀,垂直于所述第一维方向的第二维方向的光能强度不均

端30输出电能的方式可以降低电能传输损耗。
