因此， 于现有的太阳能电池的技术上， 使得太阳光无法被有效地利用， 需 要多波段太阳能吸收技术， 以更加有效地利用不同波段的太阳能。
传统多波段太阳能吸收技术所使用的是垂直堆栈技术，即串接式太阳电池
( tandem solar cel l ) 。 串接式太阳电池是将两个或三个不同的太阳能电池 在垂直方向上堆栈在一起， 以增加太阳能电池的吸收频谱。但是由于材料本身 的穿透率， 越下层的材料层的通光量会越低， 因而降低其吸光量。
并且， 具有不同吸收频谱的太阳能电池具有不同的晶格常数 （lattice constant ) 。 晶格常数的不匹配容易在交界处产生一些缺陷， 因而影响其光电 流的收集。 因此， 在交界处则需多堆栈一层材料， 以降低交界处的电阻值， 同 时解决晶格常数不匹配的问题， 但是却相对地增加了制作的成本和复杂度。于 垂直堆栈技术上， 可堆栈三个太阳能电池和四个太阳能电池，但是随着堆栈层 数的增加， 制作的成本和复杂度也随着增加， 而提升的效率不一定呈线性的增 力口， 并影响工艺的成品率。
于太阳能电池缺料的压力下，集光器的使用便略显重要。集光比的定义为 集光器的受光面积比上在聚光斑上所放置太阳能电池的受光面积。当具有越高 集光比的太阳能发电系统， 所使用的太阳能电池材料也会越少。
在一现有技术中， 利用拱形菲涅尔透镜 （arched Fresnel lens ) 将太阳 光集光到太阳能电池上， 以提高入射光的强度并降低太阳能材料的使用率。但 是太阳能电池的吸收频谱有别于太阳光的发光频谱，未吸收的太阳能会转换成 热能， 因而提高了太阳能电池基板的温度， 如此一来便降低了太阳能电池的转 换效率。因此需要额外设计散热片。但是散热片的设计却增加了太阳能发电系 统的成本与复杂度。
在另一现有技术中， 则采用离轴菲涅尔透镜 （off-axis Fresnel lens ) 的设计。根据离轴菲涅尔透镜的设计原理，不同波长会因为高色散材质的特性， 而集光在光入射轴向 （axial direction) 上不同的位置。 接着， 将不同的太 阳能电池放置于光入射轴向的附近，使得不同波长的光可以被不同的太阳能电 池吸收。 但如此的设计会造成入射光会具有较大的入射角度而影响收光效率， 并且高色散材质具有不易取得的问题。
相关技术与研究可参考美国专利第 6, 281, 426号、 第 5, 498, 297号及第 4， 204， 881号等。 发明公开

下面结合附图对本发明的结构原理和工作原理作具体的描述: 于本发明中， 利用多波段集光器将入射光源如太阳光或其它光线， 分出不 同波段的光束，并使其集光在光入射横向上不同的位置，以形成不同的聚光斑。 前述不同波段的光束可以是指在不同光频谱范围区间， 或指特定光波长。 以下 为了便于说明， 将以太阳光为例， 但本发明并不以此为限， 亦可为环境光或其 它光线。
接着， 在各个聚光斑上， 设置对应的能量转换组件。此处的能量转换组件 可以是但不限于光电转换组件或热电转换组件。前述对应设置， 可以是将前述 的能量转换组件的吸收频谱峰值与聚光斑的光束的波段 (波长)相对应 (注： 能 量转换组件对太阳光具有不同的吸收频谱峰值）， 举例而言， 若能量转换组件 吸收频谱峰值为 500纳米 (nm)，则将的配置于光束的光波段涵盖此峰值的聚光 斑处即可。如此一来， 各能量转换组件即可具有良好的转换效率， 进而提升总 能量转换效率。 同时， 又可降低热能的产生。 于此， 由于多波段集光器具有集 光的特性， 因此可以提高多波段集光器的集光比， 以及降低能量转换组件材料 的使用率。
图 3为根据本发明的多波段集光及能量转换模块的示意图。多波段集光及 能量转换模块 100包括多波段集光器 110和能量转换组件组 130。 多波段集光 器 110包括一光栅 114和集光组件 112。 其中， 光栅 114位于集光组件 112的 一表面上。 多波段集光器 110 的集光组件 112将入射光源集光于一集光面 A 上。光栅 114将入射于多波段集光器 110的入射光源依波段分光， 以形成多个 光束， 例如可将入射的太阳光 102依据不同的波长 λ 1、 λ 2和 λ 3分为三波段 光束。此三波段光束虽为特定波长为例， 但并不以此为限， 亦可以是三个相异 波长范围的波段光束， 例如以 λ 1、 λ 2和 λ 3为中心波长的三个波段的光束。 至于多波段集光器 110先将太阳光 102分光再进行集光，或先进行集光再分光， 均能达成本发明的目的。 本实施例先行分光后再集光。
前述的集光面 Α在本实施例中虽以一平面方式示意，但并不以此为限，集 光面 A亦可以是对应集光组件 112的集光特性而变化，例如一曲面或依序连接 的多个线段。
能量转换组件组 130包含有多个光电转换组件或热电转换组件，前述的多 个能量转换组件对光线 (光能量)具有不同的吸收频谱峰值。在本实施例中， 能 量转换组件组 130包含三个能量转换组件 131、 132、 133，且能量转换组件 131、 132、 133具有不同的吸收波段（吸收频谱峰值）。该些能量转换组件 131、 132、 133侧边相邻地设置， 各个能量转换组件 132/133的吸收波段可接续相邻配置 的前一能量转换组件 131/132 的吸收波段， 即能量转换组件 131、 132、 133 的吸收波段不重叠。 能量转换组件组 130设置于集光组件 112的集光面 A上， 且能量转换组件组 130的收光面 130a (即各能量转换组件 131、 132、 133的 收光面 130a)面向集光组件 112，使集光后的光线能入射至能量转换组件 131、 132、 133中。要说的是，在此虽列举能量转换组件组 130的能量转换组件 131、 132、 133侧边相邻设置为例， 但并不以此为限， 只要能量转换组件组 130设 置在集光组件 112 的集光面 A上， 使集光后的光线能入射至能量转换组件组 130中即可。 此外， 集光面 A可与集光组件 112的光轴 L形成一夹角。 此夹角 可介于 60度到 120度之间。 在一实施例中， 集光面 A可大致上垂直于集光组 件 112的光轴 L。
依本实施例，太阳光经过光栅 114及集光组件 112后会形成具有相异波段 的多个光束，这些光束在集光面 A上形成聚光斑，而各能量转换组件 131、 132、 133则依其吸收光谱峰值对应配置于各光束所形成的聚光斑位置， 因此， 能量 转换组件 131、 132、 133另一列举配置方式则是将各能量转换组件 131、 132、 133收光面 130a的中心轴（即为其垂直入射的轴）对应于各光束的光轴， 意即， 能量转换组件 131、 132、 133收光面 130a的中心轴与与其对应的光束的光轴 L间的夹角在 0度到 20度之间（或 160度到 180度之间）， 能得到良好的收光 效果， 进一歩提升能量转换效率。
集光组件 112包含一出射面 112a与一入射面 112b， 其中入射面 112b用 以接收入射光源， 经由出射面 112a出光并集光于集光面 A上。 其中， 集光组 件 112的出射面 112a的大小可覆盖能量转换组件组 130的收光面 130a。在一 实施例中， 能量转换组件组 130的宽度 D' 可小于或等于集光组件 112的宽度 D的二分之一。 在另一实施例中， 能量转换组件组 130的收光面 130a小于或 等于集光组件 112的出射面 112a垂直投影在水平面上的面积的二分之一。
光栅 114可贴合或制作于集光组件 112的一侧的表面上。换言之， 集光组 件 112和光栅 114可为独立的两组件， 或者为一体成型的单一构件。 如图 3 所示， 光栅 114贴合于集光组件 112的入射面 112b上。 此外， 集光组件 112 可为透镜， 在本实施例中， 该集光组件 112为一双凸透镜， 但不以此为限。 当太阳光 102进入到多波段集光及能量转换模块 100时，会先经过多波段 集光器 110， 经由多波段集光器 110的分光与集光后， 形成多个不同波段的光 束入射到能量转换组件组 130。 在图 3的实施例中， 太阳光 102经过多波段集 光器 110时， 首先进入到光栅 114， 将入射的太阳光 102分光为三个不同波长 的光束， 并经由入射面 112b入射至集光组件 112， 分光后的光束于集光组件 112集光后， 会经由出射面 112a的出光， 而在集光面 A上依不同波长 （入 1、 入 2和 λ 3 ) 集光到不同的聚光斑上。 能量转换组件组 130中的能量转换组件
131、 132、 133设置在这些聚光斑上。 详细来说， 各能量转换组件 131、 132、 133设置在其相对应吸收频谱峰值的不同波段光束的聚光斑上。 gp， 能量转换 组件 131、 132、 133的吸收频谱峰值会相应于形成其设置处上的聚光斑的光的 波长 （λ 1、 λ 2和 λ 3 ) 。 换言之， 能量转换组件 131、 132、 133的吸收波段 会包含对应的波长（λ 1、 λ 2或 λ 3 ) 。 或者是， 对应的波长（λ 1、 λ 2或入 3 ) 位于能量转换组件 131、 132或 133的吸收频谱的中央。
于此， 集光组件 112可致使太阳光 102 (即入射光源）在集光后以小角度 的入射角入射至各个能量转换组件 131、 132、 133。 在一实施例中， 此入射角 可介于一 30度到 30度之间。此处的入射角指入射的光束与能量转换组件 131、
132、 133收光面 130a的法线之间的夹角。
请参考图 4， 与图 3的实施例不同之处在于， 本实施例所采用的集光组件 112为平凸透镜。同样地，当太阳光 102进入到多波段集光及能量转换模块 100 时， 会先经过多波段集光器 110， 经由多波段集光器 110的分光与集光后， 形 成多个不同波段的光束入射到能量转换组件组 130。
请参考图 5， 与图 3、 图 4的实施例不同之处在于， 本实施例所采用的集 光组件 112为菲涅尔透镜 （Fresnel lens ) 。 在一实施例中， 菲涅尔透镜可使 用二维集光式菲涅尔透镜。 此外， 菲涅尔透镜也可为一维集光式。 同样地， 当 太阳光 102进入到多波段集光及能量转换模块 100时，会先经过多波段集光器 110， 经由多波段集光器 110的分光与集光后， 形成多个不同波段的光束入射 到能量转换组件组 130。
请参考图 6， 与图 3的实施例不同之处在于， 本实施例中的光栅 114设置 于集光组件 112的出射面 112a上。 因此， 当太阳光 102进入到多波段集光器 110时，首先经由入射面 112b入射至集光组件 112，并于集光组件 112集光后， 会经由出射面 112a的出光， 而进入到光栅 114中， 并将集光后的太阳光 102 分光为三个不同波长的光束， 在集光面 A上依不同波长 （λ 1、 λ 2和 λ 3 )集 光到不同的聚光斑上， 而被设置在相对应位置的能量转换组件 131、 132、 133 所接收。 由上述的实施例可知， 在多波段集光器 110中， 光栅 114可设置于集 光组件 112的入射面 112b或出射面 112a， 并不以此为限。
请参考图 7， 与图 6的实施例不同之处在于， 本实施例所采用的集光组件 112为平凸透镜。 由于光栅 114设置于集光组件 112的出射面 112a (即平凸透 镜的平面）上， 因此， 在本实施例中， 所使用的光栅 114可为等周期光栅， 即 光栅 114投影到平凸透镜中的曲面的切线 TL的周期（间距（pitch) )均相等。 而图 6的实施例， 光栅 114设置于集光组件 112的出射面 112a (即双凸透镜 的凸面）上， 所使用的光栅 114亦可为等周期光栅， 即光栅 114投影到双凸透 镜的切线 TL的周期 （间距） 均相等。 要说的是， 在此仅列举光栅 114投影到 切线 TL的周期可为等周期的设计， 本领域技术人员当知光栅 114的周期可有 不同设计的变化， 并不以所列举者为限。
请参照图 8， 图示为一反射式的多波段集光及能量转换模块 100， 与前述 实施例所不同的是，太阳光 102是来自于相对应于能量转换组件组 130的收光 面 130a背面方向入光 （进入多波段集光器 110 ) ， 而非如前述实施例的太阳 光 102由能量转换组件组 130的收光面 130a方向入光。因此，在本实施例中， 采用的集光组件 112可为反射式集光透镜， 其中可于集光组件 112 的出射面 112a或入射面 112b形成反射面，且光栅 114形成于集光组件 112的出射面 112a 上。 当太阳光 102进入到多波段集光器 110时， 先经由光栅 114的分光后， 进 入到集光组件 112中进行集光， 由于出射面 112a或入射面 112b为反射面， 因 此分光后的光束会在集光组件 112中反射， 并集光在集光面 A上， 再进入到位 于集光面 A的能量转换组件组 130。 在另一实施例中， 多波段集光器 110可一 体成型， 即集光组件 112与光栅 114为一体， 此时， 可在光栅 114的表面上设 置反射层， 例如是涂布金属。 当太阳光 102进入到多波段集光器 110时， 会直 接在光栅 114中反射、 集光与分光， 同样使得光源集光在集光面 A上。
多波段集光及能量转换模块 100在实际的设计上，举例来说，可参照图 9， 于此采用双凸透镜作为集光组件 112， 光栅 114可设计成将入射光依照波长分 光为 λ 1、 λ 2禾 Π λ 3的三波段光， 其中 λ 1=500 讓、 λ 2=600 nm以及 λ 3=700 nm, 其相对应设置在集光面 A聚光斑位置的能量转换组件 131、 132、 133， 可 选择如图 2中的能量转换组件 131， 132， 133， 分别对于波长为 500 nm、 600 nm 以及 700 nm的波段光具有良好的吸收系数。 当太阳光 102垂直入射时， 多波 段集光及能量转换模块 100的设计条件可为集光组件 112的宽度 D和厚度 T 分别为 8 cm和 1 cm, 集光组件 112所使用材质的折射率为 1. 49、 集光组件 112的曲率半径 （R) 为 12. 8 cm、 光栅 114投影到切线 TL的周期 d为 5 mm、 光栅 114的绕射阶数 （m) 为 -1、 能量转换组件组 130的总宽度 D' 为 1. 5 cm 以及集光组件 112的入射面 112b的中心点到能量转换组件 131、 132、 133收 光面 130a的中心点的联机 Hl、 H2、 H3长度分别为 27. 60cm, 27. 63 cm和 27. 66 cm,联机 Hl、 H2、 H3与收光面 130a法线的夹角分别为 5. 74° 、 6. 89° 和 8. 05 此外， 参照图 10， 光栅 114可由二个以上的次光栅 115、 116所构成。 该 些次光栅 115、 116可交错排列。再者， 该些次光栅 115、 116可具有相同周期， 亦可具有不同周期， 可依实际需求而有不同的设计。 于此， 各个次光栅 115、 116可将入射光源在集光面 A上形成各自的次聚光斑， 以至于透过次聚光斑的 叠加来得到一中心平坦的总聚光斑 3， 进而避免能量过度集中。 换言之， 对应 于各个能量转换组件 131、 132、 133的各个聚光斑可由二个以上的次聚光斑所 构成。 如此即可避免因能量过度集中而造成能量转换组件组 130的温度上升。 关于前述次聚光斑与总聚光斑的示意图请参考图 11，图中的水平轴为集光面 A 的水平位置，垂直轴则为相对强度， 从图中可以看出， 多个邻近的次聚光斑 1、 2集结而成一个总聚光斑 3 (图中仅以次聚光斑 1及次聚光斑 2示意，但并非本 发明的限制）。
参照图 12， 在一太阳能发电系统 10中， 可设置有二个以上的多波段集光 及能量转换模块 100-1、 100-2、 100-3。
该些多波段集光及能量转换模块 100-1、 100-2、 100-3可并排配置。 即， 多波段集光及能量转换模块 100-1、 100-2、 100-3 的多波段集光器 110-1、 110-2、 110-3侧边相邻地依序配置。而不同多波段集光及能量转换模块 100-1、 100-2、 100-3的能量转换组件组 130-1、 130-2、 130-3则不相互邻接， 即彼 此间隔开。
根据本发明的多波段集光及能量转换模块， 利用多波段集光器（集光组件 和光栅）将太阳光分出不同波段的光束， 并使其集光于各自对应的能量转换组 件， 以致使能量转换组件具有良好的转换效率， 进而提升总能量转换效率。并 且， 多波段集光器的使用还可降低能量转换组件材料的使用率。
最后， 请参阅图 13， 其为根据本发明七实施例的多波段集光及能量转换 模块的结构示意图。 多波段集光及能量转换模块 100包括多波段集光器 110、 能量转换组件组 130、 以及配置于多波段集光器 110与能量转换组件组 130之 间的二次镜 140。 多波段集光器 110包括光栅 114和集光组件 112。 多波段集 光器 110的集光组件 112将入射光源集光于一集光面 A上。光栅 114将入射于 多波段集光器 110的入射光源依波段分光为光束。二次镜 140用以导引被分光 与集光的光束于多个聚光斑。 因此， 当被集光的光束经过二次镜 140后， 可以 减少光束入射于能量转换组件组 130的入射角的偏差，而不致造成聚光斑偏离 能量转换组件组 130。 因此， 能量转换组件组 130即可依据其吸收波段将入射 光线做能量转换。
当然， 本发明还可有其它多种实施例， 在不背离本发明精神及其实质的情 况下， 熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 工业应用性
本发明的多波段集光及能量转换模块， 利用多波段集光器（集光组件和光 栅）将太阳光或其它光线（即入射光源）分出不同波段的光束， 并使其集光于 各自对应的能量转换组件， 以使能量转换组件能转换其所对应波长的光束， 而 得到良好的能量转换效率， 进而提升总能量转换效率。并且， 多波段集光器的 使用还可降低能量转换组件材料的使用率。另外，集光后的太阳光或其它光线 可以小角度入射至能量转换组件， 可降低太阳光或其它光线的反射率。
