Description

聚光型太阳能电池模块的二次聚光装置 技术领域
本发明提供一种二次聚光装置， 特别是关于一种设于聚光型太阳能电池模块内 的管件， 并涉及该管件的一反光通道。 背景技术 '
传统的聚光型太阳能电池模块， 一般是由反射镜及聚光型太阳能电池 (Concentrator Photovoltaic, CPV) 组配而成， 通常是在一壳体内形成一聚光用腔室， 该聚光型太阳能电池设于腔室内， 且反射镜配置于腔室顶部的壳体壁面上， 以反射 外界太阳光至腔室内， 令聚光型太阳能电池接受反射镜反射的太阳光照射而发电； 目前利用反射镜聚光的作法， 包括有利用菲涅尔透镜 (Fresnel Lenes)及盖赛格林式 (Cassegrain)光学系统等。
且知，上述聚光型太阳能电池的主要材料为砷化镓 (GaAs)，也就是三五族 (III-V) 材料， 一般采用硅晶材料制成的太阳能电池只能吸收太阳光语中 400 ~ l，100nm 波 长的能量， 而聚光型不同于硅晶圓太阳能技术， 可透过多接面化合物半导体吸收较 宽广的太阳光傳能量， 且聚光型太阳能电池的耐热性比一般晶圆型太阳能电池又来 的高； 因此， 可通过使用较大面积的反射镜将外界太阳光聚焦至较小面积的聚光型 太阳能电池上， 来提高太阳能的发电效率， 并节省电池使用面积。
现有的聚光型太阳能电池模块的聚光技术， 可见揭露于中国台湾省第
201015733号及第 M360983号专利案中； 然而， 其中的反射镜于反射太阳光照射聚 光型太阳能电池期间， 反射至腔室内的太阳光也容易辐射至聚光型太阳能电池周围 的区域， 而使该太阳能电池所能接收的太阳光的辐射能产生一定程度的衰减；此外， 该反射镜也容易受到外界环境或人为因素的影响， 而使反射镜所反射至太阳能电池 表面的多道太阳光线之间形成强、 弱上的差异， 导致太阳能电池表面接受太阳光照 射的强度不均匀。
因此， 现有较为先进的-技术中， 已存在一种可将太阳光聚焦于太阳能电池上的 聚光器， 揭露于中国台湾省第 1277772号专利案中， 其中的聚光器呈浅薄的杯状， 且反射镜所反射的太阳光可直接穿过该聚光器而聚焦于聚光型太阳能电池表面； 如 此， 虽能利用聚光器的内壁遮挡太阳光辐射至太阳能电池周围的区域， 但其反射镜 反射的太阳光直接聚焦于太阳能电池表面， 而具有上述太阳能电池表面接受太阳光 照射的强度不均匀的状况， 亟需加以改善。 发明内容

一反光通道， 形成于该宽管口及该窄管口之间， 且该反光通道自该宽管口朝该 窄管口方向逐渐缩口， 该反光通道并具有一可供所述太阳光于该反光通道内进行多 次反射的特定长度， 该特定长度依据其所反射的太阳光的波长加以设定。
藉由上述， 经由该反射镜反射至聚光区内的多道太阳光线， 能够聚焦于该管件 的宽管口， 进而透入该反光通道内， 致使所述太阳光线于该反光通道内进行多次反 射， 且所述太阳光线的反射次数受到该反光通道的逐渐缩口的内壁影响， 而朝该窄 管口方向逐渐增多， 因此能够反射所述太阳光经由该窄管口均匀照射该受光端面， 驱使该太阳能电池芯片发电； 据此， 以确保太阳能电池芯片的正常发电效率。其中， 更加包含一壳体， 内部形成一腔室， 且该壳体顶部形成一可供太阳光照射进入 的窗口， 而与该腔室相连通， 该反射镜配置于该窗口， 以间隔该腔室形成该聚光区。
所述反射镜以弧凹形态向下方伸入该腔室内， 而于该反射镜上形成一朝向上方 的弧凹状反光面， 该聚光区位于该窗口与该弧凹状反光面之间。 该窗口配置一辅助 镜， 位于该反射镜上方， 该太阳能电池芯片位于该弧凹状反光面上， 该反射镜经由 该弧凹状反光面反射太阳光照射该辅助镜， 且该辅助镜上具有一可接受该弧凹状反 光面反射的太阳光照射的弧凸状反光面， 能够反射太阳光照射该太阳能电池芯片。 或者， 该太阳能电池芯片邻近该窗口， 并位于该反射镜的该弧凹状反光面上方， 该 反射镜经由该弧凹状反光面反射太阳光照射该太阳能电池芯片。
或者， 所述反射镜可为一凸透镜或一菲涅尔透镜。 此外， 本发明也包含：
所述管件可由非透光材料制成， 而使反光通道内壁能够遮挡太阳光辐射至太阳 能电池芯片周围的区域。
所述管件可为矩形管或圆形管， 以利于管件的加工。
所述反光通道内壁形成有一可供所述太阳光于该反光通道内进行多次反射的 反光面； 且该反光面由高反射率的反光材料布设而成， 该反光材料可为铝或银等。
与现有技术相比， 本发明所述的聚光型太阳能电池模块的二次聚光装置， 克服 了现有技术中， 由于多道太阳光线之间强、 弱上的差异， 而导致太阳能电池表面接 受太阳光照射强度不均匀的问题。 然而， 为能明确且充分揭露本发明， 并予列举较 佳实施的图例， 以详细说明其实施方式如后述： 附图说明

首观图 1所示， 揭示出本发明第一款实施例的立体分解图， 并配合图 2及图 3 说明本发明聚光型太阳能电池模块的二次聚光装置， 包含一壳体 1、 一反射镜 2、 一聚光型太阳能电池芯片 3、 一管件 4及一反光通道 40; 该壳体 1内部形成一腔室 11， 且壳体 1顶部形成一可供太阳光照射进入的窗口 12, 而与该腔室 11相连通。 该反射镜 2配置于该窗口 12, 能够反射外界太阳光至反射镜 2近侧的腔室 11 内聚 焦， 而于腔室 11 内形成一聚光区 13; 该反射镜 2在本实施上可呈弧凹状， 且反射 镜 2中央以弧凹形态向下方伸入该腔室 11 内， 而于该反射镜 2顶部形成一朝向上 方的弧凹状反光面 21 , 并间隔腔室 11形成该聚光区 13 , 致使聚光区 13位于该窗 口 12与弧凹状反光面 21之间， 且该反射镜 2是经由弧凹状反光面 21反射外界太 阳光进入该聚光区 13内聚焦。
该窗口 12设有一透镜 6 (如图 1及图 3所示） ， 位于该反射镜 2顶部， 该透镜 6可由玻璃或聚光胶材构成， 且窗口 12中央并配置有一辅助镜 5 , 位于该透镜 6中 央底面， 并位于该反射镜 2的弧凹状反光面 21中央上方的聚光区 13内； 该太阳能 电池芯片 3配置于该腔室 1 1的聚光区 13 内， 并位于该弧凹状反光面 21 中央， 且 太阳能电池芯片 3的一受光端面 31朝向该反射镜 2反射至该聚光区 13的太阳光； 该反射镜 2的反射面积大于该辅助镜 5的反射面积， 且辅助镜 5的反射面积大于该 太阳能电池芯片 3的受光端面 31的面积， 而使该反射镜 2、 辅助镜 5及太阳能电池 芯片 3之间配置形成一盖赛格林式光学系统； 如此， 该反射镜 2能够经由该弧凹状 反光面 21反射外界太阳光照射该辅助镜 5 ,且辅助镜 5底部具有一朝向下方的弧凸 状反光面 51， 能够接受该弧凹状反光面 21反射的太阳光照射， 并能够反射太阳光 照射该太阳能电池芯片 3的受光端面 31 ,致使太阳能电池芯片 3接受该反射镜 2及 辅助镜 5反射的太阳光照射而发电。
该管件 4座落于该聚光区 13 内 （如图 1及图 3所示） ， 并邻近于该太阳能电 池芯片 3顶端， 且管件 4双端分别形成一位于该反射镜 2反射太阳光的聚焦位置的 宽管口 41 (如图 2及图 4所示） ， 及一位于该受光端面 31的相对端的窄管口 42; 实际上， 该管件 4可垂直配置于该太阳能电池芯片 3顶端， 且管件 4底端固定于该 弧凹状反光面 21顶部中央， 而使管件 4底端的窄管口 42罩住太阳能电池芯片 3的 受光端面 31 , 且管件 4顶端的宽管口 41朝向该辅助镜 5的弧凸状反光面 51 , 并位 于该反射镜 2经由辅助镜 5反射太阳光的聚焦位置； 该管件 4可由非透光的金属、 塑料或陶瓷材料制成， 且管件 4、 4a可为矩形管或圓形管 （如图 5所示） , 以利于 管件 4的加工。
该反光通道 40形成于该宽管口 41及窄管口 42之间 （如图 2及图 4所示） ， 且反光通道 40自该宽管口 41朝窄管口 42方向逐渐缩小直径， 而使反光通道 40呈 上宽下窄的斜锥状； 该反光通道 40并具有一可供所述太阳光于该反光通道 40内进 行多次反射的特定长度 hi ,该特定长度 hi依据其所反射的太阳光的波长加以设定； 实质上， 该反光通道 40 内壁以镀膜方式披覆形成有一可供所述太阳光于该反光通 道 40内进行多次反射的反光面 43 ,且反光面 43可由高反射率的反光材料布设而成， 该反光材料可为铝或银等； 此外， 由于该管件 4可由非透光材料制成， 因此， 该反 光通道 40内壁亦能够遮挡太阳光辐射至太阳能电池芯片 3周围的区域。 藉由上述， 可供据以实施本发明， 特别是当太阳光照射该壳体 1顶面时 （如图 3所示） ， 太阳光线 7能够通过该透镜 6进入聚光区 13， 并照射该反射镜 2的弧凹 状反光面 21， 且弧凹状反光面 21会反射多道太阳光线 7照射该辅助镜 5的弧凸状 反光面 51 , 同时该弧凸状反光面 51会反射多道太阳光线 7聚焦于该管件 4顶端的 宽管口 41， 进而透入该反光通道 40内 （如图 4所示） , 致使所述太阳光线 7于该 反光通道 40内壁的反光面 43上进行多次反射， 且所述太阳光线 7的反射次数受到 该反光通道 40的逐渐缩口的内壁的反光面 43影响， 而朝该窄管口 42方向逐渐增 多； 因此， 能够反射所述太阳光线 7经由该窄管口 42均匀照射该受光端面 31 , 驱 使该太阳能电池芯片 3发电； 据此， 以确保太阳能电池芯片 3的正常发电效率。
请参阅图 6所示， 揭示出本发明第二款实施例的剖示图， 说明其于上述第一款 实施例相异之处在于，该反射镜 2a可为一凸透镜或一菲涅尔透镜， 并省略上述透镜 及辅助镜等构件， 该反射镜 2a下方的腔室 1 1形成该聚光区 13， 且太阳能电池芯片 3位于反射镜 2a中央下方的腔室 1 1内壁面上， 该反射镜 2a的反射面积大于该太阳 能电池芯片 3的受光端面 31的面积； 如此， 当太阳光照射该壳体 1顶面时， 太阳 光线 7会接受该反射镜 2a折射， 而使多道太阳光线 7 聚焦于该管件 4顶端的宽管 口 41 , 进而透入该反光通道 40内， 致使所述太阳光线 7于反光通道 40内壁的反光 面 43上进行多次反射， 能够反射所述太阳光线 7经由窄管口 42均匀照射受光端面 31 , 驱使该太阳能电池芯片 3发电， 其余构件组成及实施方式等同于上述第一款实 施例。
请参阅图 7所示， 揭示出本发明第三款实施例的剖示图， 说明其于上述第一款 实施例相异之处在于， 省略上述辅助镜， 该太阳能电池芯片 3位于该透镜 6中央底 面， 而邻近该窗口 12， 且太阳能电池芯片 3位于该反射镜 2的弧凹状反光面 21中 央上方的聚光区 13 内； 该管件 4可垂直配置于该太阳能电池芯片 3下方， 而位于 透镜 6中央底面， 该管件 4的窄管口 42罩住太阳能电池芯片 3的受光端面 31 , 且 管件 4的宽管口 41朝向该反射镜 2的弧凹状反光面 21， 并位于反射镜 2反射太阳 光的聚焦位置； 该反射镜 2的反射面积大于该太阳能电池芯片 3的受光端面 31的 面积； 如此， 当太阳光照射该壳体 1顶面时， 太阳光线 7能够通过透镜 6照射反射 镜 2的弧凹状反光面 21， 且弧凹状反光面 21会反射多道太阳光线 7聚焦于管件 4 的宽管口 41 , 进而透入该反光通道 40内， 致使所述太阳光线 7于反光通道 40内壁 的反光面 43上进行多次反射， 能够反射所述太阳光线 7经由窄管口 42均匀照射受 光端面 31 , 驱使该太阳能电池芯片 3发电， 其余构件组成及实施方式等同于上述第 一款实施例。
以上说明对本发明而言只是说明性的， 而非限制性的， 本领域普通技术人员理 解， 在不脱离权利要求所限定的精神和范围的情况下， 可作出许多修改、 变化或等 效， 但都将落入本发明的保护范围之内。
