近几年来, 由于世界各地的原油存量逐年的减少, 能源问题已成为全球注 目的焦点。 为了解决能源耗竭的危机, 各种替代能源的发展与利用实为当务的 急。 随着环保意识抬头, 加上太阳能具有零污染、 以及取之不尽用之不竭的优 点, 太阳能已成为相关领域中最受瞩目的焦点。 因此, 在日照充足的位置, 例 如建筑物屋顶、 广场等等, 愈来愈常见到太阳能面板的装设。
太阳能模块主要包括太阳能电池、 封装材、 背板与用于将太阳能电池、 封 装材及背板固定于其中的框架。 为提升太阳能模块的输出功率, 太阳能模块中 一般多是使用悍带 (nbbon)连接各个太阳能电池。然而, 由于悍带本身具有反射 性, 因此, 照射到悍带的太阳光容易被直接反射掉而无法被利用, 大约会造成 2.5%-3%的功率损失。 发明内容
本发明的目的就是在提供一种图案化悍带的装置,以在悍带表面形成图案, 用以提升太阳能电池的发电效率。
依照本发明的一态样, 提出一种图案化悍带的装置, 用以图案化悍带, 悍 带具有相对的第一锡层与第二锡层。 图案化悍带的装置包含输送平台、 定位元 件、 加热元件、 压纹元件以及控制单元。 太阳能电池置于输送平台上。 定位元 件设置于输送平台上方, 并相对于输送平台上下移动, 以定位悍带于太阳能电 池的表面, 第一锡层接触该太阳能电池。 加热元件设置于输送平台上方, 以液 化第一锡层与第二锡层, 使悍带串悍于太阳能电池。 压纹元件设置于输送平台 上方, 并相对于输送平台上下移动, 以接触液化的第二锡层而在第二锡层表面 形成一图案, 其中第一锡层与太阳能电池之间的表面张力大于第二锡层与压纹 元件之间的表面张力。 控制单元与输送平台、 定位元件、 加热元件与压纹元件 电性连接, 以控制输送平台、 定位元件、 加热元件与压纹元件。 在一实施例中, 加热元件为接触式加热元件, 压纹元件与加热元件可以整 合为热压单元。 热压单元的材料为与该第二锡层具有大表面张力的材料。 热压 单元包含起伏表面, 起伏表面的起伏高度小于悍带的该图案的起伏高度。 图案 化悍带的装置更包含助悍剂, 分布于第二锡层上。
另一实施例中, 加热元件为非接触式加热元件, 定位元件、 加热元件与压 纹元件分别为独立元件。 压纹元件的材料为与该第二锡层具有小表面张力的材 料。压纹元件包含起伏表面,起伏表面的起伏高度等于悍带的图案的起伏高度。 定位元件接触悍带的一表面可以为花纹面。
又一实施例中, 加热元件为非接触式加热元件, 定位元件与压纹元件整合 为压头单元。 压头单元的材料为与第二锡层具有小表面张力的材料。 压头单元 包含起伏表面, 起伏表面的起伏高度等于悍带的图案的起伏高度。
本发明的另一态样提供了一种应用图案化悍带的装置的串悍方法, 依序包 含放置悍带于太阳能电池上, 定位元件接触悍带, 下压热压单元以接触悍带使 第二锡层液化并变形, 向上提升热压单元, 牵引第二锡层的高度, 让该第二锡 层由下往上固化形成高低起伏的图案, 以及移除定位元件。 图案的形状决定于 该热压单元上提的速率与高度。

以下将以图式及详细说明清楚说明本发明的精神, 任何本领域技术人员在 了解本发明的较佳实施例后, 当可由本发明所教示的技术, 加以改变及修饰, 其并不脱离本发明的精神与范围。
本发明提出的为一种图案化悍带的装置, 以在悍带表面形成凹凸起伏的图 案, 使得照射到悍带表面的光线经由散射后再反射回太阳能电池表面被利用。 此图案化悍带的装置为整合于串悍的制程之中, 由于串悍工艺可以说是太阳能 电池模块工艺中悍带所受温度最高, 因此,相较于传统使用预先图案化的悍带, 本发明将图案化悍带表面的歩骤整合于现有的串悍工艺中, 可以减少悍带因受 热而使凹凸表面变回平滑表面的情形。 参照图 1, 其绘示本发明的图案化悍带的装置第一实施例的示意图。 图案 化悍带的装置 100为用以图案化悍带 210。 悍带 210具有铜层 214、 第一锡层 212与第二锡层 216,第一锡层 212与第二锡层 216分别位于铜层 214的相对两 表面。 图案化悍带的装置 100包含有定位元件 110、 加热元件 120、 压纹元件 130、 输送带 140以及控制单元 150。 定位元件 110、 加热元件 120以及压纹元 件 130分别为独立元件。控制单元 150与输送带 140、 定位元件 110、加热元件 120与压纹元件 130电性连接,以控制输送带 140、定位元件 110、加热元件 120 与压纹元件 130。
太阳能电池 200与悍带 210为放置在设置于输送带 140上方, 并相对于输 送带 140上下移动。定位元件 110用以定位悍带 210于太阳能电池 200的表面, 此时第一锡层 212接触太阳能电池 200, 且定位元件 110接触悍带 210的表面 可以为平面或是花纹面, 于本实施例中系以具有花纹面为例。 加热元件 120设 置于输送带 140上方。 加热元件 120为非接触式的加热元件, 如热风式或是红 外线式的加热元件, 以加热悍带 210, 使得第一锡层 212与第二锡层 216液化。 悍带 210的第一锡层 212会与太阳能电池 200接触, 例如是与太阳能电池 200 上的银胶层接触, 由于第一锡层 212 与银胶层之间的表面张力极大 (活化能极 大:), 借此将悍带 210串悍于太阳能电池 200。
压纹元件 130设置于输送带 140上方, 并相对于输送带 140上下移动。 压 纹元件 130具有起伏表面 132, 用以接触液化的第二锡层 216, 以在第二锡层 216的表面形成图案。 起伏表面 132的花纹可以为规则或是不规则的花纹。 其 中第一锡层 212与太阳能电池 200之间的表面张力需要大于第二锡层 216与压 纹元件 130之间的表面张力, 以确保悍带 210与太阳能电池 200接合。 举例来 说, 压纹元件 130的材料可以为如表面处理后的耐高温金属或者高分子塑料材 料, 如铁氟龙 CTeflon;)等, 避免已定形的锡面与压纹元件 130结合, 无法分开。 太阳能电池 200的表面可以选择性地布有助悍剂, 以增加太阳能电池 200与悍 带 210之间的活化能。虽然本实施例中以输送带 140进行说明,但是输送带 140 可以替换为如传送滚轮等其它类型的输送平台。
参照图 2A至图 2F, 其分别绘示应用图 1中的图案化悍带的装置的串悍方 法于不同阶段的局部侧视图。
图 2A中, 放置有太阳能电池 200的输送带 140移动至定位, 接着, 放置 悍带 210于太阳能电池 200上,此时第一锡层 212接触太阳能电池 200的表面。 由于在放置悍带 210于太阳能电池 200的时候,悍带 210的表面仍为平滑表面, 故可以直接应用于现有的串悍机台, 不易出现悍带 210吸放时真空吸附异常的 状况。
接着, 图 2B为定位元件 110下压以接触悍带 210,将悍带 210固定于太阳 能电池 200的表面。
接着, 图 2C为加热元件 120加热悍带 210, 使得悍带 210上的第一锡层 212与第二锡层 216液化。 加热元件 120为如热风式或是红外线式的非接触式 加热元件。
接着, 图 2D为下压压纹元件 130, 使得压纹元件 130接触悍带 210, 而在 液化的第二锡层 216上形成与压纹元件 130的起伏表面 132对应的图案。 若是 定位元件 110的表面为花纹面, 则第二锡层 216上亦会形成有对应于定位元件 110的图案。
接着, 图 2E为移除加热元件 120, 使得第一锡层 212与第二锡层 216冷却 与固化, 进而使得第二锡层 216上的图案定型。
最后, 图 2F为移除压纹元件 130与定位元件 110。压纹元件 130具有起伏 表面 132,起伏表面 132的起伏高度 hi等于悍带 210的图案 220的起伏高度 h2, 换言之, 悍带 210上的图案 220为完全对应于压纹元件 130的起伏表面 132。
其中要进一歩说明的是, 待加热元件 120移除后, 并等待悍带 210的图案 220固定后, 压纹元件 130才会自悍带 210上移开, 使得图案 220保留在悍带 210的表面。 压纹元件 130的材料较佳地为与第二锡层 216具有较小表面张力 的耐高温金属或是高分子材料。
若是太阳能电池 200为背面亦需要受光的类型, 则前述装置与方法亦可应 用在位于太阳能电池 200背面的悍带 210, 举例来说, 可以使用表面具有花纹 的输送带 140, 位于太阳能电池 200背面的悍带 210液化接触具有花纹的输送 带, 便可以在悍带 210表面形成有对应的花纹。
参照图 3, 其绘示本发明的图案化悍带的装置第二实施例的示意图。 图案 化悍带的装置 300为用以在串悍工艺中在悍带 210的表面形成图案, 包含有加 热元件 310、 压头单元 320、 输送带 330与控制单元 340。 加热元件 310为如热 风或是红外线等的非接触式加热元件。 压头单元 320整合了定位元件与压纹元 件的功能, 压头单元 320具有起伏表面 322。 输送带 330表面可以具有花纹或 为平整面。 控制单元 340与加热元件 310、 压头单元 320和输送带 330电性连 接, 以控制加热元件 310、 压头单元 320和输送带 330。
参照图 4A至图 4E, 其分别绘示应用图 3中的图案化悍带的装置的串悍方 法于不同阶段的局部侧视图。
图 4A中, 放置有太阳能电池 200的输送带 330移动至定位, 接着, 放置 悍带 210于太阳能电池 200上。此时第一锡层 212接触太阳能电池 200的表面。 由于在放置悍带 210于太阳能电池 200的时候,悍带 210的表面仍为平滑表面, 故可以直接应用于现有的串悍机台, 不易出现真空吸附异常的状况。
图 4B为下压压头单元 320,使压头单元 320接触悍带 210,以定位悍带 210 于太阳能电池 200上。
接着, 图 4C为加热元件 310加热悍带 210, 使得悍带 210上的第一锡层 212与第二锡层 216液化。 加热元件 310为如热风式或是红外线式的非接触式 加热元件。 具有起伏表面 322的压头单元 320会接触液化的第二锡层 216, 使 得第二锡层 216对应于起伏表面 322变形。
接着, 图 4D为移除加热元件 310,使得第一锡层 212与第二锡层 216冷却 与固化, 进而使得第二锡层 216上的图案定型。
最后, 图 4E为移除压头单元 320。 压头单元 320具有起伏表面 322, 起伏 表面 322的起伏高度 h3等于悍带 210的图案 220的起伏高度 h4, 换言之, 悍 带 210上的图案 220为完全对应于压头单元 320的起伏表面 322。
压头单元 320为待加热元件 310移除后, 悍带 210的图案 220固定后才移 开, 使得图案 220保留在悍带 210的表面。 压头单元 320的材料较佳地与第二 锡层 216 具有较小表面张力的材料, 如表面处理后的耐高温金属, 或者高分子 塑料材料, 如铁氟龙 (Teflon)等, 避免已定形的悍带 210的锡面与压头单元 320 结合, 无法分开。
若是太阳能电池 200为背面亦需要受光的类型, 则前述装置与方法亦可应 用在位于太阳能电池 200背面的悍带 210, 举例来说, 可以使用表面具有花纹 的输送带 330, 位于太阳能电池 200背面的悍带 210液化接触具有花纹的输送 带 330, 便可以在悍带 210表面形成有对应的花纹。
相较于仅使用定位元件进行定位, 本实施例中的压头单元 320与悍带 210 之间具有较大的接触面积, 故可以有效分散应力, 避免过去因为定位元件高低 不均而造成串悍时破片的情形。
参照图 5, 其绘示本发明的图案化悍带的装置第三实施例的示意图。 图案 化悍带的装置 400包含有热压单元 410、定位元件 420、输送带 430与控制单元 440。热压单元 410为压纹元件与加热元件的整合单元,热压单元 410为接触悍 带 210以对悍带 210加热, 热压单元 410具有起伏表面 412。 输送带 430的表 面可具有花纹或为平整面。 控制单元 440与热压单元 410、 定位元件 420与输 送带 430电性连接, 以控制热压单元 410、 定位元件 420与输送带 430。
由于热压单元 410采用接触式的加热方式, 本实施例是在加热的同时使得 第二锡层 216变形, 而后在将热压单元 410移离开悍带 210的同时, 使得第二 锡层 216降温固化, 而形成图案。 因此, 热压单元 410的热压头的材料较佳地 为与悍带 210具有较小表面张力的材料, 如常用于烙铁头的金属、 铜、 铁、 陶 瓷材料、 表面处理后的金属、 电镀耐氧化的特殊金属等, 以藉由表面张力的作 用, 牵引第二锡层 216中的悍锡上升。
参照图 6A至图 6F, 其分别绘示应用图 5中的图案化悍带的装置的串悍方 法于不同阶段的沿线段 A-A的局部剖面图。
图 6A中, 放置有太阳能电池 200的输送带 430移动至定位, 接着, 为放 置悍带 210于太阳能电池 200上, 此时第一锡层 212接触太阳能电池 200的表 面。 由于在放置悍带 210于太阳能电池 200的时候, 悍带 210的表面仍为平滑 表面, 故可以直接应用于现有的串悍机台, 不易出现真空吸附异常的状况。
图 6B为定位元件 420接触悍带 210, 以将悍带 210定位于太阳能电池 200 表面。
图 6C为下压热压单元 410, 热压单元 410接触悍带 210加热, 使得悍带 210的第一锡层 212与第二锡层 216液化, 其中热压单元 410接触液化的第二 锡层 216。 热压单元 410的下压深度可以经过设计, 使得液化的第二锡层 216 不会过多的进入起伏表面 412的空隙中。
接着, 图 6D为上提热压单元 410。 由于热压单元 410的材料为与悍带 210 的第二锡层 216具有较大表面张力的材料, 因此, 在向上提升热压单元 410的 过程中, 会一并牵引第二锡层 216的高度, 让第二锡层 216由下往上形成高低 起伏的图案。 接着, 图 6E为热压单元 410完全离开悍带 210表面。 第二锡层 216则是 在热压单元 410上提至离开的过程中渐渐地冷却并固化, 以定形第二锡层 216 上的图案 220'。 图案 220'的形状决定于热压单元 410上提的速率与高度。 换言 之, 藉由调整热压单元 410上提的速率以及拉升的高度, 可以改变悍带 210的 图案 220'的形状。 由于图案 220'是在热压单元 410上提的过程中定型, 因此, 图案 220'的起伏高度 h6会大于热压单元 410的起伏表面 412的起伏高度 h5, 图案 220'的形状不会完全对应于热压单元 410的起伏表面 412的形状。
最后, 图 6F为移除定位元件 420。
参照图 7, 其绘示本发明的一种太阳能电池模块一实施例的示意图。 太阳 能电池模块 500包含有多个太阳能电池 510以及连接太阳能电池 510的至少一 悍带 520。 悍带 520具有一图案化表面, 图案化表面包含至少一第一图案区段 522与至少一第二图案区段 524,其中第一图案区段 522可以由前述的压纹元件 130、压头单元 320或是热压单元 410形成,第二图案区段 524可以是因为前述 的定位元件 110、 420下压所造成的痕迹。第二图案区段 524的面积小于第一图 案区段 522的面积, 第一图案区段 522与第二图案区段 524的图案花纹可以是 相同或是不同。 第一图案区段 522与第二图案区段 524之间具有一间隙, 换言 之, 第一图案区段 522与第二图案区段 524之间为不连续地。 位于太阳能电池 510背面的悍带 520也可视需求形成有第一图案区段 522与第二图案区段 524, 或是直接利用输送带上固有的花纹形成图案。
由上述本发明较佳实施例可知, 应用本发明具有下列优点。 利用图案化悍 带的装置在悍带表面上形成起伏图案, 可以使得照射到悍带上的光线经由散射 与反射传送至太阳能电池而被再一次利用, 以提升太阳能电池的发电效率。 此 图案化悍带的歩骤可以在串悍的过程中或之后完成, 因此, 有效解决使用预先 形成图案的悍带容易因串悍时的高温而使图案变形的问题。 除此之外, 图案化 悍带的装置可以整合于现有的串悍机台, 不需要使用额外的对位系统。 工业应用性
