下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 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他实施例， 都属于本发明保护的范围。
本发明实施例提供了一种新型的幕墙， 其可以是玻璃材质的幕墙、 石英 材质的幕墙， 或者其他常用的幕墙材质。 在本发明实施例中， 以玻璃幕墙为 例来对本发明提供的方案迸行介绍。
请参考图 1 , 本发明实施例提供了一种玻璃幕墙， 该玻璃幕墙包括显示 器件 2和太阳能电池板 1， 显示器件 2和太阳能电池板 1叠层设置。
上述玻璃幕墙中， 太阳能电池板 1将自然界中的太阳光转换为电能， 进 而为显示器件 2提供电源， 且， 显示器件 2和太阳能电池板 1叠层设置， 能 够满足玻璃幕墙的厚度需求。
上述玻璃幕墙中，太阳能电池板 1在有太阳光照的情况下可以随时充电， 当显示器件 2在显示时利用由太阳能电池板 1转换太阳能而来的电能， 进而 能够节省能源。
在上述玻璃幕墙的太阳能电池板 1和显示器件 2中， 至少有一个可以是 透明结构。 这样， 太阳能电池板 1 既可以制作在玻璃幕墙朝向室内的一侧， 也可以制作在朝向室外的一侧。
一种优选实施方式中， 上述太阳能电池板 1为透明太阳能电池板， 且显 示器件 2为透明显示器件。 上述太阳能电池板 i为透明太阳能电池板， 显示 器件 2为透明显示器件， 能够使太阳能电池板 1与显示器件 2之间的叠放顺 序有多种选择， 且便于实现玻璃幕墙的双面显示， 且提高玻璃幕墙的透明性 实现玻璃幕墙的透明显示。
太阳能电池板 i为透明太阳能电池板， 显示器件 2为透明显示器件时， 太阳能电池板 I与显示器件 2之间的叠放方式可以有多种。 例如：
方式一： 太阳能电池板 i位于显示器件 2朝向室外的一侧， 且显示器件 2朝向太阳能电池板 1 的一侧为其出光侧， 由于太阳能电池板 1为透明太阳 能电池板， 因此， 太阳能电池板 1不会影响显示器件 2的显示， 玻璃幕墙能 够实现室外显示； 且太阳能电池板 1能够更好地接收太阳能并转换为更多的 电能。
方式二： 太阳能电池板 1位于显示器件 2朝向室外的一侧， 且显示器件 2朝向室内的一侧为其出光侧， 玻璃幕墙能够实现室内显示， 太阳能电池板 1 为透明太阳能电池板， 显示器件 2为透明显示器件， 因此玻璃幕墙的透光性 较高； 另外， 太阳能电池板 1能够接收更多的太阳能并转换为更多的电能。
方式三： 太阳能电池板 1位于显示器件 2朝向室内的一侧， 且显示器件 2朝向室外的一侧为出光侧。
方式四： 太阳能电池板 1位于显示器件 2朝向室内的一侧， 且显示器件 2朝向室内的一侧为出光侧。
当然，在上述四种实施方式中，所述显示器件 2也可以是双面显示器件， 这样不管透明太阳能电池板和透明显示器件的位置如何摆放， 都可以实现室 内和室外的同时显示。
一种优选实施方式中， 具体地， 上述太阳能电池板 1 可以为染料敏化太 阳能电池板。 染料敏化太阳能电池板成本低， 且光电转化效率较高。
请参考图 2、 图 3以及图 4， 图 2为本发明实施例提供的玻璃幕墙中染料 敏化太阳能电池板的一种结构示意图； 图 3为本发明实施例提供的玻璃幕墙 中透明显示器件为 OLED时的一种结构示意图； 图 4为本发明实施例提供的 玻璃幕墙中透明显示器件为液晶显示器件时的一种结构示意图。
如图 2所示， 染料敏化太阳能电池板包括： 第一透明基板 I I、 第一导电 层 12、 对电极 13、 电解质 14、 染料敏化剂 15、 介孔光阳极 16、 第二导电层 17和第二透明基板 18, 其中：
第一透明基板 11和第二透明基板 18可以是透明的玻璃基板或透过率较 高的树脂基板。
第一导电层 12和第二导电层 17为使用透明材料制备的导电层， 上述透 明材料可以是 FTO (Fluorine-doped Tin Oxide, 氟掺杂锡氧化物）、 IT0 (氧 化铟锡）、 碳纳米管、 或石墨烯； 当然， 上述第一导电层 12和第二导电层 17 还可以为由其他材料制备的透明导电层， 这里不再赘述。
对电极 13为由铂金属制备的对电极； 对电极 13可以通过将电极材料通 过热分解、 溅射、 蒸鍍、 印刷或者喷涂等方法制备在导电基底上而形成， 形 成对电极 13的电极材料要求具有良好的导电性能和优越的电化学催化性能。
电解质 14根据其状态的不同分为三种： 液态电解质、准固态电解质和固 态电解质。 最常见的为 Γ\Ι3'·氧化还原对， 现在已开发出不吸收光的氧化还原 对固态电解质， 如 Spiro- OMeTAD, 其是一种透明固态电解质。
染料敏化剂 15 的主要材料有钌金属配合物 （N3、 N7i9)、 有机染料等； 染料敏化剂 15是染料敏化太阳能电池板中产生电子的部分，其作 ^为吸收太 阳光的能量激发出电子， 并将电子注入到介孔光阳极 16 中， 随后被电解质 14还原。 介孔光阳极 16 的制备材料主要有纳米二氧化钛 （Ti02) 和纳米氧化锌 (ZnO) 两种 n型半导体材料。 其中纳米 Ti02颗粒最常见， 制备的染料敏化 太阳能电池板的光电性能较好。介孔光阳极 16在染料敏化太阳能电池板中主 要是作为染料敏化剂 15 的吸^载体、 电子传输通道， 因此， 介孔光阳极 16 应具备尽可能大的比表面积以吸附更多染料敏化剂 15， 提高染料敏化太阳能 电池板的性能； 同时， 介孔光阳极 16 中介孔的孔径应足够大以方便电解质 14在其中的渗透、 扩散。 为了接受染料敏化剂 15注入的电子， 介孔光阳极 16的制备材料的能级必须要与染料敏化剂 15相匹配。
当染料敏化太阳能电池板的面积较大时，通常会在导电层 Π和介孔光阳 极 16之间加金属导线， 以收集电子且降低导电层 17的电阻。 该金属材料可 为 Ag、 Αι Pt等贵金属导线，在非腐蚀性电解质中可以采用 Cu、 A1等金属。
一种优选实施方式中， 在上述太阳能电池板 i为透明太阳能电池板， 显 示器件 2为透明显示器件时， 如图 1所示， 上述玻璃幕墙还包括 3D显示辅 件 201、 触控显示辅件或者 3D显示辅件 201和触控显示辅件的组合； 其中，
3D显示辅件 201设置在显示器件 2的出光侧， 如图 1所示； 或者 3D显 示辅件集成于太阳能电池板 1内部；
上述触控显示辅件设置在玻璃幕墙的出光侧， 或者集成于显示器件 2的 内部。
在上述玻璃幕墙中设置 3D显示辅件时， 玻璃幕墙具备了 3D显示效果， 进而提高了玻璃幕墙的显示效果。
在上述玻璃幕墙中设置蝕控显示辅件时， 能够提高玻璃幕墙的操控性。 当上述玻璃幕墙中的 3D 显示辅件集成在太阳能电池板内部^, 以集成 在染料敏化太阳能电池板内为例， 3D显示辅件可以是由染料敏化太阳能电池 板具有的对电极 13形成的光栅类 3D显示辅件； 或者， 当染料敏化太阳能电 池板的导电层 17与介孔光阳极 16之间设有金属线时， 3D显示辅件还可以由 导电层 17与介孔光阳极 16之间的金属线形成， 金属线的形成规则与光栅类 3D显示辅件的设计规则一致， 以满足 3D显示要求， 从而可在实现同样功能 的情况下筒化玻璃幕墙的结构。
优选地， 上述显示器件 2为可自发光的透明显示器件， 且显示器件 2的 两侧均具有 3D显示辅件或者触控显示辅件。
上述玻璃幕墙中，显示器件 2的两侧均具有 3D显示辅件时，请参考图 5， 透明显示器件 2背离太阳能电池板 1的一侧具有第一 3D显示辅件 2011， 透 明显示器件 2朝向太阳能电池板 1的一侧具有第二 3D显示辅件 2012。这样， 上述玻璃幕墙既可以室内显示 3D图像， 又可以室外显示 3D图像， 可以全方 位地进行信息显示， 进一步提高了上述玻璃幕墙的显示效果。 当然， 显示器 件 2的一侧设有第一 3D显示辅件 2011， 另一侧设置第二 3D显示辅件 2012 时， 可以考虑在对于室内显示时使室内观看者观看到的图像以凹进去的图像 方式迸行显示， 这样会觉得室内空间较大， 观看者观看到的显示画面更加自 然； 而对于室外显示时， 使室外观看者观看到的图像以凸出来的图像方式迸 行显示， 这样室外观看者观看到的立体效果更直观震撼。 上述图像以凹进去 或凸出来的图像方式进行显示， 可以通过调整图像编码来控制， 此处不再赘 述。
除了图 5所示的结构之外， 第一 3D显示辅件 2012也可以设置在太阳能 电池板 1的外侧。
上述玻璃幕墙中， 显示器件 2的两侧均具有触控显示辅件时， 自玻璃幕 墙的两面均可以对显示器件 2进行操控， 迸一步提高玻璃幕墙显示时的操控 性。
一种优选实施方式中， 较佳地， 显示器件 2为可自发光的双向透明显示 器件时， 可以具体为电致发光器件、 或量子点发光器件等。 当然其他自发光 的双向透明显示器件也可以， 这里不再一一举例。
请参考图 6， 优选地， 当上述显示器件 2为液晶显示器件时， 例如液晶 面板， 为保证液晶显示器件能够同 H寸在白天和晚上进行显示， 液晶显示器件 与太阳能电池板 i之间具有光源器件 4， 光源器件 4通电时发光， 不通电时 为透明状态。
上述液晶显示器件在白天进行透明显示时，上述光源器件 4呈透明状态， 液晶显示器件能够利用自然光线迸行显示； 需要上述液晶显示器件在晚上正 常显示时， 给上述光源器件 4遥电， 上述光源器件 4发光为液晶显示器件提 供背光源， 迸而使上述液晶显示器件能够进行正常显示。 有必要说明的是， 上述光源器件 4的电源提供也可以由太阳能电池板 1的蓄电能源进行提供。 具体地， 上述光源器件 4可以为透明无源 OLED器件。
一种优选实施方式中， 为了筒化上述玻璃幕墙的结构， 太阳能电池板 ！ 朝向显示器件 2—侧的透明基板复用为显示器件 2中朝向太阳能电池板 1一 侧的衬底基板。
优选地， 上述显示器件 2为电致发光器件、 量子点发光器件、 或者液晶 显示器件。
如图 3所示， 当上述显示器件 2为电致发光器件 OLED时， 电致发光器 件包括： 玻璃基板 25、 透明阴极 26、 电子传输层 27、 有机发光层 28、 空穴 传输层 29、 透明阳极 20 以及另一个基板。 在本实施例中， 电致发光器件中 的上述另一个基板可以与染料敏化太阳能电池板的透明基板 11复用， 即， 透 明基板 II既作为染料敏化太阳能电池板的一个衬底基板，还作为电致发光器 件的一个衬底基板， 可以筒化玻璃幕墙的结构。 进一步地， 在显示器件 2的 出光侧，即玻璃基板 25外侧可以设置 3D显示辅件 201 ,以实现 3D显示效果。
同理， 如图 4所示， 上述显示器件 2为液晶显示器件时， 上述玻璃幕墙 可以具有下述结构， 包括： 彩膜基板 22、 液晶层 23、 阵列基板 24、 第一透 明基板 11、 第一导电层 12、 对电极 13、 电解质 14、 染料敏化剂 15、 介孔光 阳极 16、 第二导电层 17和第二透明基板 18。 当然， 第一透明基板 11可以与 阵列基板 24使用同一块衬底基板，同样可以简化上述玻璃幕墙的结构。此外, 在显示器件 2的出光面，即彩膜基板 22的外侧还可以设置 3D显示辅件 201 , 以实现 3D显示效果。
一种优选实施方式中， 太阳能电池板 1 的周边设有用于供电用的周边电 路， 上述太阳能电池板 i与显示器件 2之间可以通过下述方式实现太阳能电 池板 1对显示器件 2进行电源供电：
太阳能电池板 I 的周边电路与显示器件 2的电路之间通过柔性电路板电 性连接； 或者太阳能电池板 i的周边电路与显示器件 2的电路之间通过过孔 连接， 所述过孔可以是贯穿太阳能电池板 1和显示器件 2间相贴附的两块透 明基板， 也可以是贯穿太阳能电池板 1和显示器件 2复用的透明基板。
显然， 本领域的技术人员可以对本发明实施例进行各种改动和变型而不 脱离本发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明 权利要求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在 内。
