[0012] 在此描述的实施例包括一个光伏(PV)装置,其使用光学元件和PV元件的特定构造将光转换成电能。 [0012] Example embodiments described herein includes a photovoltaic (PV) devices, which uses the optical element and the specific configuration of the PV elements convert light to electrical energy. 例如,一个这样的PV装置可以包含一个聚光器(light concentrator)阵列以收集和聚焦光,以及一个分光器(Iightsplitter)以选择性地反射和透射被收集和被聚焦的光。 For example, one such means may comprise a PV concentrator (light concentrator) to collect and focus light array, and a beam splitter (Iightsplitter) to selectively reflected and transmitted light is collected and focused. 这种选择性可以是至少部分是取决于被收集光的波长。 This selectivity may be at least partially dependent on the wavelength of light being collected. 具体地,一组独立分光器阵列可以反射具有特定波长范围的光,并引导这些反射光到第一太阳能电池。 In particular, a group of independent beam splitter array may reflect light having a specific wavelength range, and guide the reflected light to the first solar cell. 另一组特定波长范围的光可以穿透分光器阵列,分光器阵列并引导这些透射光到一个或多个第二太阳能电池。 Another group of light of a specific wavelength range can penetrate the beamsplitter arrays, arrays and directing the beam splitter transmits light to a second or more solar cells. 这种分光器阵列可以被设置以引导这些反射光会聚到与第一太阳能电池位置一致的区域。 This beamsplitter array may be arranged to direct the reflected light onto a first solar cell with the same location area. 例如,该位置距离聚光器阵列的每个元件有相等的距离。 For example, the position of an equal distance from each element of the array of optical concentrators. 第一和第二太阳能电池可以有互相不同的工作波长范围。 The first and second solar cells may have a different range of operating wavelengths from each other. 这种PV装置可以有许多优点。 This PV device may have many advantages. 例如,特定的PV元件,其后称为太阳能电池,仅在特定波长范围上有效地运行。 For example, a particular PV elements, thereafter referred to as solar cells, function effectively only in a specific wavelength range. 换言之,不同的太阳能电池在不同波长范围上会有不同效能。 In other words, the different solar cells have different performance on different wavelength ranges. 例如,一种双结(double-junction) (DJ)太阳能电池能够在一个880nm到1270nm的波长范围内有最高的转换效能,而一个娃基太阳能电池能够在一个310nm到880nm的波长范围内最有最高的转换效能,尽管本发明主题并不受限于此方面。 For example, a dual junction (double-junction) (DJ) of the solar cell to have the highest conversion efficiency in a wavelength range of 880nm to 1270nm, and the solar cell can be a baby group in a 310nm to 880nm wavelength range is most the highest conversion efficiency, although the subject of the present invention is not limited in this respect. 由于太阳光包括一个相当广带宽的波长,利用多种类型的太阳能电池以将多种波长范围的光转换成电能是有利的。 Since sunlight includes a very wide wavelength bandwidth, using various types of solar cells to convert the plurality of wavelength range into electrical energy it is advantageous. 因此,如上所述的PV装置的一个实施例,能够容纳不止一种类型的太阳能电池,从而提高PV装置的运行波长范围。 Thus, a PV device embodiments described above, it is possible to accommodate more than one type of solar cell, thereby improving the operating wavelength range of the PV device.

[0013] 这种PV装置带来的另一个优点是PV装置的紧凑性,这可以通过特定光元件和/或这种光元件的特定结构来实现,这将在以下详细描述。 [0013] Another advantage of such a PV device is brought compactness of the PV device, which can be achieved by the particular light element and / or a specific structure of such an optical element, which will be described in detail below. 另一个优点可以是:这种PV装置可以使用相当小的光元件来运行,这与大尺寸光器件相比,要便宜得多。 Another advantage may be that: This PV device may use relatively small optical element run, which compared with large-size optical device, much cheaper. 还有另外一个优点:通过PV装置的一个结构元件(如热管)可以从PV装置有效地去除在运行特定类型的太阳能电池过程中所产生的热,这将在以下详细描述。 There is another advantage: the heat can be effectively removed in the operation of a particular type solar cell produced by the process from the PV device by a structural element (e.g., heat pipes) PV devices, which will be described in detail hereinafter. 在此情况下,PV装置不需要包含专用的散热部件。 In this case, PV device need not include a dedicated heat member. 因此,这种PV装置可以有许多优点,一个相当高效的、小尺寸的低成本的太阳能产生装置。 Thus, such a PV device may have many advantages, a quite efficient, low-cost solar generation apparatus small-sized. 当然,这种PV装置的优点不限于上述优点,并且本发明主题也不受此限制。 Of course, this advantage is not limited to the above-described PV device advantages and subject of the present invention is not so limited.

[0014] 在一个实施例里,一种制作PV装置如上述实施例的PV装置的方法,包括:组装一组聚光器阵列以收集和/或聚焦光,如太阳光。 [0014] In one embodiment, the method of PV PV installation apparatus of the above embodiment of the method of making, comprising: assembling a set of array concentrator to collect and / or focus light, such as sunlight. 为了与这种集光器结合运行,可以配置一组独立分光器阵列以便至少部分是根据光的波长而选择性地反射和透射被收集和/或被聚焦的光。 In order to operate in conjunction with such collector, a separate set may be configured to at least partially beamsplitter array is selectively reflected and transmitted light is collected and / or focusing the light according to the wavelength. 该分光器阵列可以被设置以引导反射光到第一太阳能电池,并引导透射光到一个或多个第二太阳能电池。 The beamsplitter array can be provided to direct reflected light into the first solar cell and directing the transmitted light to one or more of the second solar cell. 第一和第二太阳能电池可以有互相不同的工作波长范围。 The first and second solar cells may have a different range of operating wavelengths from each other. 另外,反射光可以通过聚光器和分光器的组合被准直,以会聚到一个与第一太阳能电池位置一致的区域。 Further, the reflected light may be collimated by a combination of beam splitter and the condenser, to converge into a first solar cell with the same location area. 在一个实施里,一个或多个第二太阳能电池可以安置在聚光器阵列和分光器阵列的一个中央轴附近。 In one embodiment, the one or more second solar cells may be arranged in the vicinity of a central axis of the array and the beam concentrator array. 例如,可以是以中央轴中心对称地安置。 For example, the central axis is symmetrically disposed.

[0015] 在一个实施例里,一种PV装置如上述实施例的PV装置的运行方法,可以包括:收集和/或聚焦入射光,提供被收集和/或被聚焦的光到一组分光器阵列。 [0015] In one embodiment, in a method of operating apparatus PV PV device of the above embodiment, may include: collecting and / or focusing incident light, providing light to the optical component is a collecting and / or focusing arrays. 这组独立个分光器阵列可以至少部分地是选择性地根据光的波长把光反射,并至少部分地根据所述光的所述波长透射被收集的光。 This group is independently a beamsplitter array can be at least partially reflect light selectively according to wavelength of light, and at least partially transmitting the collected light according to the wavelength of the light. 接着,反射光可以被引导以会聚到一个与第一太阳能电池位置一致的区域,而透射光可以被引导到一个或多个第二太阳能电池。 Subsequently, the reflected light can be directed to converge into a first solar cell with the same location area, and the transmitted light may be directed to one or more of the second solar cell. 第一和第二太阳能电池可以有互相不同的工作波长范围。 The first and second solar cells may have a different range of operating wavelengths from each other. 当然,制作或运行一个PV装置的这些细节仅是范例,而本发明主题并不受此限制。 Of course, these details or operation of making a PV device are merely examples, and the subject of the present invention is not so limited.

[0016] 图1是一个实施例的光伏装置100的示意图。 [0016] FIG. 1 is a schematic of a photovoltaic device 100 of the embodiment. 光105落在聚光器120的阵列110上时,可以被聚焦和被引导到一组分光器阵列130上。 Light 105 falls on the array 110 when the concentrator 120, can be focused and directed onto an array of optical component 130. 这组聚光器可以包括折射透镜或一个折射透镜组合(如组合透镜),和/或菲涅尔(Fresnel)透镜,这仅仅是一些例子。 This may include a set of converging lens or a refractive lens refractive compositions (e.g., combined lens), and / or Fresnel (the Fresnel) lens, which are just a few examples. 这组聚光器可以有一个相关的焦距,其确定穿过聚光器的光可以被聚焦的距离。 This group may have an associated condenser focal length, which determines the distance of the light passing through the condenser can be focused. 另外,这个聚光器可以有一个相关的数值孔径(NA),其确定穿过聚光器的光的会聚角度。 Further, the condenser may have an associated numerical aperture (NA), which determines the angle of convergence of the light passing through the concentrator. 因此,这个聚光器可以将光以一个特定角度会聚并聚焦到一个特定焦距上。 Therefore, the concentrator may be converged and focused light to a specific focal length at a specific angle. 例如,这个聚光器的光元件下游可以根据该聚光器的焦距和/或NA来安置。 For example, downstream of the condenser optical element may be disposed according to the focal length of the condenser and / or NA. 这个聚光器的一个阵列可以包括一个或多个聚光器以任何可能的方式来安排。 An array of the condenser may include one or more condenser to be arranged in any possible way. 在一个特定例子里,这个阵列可以包括以行列排列的的四个聚光器,这将在以下详细描述。 In one particular case, the array may include four condenser arranged in rows and columns, which will be described in detail below. 相对使用单个大型聚光器元件,使用相对较小聚光器的一个阵列能够有效地降低PV装置100的成本。 Opposed to a single large condenser element, a relatively small array of a concentrator is possible to effectively reduce the cost of the PV device 100.

[0017] 在一个实施里,分光器130可以包括一个光元件,其会反射具有特定波长范围的光,同时会透射具有另一个特定波长范围的光。 [0017] In one embodiment, the beam splitter 130 may include an optical element, which will reflect light having a specific wavelength range, while another particular wavelength range of light transmission will have. 这个分光器可以包括一个光学窗(如石英),其包括在光学窗一个或两个侧面上的多个光介质涂层。 The optical splitter may comprise a window (such as quartz), which comprises a plurality of optical dielectric coating on both sides of a window or optical. 这个光学窗不一定是平坦表面。 The optical window is not necessarily a flat surface. 涂层可以至少部分地根据入射光的波长反射和/或透射入射光。 The coating may at least partially reflects incident light wavelength and / or transmit incident light according to. 在一个特定实施里,PV装置100可以为每个分光器而包括一个聚光器。 In one particular embodiment where, PV device 100 may comprise a beam splitter for each of the concentrator. 在此情况下,聚光器120所收集的入射光105可以引导会聚光到一个对应的分光器130。 In this case, the condenser 120 is collected by the incident light 105 may be directed into a convergent light beam splitter 130 corresponds. 接着,分光器130可以反射一部分光到第一太阳能电池160,并透射另一部分光到第二太阳能电池140。 Subsequently, a portion of the beam splitter 130 may reflect the light to the first solar cell 160, and transmits the light to another portion of the second solar cell 140. 如上所述,这些部分光可以由光的波长来确定。 As described above, these portions may be determined by the light wavelength of the light. 而且,一个或多个反射镜可以放置在分光器130和第一和/或第二太阳能电池之间,以便能够引导光到太阳能电池上。 Also, one or more mirrors may be placed between beam splitter 130 and the first and / or second solar cell, so that the light can be guided to the solar cell. 在PV装置100里,例如,反射镜150可以放置在第一太阳能电池160的前面。 In the PV device 100, e.g., mirror 150 may be placed in front of the first solar cell 160. 当然,PV装置的这些方面和细节仅是范例,本发明主题并不受此限制。 Of course, aspects and details of these are merely examples of the PV device, subject of the present invention is not so limited.

[0018] 图2包括一个实施例的光伏系统200的结构侧视图和示意图。 [0018] FIG. 2 includes a side view and a schematic structure of a photovoltaic system 200 of the embodiment. 聚光器220的阵列210可以收集入射光272,入射光不需要一定是垂直入射到聚光器220的表面上,如图2所示。 220 concentrator array 210 can collect incident light 272, incident light need not necessarily be vertically incident on the surface of the condenser 220, as shown in FIG. 从聚光器220出来(即透射出)的光274可以落在分光器230上,其可以沿中央轴205对称分布。 Out from the condenser 220 (i.e., a transmission) 274 light may fall on the beam splitter 230, which may be distributed along the central axis 205 of symmetry. 聚光器220也可以沿中央轴205对称分布。 Condenser 220 may also be distributed along the central axis 205 of symmetry. 在一个实施里,中央轴205可以与聚光器220的一个中央点和分光器230的一个中央点相交。 In one embodiment, the central axis 205 may intersect the center point of a center point of a beam splitter 230 and the condenser 220. 分光器230可以反射具有特定波长范围的一部分光274。 Beam splitter 230 may reflect a portion of light having a specific wavelength range of 274. 例如,光可以从相对中央轴205以一个角度285倾斜的分光器被反射,反射光276可以通过反射镜250被引导到第一太阳能电池260。 For example, light may be reflected from opposite the central axis 205 is inclined at an angle of beam splitter 285, reflected light 276 may be directed to the first solar cell 260 through the mirror 250. 在这个实施里,调整倾斜角度285能够将多个光束(丛各个分光器230反射的光)聚焦到第一太阳能电池260上,方法简单。 In this embodiment, the inclination angle 285 can be adjusted to a plurality of light beams (each bundle of light reflected by the beam splitter 230) is focused onto a first solar cell 260, the method is simple. 为了叙述一个特定的例子,最好的倾斜角度285大约为66度,在这个角度上,落在第一太阳能电池260上的光斑形状和尺寸可以被调整以增强PV装置200的光准直。 To describe a specific example, the inclination angle 285 is preferably about 66 degrees, at this point, the spot falls on the shape and size of the first solar cell 260 may be adjusted to enhance light collimation apparatus 200 of PV. 特别地,各个分光器可以以角度285倾斜,角度285可以包括一个与中央轴成60度到70度之间的范围。 In particular, each beam splitter 285 may be inclined at an angle, the angle 285 may comprise a central axis in a range between 60 degrees to 70 degrees. 当分光器230的倾斜角度偏差于此倾斜角度的范围可能误导光276,导致只有相当少部分的光276能被引导到第一太阳能电池260的位置上。 When the inclination angle of the beam splitter 230 this range of variation of the inclination angle of light 276 may be misleading, resulting in only a relatively small portion of the light 276 can be guided to a position 260 of the first solar cell. 光278表示从反射镜250反射到到第一太阳能电池260的光。 Light 278 represents light reflected from the mirror 250 to the solar cell 260 to the first. 因此,分光器230的角度调整可以提供一种技术用于调整PV装置200的工作效能。 Thus, the angle adjusting beam splitter 230 may provide a technique for adjusting the work efficiency PV device 200. 当然,对涉及具有不同于上述例子的焦距的光元件(如聚光器)的实施而言,在角度285上实现期望的光准直可能也是不同的。 Of course, for embodiments relates to an optical element (e.g., a condenser) having a focal length different from that of the above-described example, to achieve a desired angle on the optical collimator 285 may also be different. PV装置200的一个特定特征是如下事实:多个光路径,或如下所述的“通道”,可以被引导以会聚到第一太阳能电池260上,其可能包括单个太阳能电池。 PV device 200 a particular feature is the fact that: a plurality of optical paths, as described below, or "channel" can be directed to converge into a first solar cell 260, which may include a single solar cell. 这种多个光路径会聚在一个相当小区域上(包括第一太阳能电池260)的结果是,在第一太阳能电池260上集中有相当大数量的热量。 Such a plurality of light paths converge on a relatively small area (including a first solar cell 260) of the result, the solar cell 260 in the first set has a considerable amount of heat. 因此,例如,第一太阳能电池260可以安装在一个热管上或靠近热管(如图3-5所示)以从第一太阳能电池260将热传导走。 Thus, for example, the first solar cell 260 may be mounted on or near a heat pipe heat pipe (Figure 3-5) to conduct heat away from the first solar cell 260.

[0019] —部分未被分光器230反射的光274可以被分光器230透射。 [0019] - not part of the light 230 reflected by the beam splitter 274 may be transmitted beam splitter 230. 如上所述,这些透射光282可以是与反射光276拥有的不同波长范围的光。 As described above, the transmitted light 282 can have different wavelength ranges of the reflected light 276. 例如,透射光282可以被引导到第二太阳能电池240。 For example, the transmitted light 282 may be directed to the second solar cell 240. PV装置200的一个特定特征是以下事实:单个第二太阳能电池240可以被配置以接收来自单个光路径的光。 PV device 200 is a particular feature is the fact that: a single second solar cell 240 may be configured to receive light from a single light path. 这种一对一对应的结果是,在第二太阳能电池240上集中的热可以相对平均地分布在多个第二太阳能电池240所占的相对较大的面积上。 This one corresponding result, the heat on the second focus of the solar cell 240 may be relatively evenly distributed over a relatively large area of ​​the second solar cells 240 occupied. 因此,PV装置200能够避免由于太阳能电池过热引起的问题。 Thus, PV device 200 can avoid problems caused by overheating of the solar cell.
