Abstract
Description
本發明係關於一種側聚光式太陽能電池系統，特別是關於一種具有複數個V-型溝槽之側聚光式太陽能電池系統。 The present invention relates to a side concentrating solar cell system, and more particularly to a side concentrating solar cell system having a plurality of V-shaped trenches.
隨著社會的現代化，人們對能源的需求度日益攀升。然而，目前能源來源多半為化石燃料，例如煤、石油、天然氣等，正面臨著蘊藏量有限的問題。並且，化石燃料燃燒過程產生的廢氣，如二氧化碳、硫化物等，不僅造成空氣汙染、也助長溫室效應，間接影響氣候變遷。因此，尋找替代能源乃勢在必行。各種新能源技術中，太陽能電池因有能源來源取之不盡、能源轉換無汙染、裝置可模組化、能源取得無地域性等多項優點，近年倍受注目。 With the modernization of society, people's demand for energy is rising. However, most of the current energy sources are fossil fuels, such as coal, oil, natural gas, etc., which are facing limited problems. Moreover, the waste gas generated by the burning process of fossil fuels, such as carbon dioxide and sulfides, not only causes air pollution, but also contributes to the greenhouse effect and indirectly affects climate change. Therefore, it is imperative to find alternative energy sources. Among various new energy technologies, solar cells have attracted much attention in recent years due to their inexhaustible sources of energy, pollution-free energy conversion, modularization of devices, and non-regional energy.
太陽能電池雖有上述多項優勢，但目前尚未主導能源市場，主要是因電池轉換效率仍待提升，且電池、系統成本仍高。聚光型太陽能電池系統是一種改良式的太陽能電池系統，其藉由聚光元件，將入光面接受到的太陽光會聚到面積較小的電池吸收面上；如此，可節省太陽能電池材料的用量，而降低太陽能電池系統的成本。但傳統聚光型太陽能電池系統之電池位於聚光元件之下方，系統體積須包含聚光所需之焦距，這使得系統厚度 增大；且電池須位於焦點光斑範圍內，當聚光倍率高時，組裝對位難度提高，以致製作工序的複雜度提升。這些因素也造成傳統聚光型太陽能電池系統的應用普及性降低。為減小系統體積，Karp等人於2010年之Optics Express提出太陽能電池位於聚光元件側面的側聚光式架構。其聚光元件包含一微透鏡陣列及一導光板；微透鏡陣列用以會聚光線至導光板上的反射器，導光板用以將光線導至位於側面的太陽能電池。然而，此架構的二光學元件需有高度精準之對位，以減少光線由透鏡耦合至導光板時的能量損失(coupling loss)。因此，雖體積減小，但組裝難度並未降低。 Although solar cells have many of the above advantages, they have not yet dominated the energy market, mainly because battery conversion efficiency still needs to be improved, and battery and system costs are still high. The concentrating solar cell system is an improved solar cell system, which converges the sunlight received by the light incident surface onto the absorption surface of the smaller cell by means of the concentrating element; thus, the amount of the solar cell material can be saved. And reduce the cost of solar cell systems. However, the battery of the conventional concentrating solar cell system is located below the concentrating element, and the system volume must contain the focal length required for concentrating, which makes the system thickness Increased; and the battery must be in the range of the focus spot. When the concentrating magnification is high, the difficulty of assembling the alignment is increased, so that the complexity of the manufacturing process is improved. These factors also contribute to the reduced popularity of conventional concentrating solar cell systems. In order to reduce the size of the system, Karp et al. in 2010, Optics Express proposed a side-lighting architecture in which the solar cells are located on the side of the concentrating element. The concentrating element comprises a microlens array and a light guide plate; the microlens array is used to condense light onto a reflector on the light guide plate, and the light guide plate is used to guide the light to the solar cells on the side. However, the two optics of this architecture require a highly accurate alignment to reduce the coupling loss of light when coupled to the light guide by the lens. Therefore, although the volume is reduced, the assembly difficulty is not reduced.
綜上所述，在大幅提高應用普及性的前提下，如何提供一個高信賴性、高穩定性、整體體積大幅減小，且有效降低製作工序複雜度的聚光型太陽能電池系統，便迫切地亟待研發。 In summary, under the premise of greatly improving the popularity of the application, how to provide a concentrating solar cell system with high reliability, high stability, large overall volume reduction, and effective reduction of the complexity of the manufacturing process is urgently Need to be developed.
