摘要:	本計畫研發平面型之側聚光太陽能系統以應用於窗式建材，使住商建築之窗戶不僅具通風及自然照明功能，更帶來創能效益；其所會集之太陽光，除可轉換為電能，亦可轉為熱能，供建築彈性使用太陽能源。計畫第一年將進行側聚光型光電單葉窗之設計、製作與驗證，以最佳化單葉片時之光電轉換效率。第二年則將第一年所優化之單葉窗陣列化，以完成側聚光型光電百葉窗雛型；而為了提高太陽能電池效能，將於太陽能電池之背面連接集熱裝置，使電池晶片的廢熱適當導出，並實現側聚光型導熱光電百葉窗。第三年則進一步改良側聚光元件，使得紅外波段與非紅外波段分別由不同輸出端導出，紅外波段之輸出端連接集熱裝置以匯集熱能，非紅外波段之輸出端則連接太陽能電池以發電，達到同時產電與集熱之側聚光型熱電共生百葉窗。本計畫研發之側聚光型百葉窗，其產生之電能除可直接供能予家用，亦可與儲電元件結合；所會聚之熱能則可導引至建築內之熱應用，如太陽能熱水、吸附式冷氣等。故此系統之研發，有助於實現窗式創能系統。且因系統產出之能源將直接應用建築內民生需求，因此無需併網成本；另一效益則是有助於住商減少對傳統燃煤、燃氣發電之依賴，故亦將對空汙及PM2.5等問題之改善有所貢獻。 ;The project develops a side-absorption concentrated solar system for window applications. The proposed system enables the residential windows not only to have the functions of ventilation and natural lighting but also to bring about the benefit of energy creation. The collected sunlight can be converted into the electricity as well as the heat energy for arbitrary applications. In the first year of the project, the design, fabrication and verification of a side-absorption concentrated photovoltaic louver (SCPL) with a single leaf will be conducted to optimize the photoelectric conversion efficiency. In the second year, the single-leaf SCPL will be arrayed to form a SCPL with multiple leaves. Moreover, in order to improve solar cell efficiency, the back side of the solar cell will be connected to a heat-collector, so that the waste heat of solar cell is properly collected, and an side-absorption concentrated photovoltaic/thermal (PV/T) louver can be realized. In the third year, the concentrated optics is further improved, so that the infrared and the non-infrared spectra will be derived from different output ports. The output port of the infrared spectrum is connected with the heat collector, while the output end of the non-infrared spectrum is connected with the solar cell. Thus, the proposed system can produce electricity and heat at the same time and forms another side-absorption concentrated (PV/T) louver for the efficient co-generation of photovoltaic/thermal energy. In addition, the proposed side-absorption concentrated solar system generates the electricity which can directly supply to household appliances and to energy-storage elements, while the collected heat energy can be used to the thermal applications, such as water heating, adsorption air-conditioner, and so on, inside the building. Therefore, the research and development of the proposed system helps to achieve a window type of energy-creation system. Since the generated energy will directly apply to the energy demands inside the building, so there is no need for grid connection and the connection costs. Another benefit of the proposed system is to help residents to reduce the reliance on traditional coal-fired and gas-fired power generation. Thus, the proposed system contributes to reducing the air pollution and resolving the PM2.5 issue.
