隨著太陽光電池發電系統發展及廣泛應用，其發電效率是最重要的探討之一，太陽光電系統的電力產生量，幾乎是與太陽能電池的面積以及在太陽光電池表面的太陽輻射能量成正比，也與太陽能電池的溫度有關。來自太陽的輻射能量，除了被太陽能電池轉換成電能，其餘的能量轉換成為熱能，會讓太陽能電池的溫度上升，溫度會高於週遭的氣溫。溫度 對太陽能電池效率的影響大約是溫度每升高1°C時，效率約下降0.4%。若此，溫度增加50°C 時，10%的效率會下降至6%。
本研究透過基本假設與統御方程式加以解析，並且利用ANSYS Fluent有限數值分析軟體進行分析。研究中參照BIPV為基礎，設計一個散熱系統，為了簡化模擬，模擬中只包含二片玻璃板為基礎來進行模擬，二個玻璃板之間裝置Showerhead及玻璃板上方加人三個通風球，本散熱系統中設計四種不同形狀的Showerhead，並探討在各個不同Showerhead的狀態下，受到各種不同日照下及不同風速下，散熱系統的均勻度及溫度分布情形。最後將於整個散熱系統進行加工實體化，經由比對驗証實驗的結果與模擬分析的結果，証實本文所建立的散熱系統對散熱及均勻性有相當不錯的準確度。

Along with the solar power generation system development and the widespread application, the solar power generation system is one of the most important and debated topic in the world. The electricity level which is generated from the solar power system has a positive relationship with the surface scope of the solar battery and the solar radiation energy on the surface of solar battery. Also, it’s related to the temperature of the solar battery itself. Except for being turned into the electricity power, the left-over of the radiation energy, which emitted by the sun and it converted into heat afterwards. The heat is the result after the solar battery’s temperature has increase. Moreover, this temperature is usually higher than the atmospheric temperature. Once the temperature increase for 1°C , it may cause the efficiency of the solar battery to decrease about 0.4% than usual. Furthermore, the efficiency of solar battery will diminish from 10% to 6% while the temperature increasing for 50°C.
Aside from the basic hypotheses and governing equations, this research will also use ANSYS Fluent Finite Element software to assay. Based on BIPV research, in order to simplify the simulation, the simulation has to contain two glasses base for the cooling system. The cooling system was added with the showerhead between two glasses and the three ventilation balls at the top of the two glasses. The cooling system designs four different shapes of showerhead for the simulation. Under each different showerhead condition, received different kind of temperature, various amount of sunlight and wind, the entire cooling system analysis final results have confirmed that the cooling system have the good quality accuracy to the radiation and the uniformity.
