本研究將先由聯相光電5F BIPV(Building-Integrated Photovoltaic)外牆為實驗基礎，針對Insulating Glass模組進行溫度預測，並且把模擬結果與實驗進行比對，然後模擬在不同風速及日照量底下模組的溫度分布。
太陽光電系統發電量，與太陽能電池的面積和太陽輻射量成正比，然而當PV溫度上升時發電效率則會下降。一般非晶矽薄膜太陽能電池的效率溫度係數為-0.28%/oC，意即每當溫度上升一度，則效率將會下降0.28%，此處提到的效率(100%)為太陽能電池在標準測試狀況下發電之瓦數。為了提升太陽能電池的發電效率，設計一散熱系統是必需的。本研究在能準確預測BIPV的溫度分布之後，將進一步的利用散熱系統來提升太陽能電池的發電量。
當溫度模擬模型建立完成之後，在溫度模擬模型之邊界條件上考慮風場速度，並建立出散熱模擬模型，此模擬將與實驗結果進行比對，已確認此模型具一定準確性。散熱系統之概念為利用自然無動力通風球，透過環境風速推動，將環境中之空氣導入空氣層中，使空氣層中空氣流動並將熱空氣排出空氣層，以達散熱效果。

This research based on NexPower 5th BIPV, and simulating the temperature for Insulating Glass module. Temperature distribution was simulated with different wind speeds and Solar irradiation. The simulation results were very consistent with experiments
The electrical energy of Solar system was proportional to area of the Solar battery and Solar irradiation. However, the efficiency decreased when PV temperature increased. The temperature coefficient of a-si (amorphous silicon) thin film solar cell was -0.28 %/oC. It means that when cell temperature increased one degree, the efficiency will decrease 0.28%. In order to improve the efficiency of solar cell, the designing a radiator system was essential. When the simulation can predict BIPV temperature distribution accurately, the cooling system will be used to increase the electrical energy of solar cell.
After established the temperature simulation module, modifying the boundary conditions of module to built cooling simulation module was continued. The result of cooling simulation module was compared with experiment to confirm that accuracy. The cooling system was made from the ventilation ball to make air flow and exhaust the hot air. The ventilation ball was drove by wind.
