太陽能電池模組表面潔淨對光電轉換效率之影響性研究與探討

如今，我們正處於全球能源轉型的重要時代。綠色能源將成為未來經濟發展的新動力。在台灣我們繼續尋求新的綠色能源太陽能及風力發電和地熱能等來取代核能發電。它們都是目標綠色能源的發展，我們希望成為台灣的無核家園。政府已通過了5 + 2產業轉型計畫，該計畫也包括2016年10月的綠色能源技術產業創新計畫。根據島內的環保需求，我們引入了大規模的國內和國外投資來推動綠色能源技術，提升太陽能產業發展，提高就業率。此篇論文會以太陽能電池模組表面潔淨對光電轉換效率之影響性研探討，主要是模擬外在汙染的環境會對太陽能電池模組有什麼影響? 實驗元素將有三種材料:砂礫、結晶鹽以及樹木來做實驗項目。用真實的汙染物遮蔽實驗，實測中使用太陽能電池模組測量與COMSOL模擬軟體資料比對，在同樣條件結果實驗中，實測的部分太陽能電池模組轉換效率確實會被影響，而模擬軟體也有相同的下降幅度，而與現實環境中最相似的砂礫和海邊結晶鹽遮蔽的條件，灰塵遮蔽時輸出電壓由無遮蔽到完全遮蔽，電壓值衰減幅度為76.5%；鹽結晶遮蔽時輸出電壓由無遮蔽到完全遮蔽，電壓值衰減幅度為17.6%。以上的實驗數據可以給目前在太陽能模組表面清洗時，但清潔週期該如何評估仍可以用此篇論文參考，運用清洗方式來提升太陽能電池模組功率。關鍵字: 太陽能電池模組表面潔淨度、戶外環境髒污、COMSOL模擬

Nowadays, we are in an important era of energy transformation worldwide. Green energy will be the new driving force for economic development in the future. In Taiwan, we continue pursuing new green energy to replace nuclear power, such as solar and wind power ,geothermal energy. Both of them are the target green energy development and we hope to become nuclear-free homeland in Taiwan. The government has passed The 5+2 Industrial Transformation Plan, which is also included the Green Energy Technology Industry Innovation Plan in October 2016. Based on the environmental protection needs of the island, we has introduced large-scale domestic and foreign investments to promote green energy technology, and upgrade solar power industry development, as well as improve the employment rate. This research will include the effect of the photovoltaic conversion efficiency on the surface cleanliness of the solar photovoltaic modules. It mainly focus on the simulation of the outdoor environmental contaminant on the solar photovoltaic module. There are 3 materials in this experimental project, including particles, crystalline salt, and trees. The surface is covered by contaminant both in solar photovoltaic module and simulation software in the experiment. Under the same condition, the conversion efficiency of solar photovoltaic module is affected by environmental contaminant, and the similar outcome appears in COMSOL simulation software too. The particles and crystalline salt are quite similar to the environmental contaminant coverage condition. If the surface is covered by contaminant, the voltage value is largely reduced by 76.5% from without any contaminant covered. While the surface is covered by crystalline salt, the voltage value is only decreased by 17.6%. The above experimental data could provide a reference to the current cleaning on the surface of solar photovoltaic modules, and how to evaluate the frequency of the periodical cleaning, as well as the ways of cleaning to enhance the conversion efficiency of solar photovoltaic module would be a key study. Key words: surface cleanliness of solar photovoltaic module, outdoor environmental contaminant, COMSOL simulation software
