Abstract:	本論文以設計開發小型側聚光元件，將之應用於行動電源裝置為目標。選用聚甲基丙烯酸甲酯(PMMA)作為聚光元件材料，運用PMMA之折射率特性，設計V型反射溝槽，於不同反射位置產生不同角度的反射面，藉由這些反射面將光線在PMMA中反射至側邊。以軟體計算輔助反射面之設計，且運用光學軟體模擬分析結果。所設計之聚光元件製作完成後，量測該元件之實際表面輪廓。我們使用光學顯微鏡做為加工後表面輪廓的測量工具，量測加工造成的導角、偏移公差、表面鍍膜反射率等數據，以重新在光學軟體中建立模型，並且模擬分析加工後之結果。在效率量測方面，將聚光元件放置於太陽光模擬器中，量測I-V特性，得到實驗實際功率，並與模擬結果進行分析比較。最後將數個聚光元件組成一個充電模組，並將所得到的電能充入行動電源裝置，以驗證此側聚光型太陽能電池系統之效能。 ;In this research, the design of planar solar concentrator (PSC) will be applied to portable charger. Using polymathic methacrylate (PMMA) as the material, and use the characteristics of refractive index to design the planar solar concentrator. Designing the V-shape, and reflection surfaces at different angles in different reflection position. With these reflection surfaces reflecting the light to the side of planar solar concentrator. Using computer software to calculate the reflector surfaces, and use the LightTools to analysis. After the design of concentrator is finished by injection molding, measuring the surface profile. We use the optical microscope as the measuring instruments to measure lead angles, tolerance, and coating reflectivity data. Re-establishing the model in LightTools, and get the result of simulation. For measuring efficiency, the planar solar concentrator (PSC) is placed in solar simulator, and measuring the I-V curve. We also get the real power, and compared with the data of simulation. Finally, a number of PSC to form a module, and store the electric energy to the portable charger to verify the effectiveness of the PSC system.
