摘要

在高效率的再生能源使用以及兼具環保與節能概念的議題裡，太陽光能與太陽熱能正如日中天地廣泛被開發與應用。其中太陽光電產業僅管已是全球舉足輕重的產業，但太陽電池的光電轉換效率似乎已達到瓶頸而無法有效地再被提升。至於太陽熱電能源的轉換其效率目前雖然還有待加強(約3~5%)，但其未來潛力卻是讓人寄予厚望。有鑑於此，本研究乃是以熱電能源產生器作為熱電轉換的核心，利用熱電能源產生器模組的冷熱面溫差來產生可用的電源輸出。首先會先設計出熱電能源產生器模組之最佳結構，其乃先用面蓋先將太陽熱能有效地導入本熱電晶片模組之吸熱塗層，並防止熱能的散失，再利用各種吸熱塗層材料有效地吸收住太陽熱能；其次再將該熱源經由導熱材料導至熱電晶片模組之熱端，至於熱電晶片模組的冷端則放置各種有效的散熱材料，完成太陽熱能轉電能模組。實驗證據顯示，以熱電能源產生器作為廢熱轉電的核心技術，並結合導熱、吸熱材料與散熱裝置的運用，能使太陽熱能轉電能模組輸出功率達86mW，轉換效率達1.7%。

In the urgent issue of utilizing the high-efficiency renewable energy sources and possessing the concepts of environmental protection as well as the energy-conserving, the solar light and thermal energies are developed and applied extensively. Although the solar photoelectric industry has become an important global industry, the conversion efficiency of solar cell is seem to reach a bottleneck and difficult to be raised effectively. In this situation, the solar thermoelectric generation will bring a valuable expectation to the human even if its conversion efficiency is still too low (about 3~5%) and required to be greatly promoted so far. Based on the statement mentioned in the above, the thermoelectric generator is the core of thermoelectric transform module in this study, which utilizes the temperature difference between hot end and cold end to generate the available power energy. First, we use cover to collect and transmit solar thermal energy into the heat-absorption layer. The solar heat energy absorbed by the heat-absorption layer and then conducted by the heat-conduction materials will reach the hot end of thermoelectric transform module. In the cold end of thermoelectric transform module, different heat-dissipation materials will be effectively designed to act the heat-dissipation role and ensure the temperature difference between the hot end and cold end being enough. Finally the solar thermoelectric generator is completed. Evidence indicated that the thermoelectric generator indeed acts the kernel technology for waste-heat transformed to renewable electricity. By integrating the solar thermoelectric generator with heat-conduction, heat-dissipation material, and heat-absorption material, power could be produced 86mW and the thermoelectric efficiency is 1.7%.
