摘要

在目前科技發達時代進步的生活中，由於燃料能源價格飆漲及環保意識抬頭，太陽能已成為當今許多學術研究中所使用的能源來源之一，其具有隨處可取、不需花費以及不會對自然環境產生任何汙染等優點。近年來許多太陽能電池相關研究項目僅限於太陽光電轉換部分，本文研究主要探討利用太陽能電池所產生的熱能結合熱電轉換器裝置特性增加提升儲電效果，其可以提升太陽能電池發電效率，另外熱電模組冷端散熱裝置可以幫助太陽能板散熱，以延長太陽能板使用壽命。
實驗中運用氧化銫鎢(Cs0.33WO3)奈米材料運用其具有吸收紅外光波長之特性，使用UV/VIS/NIR吸收光譜儀及980nm雷射光等儀器量測其吸收光譜及溫度變化特性，並將氧化銫鎢奈米材料塗佈於太陽能電池上放置於熱電轉換器上方，探討其對太陽能電池結合熱電轉換器輸出效率之影響。另外在此以紅外線照護燈、太陽能模擬器及戶外太陽光測試氧化銫鎢對紅外光吸收的能力，是否可增加太陽能電池及熱電轉換器之輸出儲能效率。在三種不同環境下之光源所研究出的結果發現，氧化銫鎢奈米材料能增加熱電轉換的輸出效率，與無塗佈的效果相比，當使用氧化銫鎢0.66wt%的濃度材料時，可提升0至5.1%溫度，也同時增加熱電轉換器之輸出0至14.4%電壓。

In the current progress in the age of technological advancement, solar energy has become one of the sources of energy used in many academic research today due to soaring fuel and energy prices and rising awareness of environmental protection. It has everything that is desirable, no cost, and no natural The environment produces any pollution and other advantages. In recent years, many solar cell related research projects have been limited to solar photovoltaic conversion. The research in this paper mainly discusses the use of thermal energy generated by solar cells combined with the characteristics of thermoelectric converter devices to increase the storage efficiency, which can improve solar cell power generation efficiency, and thermoelectric modules. The cold junction heat sink helps the solar panel to dissipate heat to extend the life of the solar panel.
In the experiment, strontium oxide tungsten (Cs0.33WO3) nanomaterials were used to absorb the wavelength of infrared light, and the absorption spectrum and temperature change characteristics were measured by instruments such as UV/VIS/NIR absorption spectrometer and 980 nm laser light. The yttrium-tungsten-tungsten nano-material is coated on a solar cell and placed above the thermoelectric converter to investigate its effect on the output efficiency of the solar cell combined with the thermoelectric converter. In addition, the ability of infrared light to absorb infrared light by infrared light, solar simulator and outdoor sunlight can increase the output energy storage efficiency of solar cells and thermoelectric converters. The results of light sources in three different environments have found that yttrium-tungsten-tungsten nano-materials can increase the output efficiency of thermoelectric conversion, and when using a concentration of 0.66 wt% of yttrium-tungsten oxide, compared with the effect of no coating, It can increase the temperature from 0 to 6.7%, and also increase the output of the thermoelectric converter from 0 to 14.4%.
