太陽能電池之光電量測儀器研製與應用

本論文在探討自製太陽能電池之光電量測儀器，將各光電量測儀結合LabVIEW圖控程式以達到自動化量測目的，並應用於實驗室所自行開發的染料敏化奈米太陽能電池(DSSC)及商用非晶矽太陽能電池之光電量測，對各儀器量測結果進行比對及校正。本論文自行架設四點探針量測儀，針對市面上常見的探針材質進行測試及選擇，探針量測點之校正及ITO玻璃於不同燒結溫度下之阻值變化進行探討，得到鎢碳鋼探針量測結果最接近商用四點探針儀，量測結果顯示，在燒結溫度400℃下之ITO玻璃有較低的片電阻值。另外，本論文也自行架設太陽能電池之光電效率量測儀，針對不同濃度之市售染料、含葉黃素與花青素之天然染料及其混成雞尾酒染料所製成的DSSCs做一系列效率量測分析。添加染料為DSSC拓展吸收光譜並提高整體效率的方法，本研究自行架設一單頻光掃描光譜分析儀，以單頻光照射的方式分析太陽能電池之吸收光譜，分析太陽能電池在單頻光照射下之光電轉換效率(Incident Photon-to-Electron Conversion Efficiency, IPCE)關係，結果得知，加入染料後不但紫外光區之IPCE有提升，太陽能電池之吸收光譜擴展至500nm左右，部份染料並有吸收光譜紅移(Red Shift)的現象，但整體而言，DSSC在偏紅外光區無法順利將電子激發逸出；本研究另將IPCE量測儀結合LabVIEW圖控程式對商用非晶矽太陽能電池進行量測，其結果比對雙通道電錶相當符合，在600nm處有最佳IPCE值約10.5%。此外，實驗室自行開發噴霧鍍膜技術，製作DSSC之光電極TiO2薄膜，本論文更自行架設一麥克森干涉儀結合LabVIEW圖控程式進行光電極之厚度量測，並對兩束光重合度及標準厚度試片作校正及分析。

This article is focused on discussing the home-made photoelectric measuring apparatuses including their comparison and calibration. The home-made photoelectric measuring apparatuses are further integrated with the graphical programming language of LabVIEW for automation measurements and also applied in measurements of the laboratorial developed dye sensitized nano solar cell(DSSC) as well as commercial amorphous Si based photovoltaic solar cell. This article builds a four-point probe instrument to measure the electric sheet resistance of ITO glass sintered at different temperature. Many materials of probe are tested and yields that the measured data with tungsten steel probe has the closest approach with the commercial instrument. Calibration of the measured position and measurements of ITO glass at different sintering temperature show that the ITO glass sintered at 400℃ has the lower electric sheet resistance. Moreover, this article also builds a measuring instrument of photoelectric conversion efficiency for analysis of DSSCs with different concentrations of commercial dye, natural dyes including lutein and anthocyanin as well as their mixtures. Adding dye in DSSC is to expand its absorption spectra and further to increase its total efficiency. This article builds a scanning spectrometer to analyse absorption spectrum of the solar cells and the incident photon-to-electron conversion efficiency(IPCE). The results show that the IPCE in the region of UV light is increased, the absorption spectrum is expanded to ca. 500nm, absorption spectrum of red shift is appeared for some dyes due to the added dye. As a whole, the photoelectric effect of DSSC is not occurred in the region of infrared light. This article further integrates the home-made IPCE instrument with LabVIEW and determines the best IPCE value of ca. 10.5% at 600nm for commercial amorphous Si based solar cell. The result agrees to the measured data with dual-channel meter. Furthermore, this article builds a Michelson interferometer integrated with LabVIEW to measure the film thickness of photoelectrode, which is coated by the spray technique in our CCT laboratory. The home-made Michelson interferometer is also finished with calibration and analysis.
