Abstract: 本篇同時針對燃料電池陰極觸媒PtRh以及以CIS、ZnO、CdS等全無機材料製成的薄膜太陽能電池,提出研究。 作為陰極觸媒的PtRh是一種比純Pt有更好催化效果的合金材料,此外,由實驗結果,我們發現它有更佳的甲醇耐性。我們利用液相合成法,並且利用CV、LSV等方式觀察甲醇催化及氧氣還原反應等反應之電化學數據,此外,我們佐以XRD、TEM與XAS等儀器分析材料結構,並以XAS中的EXAFS數據分析結構及表面組成。催化方面,以PtRh31催化效果最好,並且同時展現最佳的甲醇耐性,為這系列觸媒中最為理想的。 II-IV族半導體在文獻中被廣泛討論,而我們所選用的CuInS2即為一種低毒性的II-IV族半導體。我們利用液相合成的CIS作為吸收層,並且在其下層疊CdS層以及ZnO層,最後則為ITO玻璃的多層構造,製作出全無機薄膜太陽能電池。無機太陽能電池比起有機太陽能電池更為耐用,是未來太陽能電池發展的趨勢。我們利用了UV-Vis、IR等光譜儀器測量其光譜性質,並且以SEM分析其結構分層。最後,我們自行製作的全無機太陽能電池元件,在經過鍛燒除去有機物之後,在AM1.5G的模擬光源下,其光電轉換效率為0.088%。
In this paper, we concentrated on PtxRh1-x as the fuel cell cathode catalyst and used CIS, CdS, and ZnO to construct the all inorganic thin film solar cell both. As cathode catalyst, PtRh is an alloy that has better catalysis ability than pure Pt. In addition, according to the experiment result, we found that it has better tolerance to methanol. We employed solution phase synthesis, and used the CV, LSV, and other such method to observe the methanol oxidation reaction, oxygen reduction reaction, and other such electrochemical data. Furthermore, we combined with the XRD, TEM, XAS, and other such instruments to determine the structure of material, and used the EXAFS of XAS to analysis the structure and surface composition. In catalysis, the PtRh31 has the best catalysis ability, and displayed the best tolerance to methanol, it is the most ideal catalyst. The II-IV semiconductors are widely discussed in many paper, and the material CuInS2 what we select is a low toxic II-IV semiconductor. We synthesized CIS as absorption layer, and layered CdS and ZnO under CIS layer, at last there is ITO glass at the bottom to construct the multilayer structure fabricate all inorganic thin film solar cell. The inorganic solar cells are more durable than organic solar cells, that will be the trend of developing solar cells in the future. We used the UV-Vis, IR, and other such spectrometers to analyze the spectral character, and used SEM to observe the layer structure. At last, the all inorganic solar cell we fabricated displayed the power conversion efficiency of 0.088% under simulated AM1.5G illumination after it was treated with annealing.
