【摘要】：采用電沉積法制備出ZnO致密納米顆粒膜和不同尺寸的納米棒陣列。通過在ZnO上旋涂p型聚合物聚3-己基噻酚(P3HT)與n型富勒烯衍生物[6,6]-苯基-C61丁酸甲酯(PCBM)的混合物,并蒸鍍金屬Ag,制備出不同結構的雜化太陽能電池。通過掃描電鏡、X射線衍射、光致發(fā)光和模擬太陽光光電性能測試,對ZnO的生長條件、晶體形貌及缺陷與太陽能電池性能之間的關系進行了系統(tǒng)研究。結果表明,ZnO的形貌和晶體缺陷的分布對雜化太陽能電池有重要影響,避免共混聚合物與ZnO缺陷聚集區(qū)的直接接觸可有效消除電流泄漏。在電池結構方面,與ZnO納米陣列塊狀結構雜化太陽能電池相比,共形結構的雜化太陽能電池可有效縮短空穴到金屬電極的傳輸距離,增大聚合物與金屬電極的接觸面積,光電轉換效率可提升64%~101%。
[Abstract]:ZnO dense nanocrystalline films and nanorod arrays of different sizes were prepared by electrodeposition. Hybrid solar cells with different structures were prepared by spin-coating p-type polymer poly (3-hexylthiophenol) (P3HT) on ZnO and n-type fullerene derivative [6O6] -phenyl-C61 butyrate (PCBM). The hybrid solar cells were prepared by vaporizing metal Ag,. By means of scanning electron microscope, X-ray diffraction, photoluminescence and simulated solar photoelectricity, the relationship between the growth conditions, crystal morphology and defects of ZnO and the performance of solar cells was studied systematically. The results show that the morphology of ZnO and the distribution of crystal defects have an important effect on hybrid solar cells. Avoiding the direct contact between the blend polymer and the ZnO defect accumulation area can effectively eliminate the current leakage. In terms of cell structure, compared with ZnO nanoarray hybrid solar cells, conformal hybrid solar cells can effectively shorten the distance from hole to metal electrode and increase the contact area between polymer and metal electrode. Optoelectronic conversion efficiency can be increased by 64 / 101.
