【摘要】：有機聚合物太陽能電池由于其低成本、輕重量、可溶液加工以及可制備成柔性器件等優(yōu)勢,逐漸成為熱點研究領域之一。然而與傳統(tǒng)無機硅等電池器件相比,有機聚合物太陽能電池穩(wěn)定性差、聚合物載流子遷移率低等,使光電轉換效率較低,所以對有機太陽能電池修飾工藝和有機無機雜化太陽能電池應運而生。本文主要采用交流阻抗譜測試對有機與雜化太陽能電池進行了分析研究,通過分析聚合物光電器件的Cole-Cole圖、Bode圖、C-F特性和C-V特性,對太陽能電池器件的等效電路模型和載流子遷移率進行研究和分析。主要研究內(nèi)容如下:對器件結構為ITO/P3HT:PCBM/Mo O3/Al和ITO/修飾層/P3HT:PCBM/Al的聚合物太陽電池進行修飾層作用研究,并用交流阻抗譜進行修飾器件與空白器件兩類體系的介電性能研究。采用電化學沉積方法和蒸鍍方法制備致密硫化銀納米薄膜,為了確定致密硫化銀納米薄膜的最佳制備工藝,本論文研究了不同電化學沉積條件及其表面活性劑(檸檬酸)和蒸鍍工藝對薄膜形貌和晶體結構的影響,發(fā)現(xiàn)在沉積電壓4 V、沉積時間3 min、p H=3且無檸檬酸的條件下和蒸鍍條件下均可以獲得結晶度高、表面質量好的硫化銀納米薄膜。在制備致密硫化銀納米薄膜的基礎上,本論文制備了含有硫化銀的雜化太陽能電池,并對器件結構為ITO/P3HT:Ag2S(電化學沉積)/Al和ITO/P3HT:Ag2S(蒸鍍)/Al的雜化太陽能電池進行交流阻抗譜的測試研究,進而分析了這兩種工藝條件下器件的介電響應。
[Abstract]:Organic polymer solar cells have become one of the hot research fields due to their advantages of low cost, light weight, solution processing and fabrication of flexible devices. However, compared with traditional inorganic silicon and other battery devices, organic polymer solar cells have poor stability and low polymer carrier mobility, resulting in lower photoelectric conversion efficiency. Therefore, the modification process of organic solar cells and organic and inorganic hybrid solar cells came into being. In this paper, the organic and hybrid solar cells are studied by means of AC impedance spectroscopy. The Cole-Cole, Bode, C-F and C-V characteristics of polymer photovoltaic devices are analyzed. The equivalent circuit model and carrier mobility of solar cell devices are studied and analyzed. The main contents are as follows: the effect of the modified layer on the polymer solar cells with ITO/P3HT:PCBM/Mo O3/Al and ITO/ P3HT:PCBM/Al structure is studied. The dielectric properties of modified devices and blank devices were studied by AC impedance spectroscopy. Dense silver sulfide nanocrystalline films were prepared by electrochemical deposition and evaporation. In order to determine the optimum preparation process of dense silver sulfide nanocrystalline films, In this paper, the effects of different electrochemical deposition conditions, surfactant (citric acid) and evaporation on the morphology and crystal structure of the films were studied. It was found that the deposition voltage was 4 V and the deposition time was 3 min,. Silver sulphide nanocrystalline films with high crystallinity and good surface quality can be obtained under the condition of no citric acid and evaporation. Based on the preparation of dense silver sulfide nanocrystalline thin films, hybrid solar cells containing silver sulfide were prepared in this paper. The electrochemical deposition (ITO/P3HT:Ag2S) / Al and ITO/P3HT:Ag2S (evaporation) / Al hybrid solar cells were measured by AC impedance spectroscopy, and the dielectric responses of the hybrid solar cells were analyzed.
