摘要
在这项研究中，我们利用无真空沉积技术制造了具有 ITO/PEDOT:PSS/(PCBM:PTB7)/E-GaIn 纳米结构的平面混合有机太阳能电池（PHOSCs）。活性层由分别作为 n 型和 p 型材料的 PCBM 和 PTB7 组成。PEDOT:PSS 用作空穴传输材料，而 ITO 和 E-GaIn 则分别用作阳极和阴极。无机材料作为第三种成分的加入提高了器件的性能，使其具有高导电性和阳光吸收性，以及良好的溶液加工性。合成并表征了由无机硒化镉（CdSe）和氧化锌（ZnO）组成的球形纳米粒子（SNPs）。利用 TEM、HR-TEM、UV-vis、AFM、VCA 和 SEM 技术测定了硒化镉和氧化锌纳米粒子的光学和形态特性。优化后的器件功率转换效率（PCE）最高，达到 8.2%，短路密度（Jsc）为 15.2 mA/cm2，开路电压（Voc）为 770 mV，填充因子（FF）为 70%。
Effects of inorganic nanoparticle incorporation on the performance of planar hybrid organic solar cells: analysis of electrical and morphological properties
In this study, we fabricated planar hybrid organic solar cells (PHOSCs) with ITO/PEDOT:PSS/(PCBM:PTB7)/E-GaIn nanostructure using vacuum-free deposition. The active layer consisted of PCBM and PTB7 as n-type and p-type materials, respectively. PEDOT:PSS was used as hole-transporting material, whereas ITO and E-GaIn served as anode and cathode, respectively. The incorporation of an inorganic material as third component improved the performance of the device, leading to high conductivity and sunlight absorption, as well as good solution processability. Spherical nanoparticles (SNPs) consisting of inorganic cadmium selenide (CdSe) and zinc oxide (ZnO) were synthesized and characterized. The optical and morphological properties of the CdSe and ZnO nanoparticles were determined using TEM, HR-TEM, UV–vis, AFM, VCA, and SEM techniques. The optimized device showed the highest power conversion efficiency (PCE) of 8.2%, with a short-circuit density (Jsc) of 15.2 mA/cm2, an open-circuit voltage (Voc) of 770 mV, and a fill factor (FF) of 70%.
