作为铟锡氧化物（ITO）的替代物，制备了具有嵌入在Mn掺杂的氧化锡（MTO）层之间的纳米尺寸的Ag薄膜的MTO/Ag/MTO（MAM）多层透明电极。在室温下通过RF溅射在玻璃衬底上沉积MTO/Ag/MTO薄膜，以评估其作为有机光伏电池（OPV）的透明电极的特性。在不同的工作压力和氧分压下的单层MTO的光学和电学性能进行了研究。在最佳工艺条件下制备的MTO/Ag/MTO多层膜电极在可见光范围（λ=380-780 nm）的方块电阻为10.1-10.6 Ω/sq，透过率为80.1-85.4%。它们的值与商用氧化铟锡（ITO）兼容。使用MTO/Ag/MTO多层电极的常规型本体异质结有机光伏电池（BHJ-OPV）显示出0.62V的开路电压（VOC）、7.12mA/cm 2的短路电流（JSC）、0.62的填充因子（FF）和2.73%的功率转换效率（PCE）。该PCE与商业ITO电极（3.17%）相当。这表明MTO/Ag/MTO多层电极是一种新的有前途的BHJ-OPV透明导电电极。
As an alternative to indium–tin oxide (ITO), MTO/Ag/MTO (MAM) multilayer transparent electrodes with a nano-sized Ag thin film embedded between Mn-doped tin oxide (MTO) layers were prepared. The MTO/Ag/MTO thin films were deposited on a glass substrate by RF sputtering at room temperature to evaluate their characteristics as transparent electrodes for organic photovoltaic cells (OPVs). Optical and electrical properties of the single layer MTO were investigated at various working pressures and oxygen partial pressures. Based on the optimal condition, the MTO/Ag/MTO multilayer electrode showed a sheet resistance of 10.1–10.6 Ω/sq and transmittance of 80.1–85.4% in the visible range (λ=380–780 nm). Their values are compatible with commercial indium–tin oxide (ITO). Conventional-type bulk hetero-junction organic photovoltaic cells (BHJ-OPVs) using the MTO/Ag/MTO multilayer electrode show an open circuit voltage (VOC) of 0.62 V, a short circuit current (JSC) of 7.12 mA/cm2, a fill factor (FF) of 0.62, and a power conversion efficiency (PCE) of 2.73%. This PCE is comparable with a commercial ITO electrode (3.17%). This suggests that the MTO/Ag/MTO multilayer electrode is a new promising transparent conducting electrode for BHJ-OPVs.
