Abstract

We report on the fabrication and performance of polymer-based inverted solar cells utilizing amorphous indium zinc oxide (a-IZO) as the electron-collecting electrode. Amorphous IZO films of 200 nm thickness were deposited by room temperature sputtering in a high-purity argon atmosphere. The films possessed a high optical transmittance in the visible region (≥ 80%), a low resistivity (3.3 × 10⁻⁴ Ωcm), a low surface roughness (root mean square = 0.68 nm), and a low work function (4.46 ± 0.02 eV). Inverted solar cells with the structure a-IZO/P3HT: PCBM/PEDOT:PSS/Ag exhibited a power conversion efficiency of 3% estimated for AM 1.5G, 100 mW/cm² illumination.

摘要

我们报道了以非晶态铟锌氧化物（a-IZO）作为电子收集电极的聚合物基倒置太阳能电池的制备及其性能。通过在高纯度氩气气氛中进行室温溅射，沉积了厚度为200nm的非晶态IZO薄膜。这些薄膜在可见光区域具有高透光率（≥80%）、低电阻率（3.3×10⁻⁴Ωcm）、低表面粗糙度（均方根=0.68nm）和低功函数（4.46±0.02eV）。结构为a-IZO/P3HT:PCBM/PEDOT:PSS/Ag的倒置太阳能电池在AM 1.5G、100mW/cm²光照条件下的功率转换效率估计为3%。
