与原子层沉积、化学气相沉积和溅射等其他沉积技术相比，气溶胶沉积（AD）是制备ZnO薄膜的简单且具有成本效益的技术。在这项工作中，沉积周期的影响，结构，光学和光电转换效率（PCE）的染料敏化太阳能电池的ZnO薄膜沉积AD（AZ）进行了系统的研究。两个周期沉积的ZnO薄膜（AZ-II）的结构，光学和PCE%表现出最高的性能。沉积周期的进一步增加导致结构、光学和PCE性能的恶化。ZnO薄膜的厚度下降，由于磨损的沉积膜的后续流的高能ZnO颗粒。在三个沉积周期（AZ-III）后，可以在ZnO薄膜表面上发现松散结合的颗粒。室温光致发光分析表明，AZ-III薄膜的晶体质量较差，存在间隙氧等晶体缺陷。
As compared to other deposition techniques such as atomic layer deposition, chemical vapour deposition and sputtering, aerosol deposition (AD) is a simple and cost-effective technique to produce ZnO thin films. In this work, the effect of deposition cycles on the structural, optical, and photo-conversion efficiency (PCE) of dye sensitized solar cells of ZnO thin films deposited by AD (AZ) was systematically studied. The structural, optical, and PCE% of two-cycle deposited ZnO thin film (AZ-II) exhibited the highest performance. Further increment in deposition cycle caused deterioration in the structural, optical, and PCE performance. The thickness of ZnO thin films decreased due to abrasion of the deposited film by the subsequent stream of highly energetic ZnO particles. Loosely bound particles could be found on the surface of ZnO thin film after three deposition cycles (AZ-III). The AZ-III films exhibited poor crystal quality, with many crystal defects such as interstitial oxygen as suggested in room temperature photoluminescence analysis.
