Abstract

In this study, a non-selenized CuInGaSe2 (CIGS) solar device with textured zinc oxide (ZnO) antireflection coatings was studied. The ZnO nanostructure was fabricated by a low-temperature aqueous solution deposition method. With controlling the morphology of the solution-grown tapered ZnO nanorod coatings, the average reflectance of the CIGS solar device decreased from 8.6% to 2.1%, and the energy conversion efficiency increased from 9.1% to 11.1%. The performance improvement in the CuInGaSe2 thin-film solar cell was well explained due to the gradual increase of the refractive index between air and the top electrode of solar cell device by the insertion of the ZnO nanostructure. The results demonstrate a potential application of the ZnO nanostructure array for efficient solar device technology.

摘要

在这项研究中，研究了一种具有纹理化氧化锌（ZnO）抗反射涂层的非硒化铜铟镓硒（CIGS）太阳能器件。ZnO 纳米结构是通过低温水溶液沉积法制备的。通过控制溶液生长的锥形 ZnO 纳米棒涂层的形态，CIGS 太阳能器件的平均反射率从 8.6%降低到 2.1%，能量转换效率从 9.1%提高到 11.1%。由于插入 ZnO 纳米结构，逐渐增加了太阳能电池器件的空气和顶电极之间的折射率，因此可以很好地解释铜铟镓硒薄膜太阳能电池性能的提高。研究结果表明 ZnO 纳米结构阵列在高效太阳能器件技术中有潜在的应用。
