Abstract

Light trapping due to rough transparent conductive oxide (TCO) surfaces is a common and industrially applied technique in thin film silicon solar cells. In this study, we demonstrate a novel light trapping solution using electrochemically deposited, highly doped zinc oxide (ZnO) nanorod arrays which goes beyond standard light management concepts. The n-doped ZnO rods enable the application as front electrode in superstrate configuration. We explain our experimental results by multidimensional solar cell simulations and show how the nanorod array geometry influences the cell performance. The requirement is demonstrated to choose an appropriate average nanorod distance which strongly influences the electrical cell characteristics. The results clearly outline the potential of TCO nanorod technology for enhanced light trapping.
