Abstract :
We investigated novel surface treatment and its impact on silicon photovoltaic cells. Using 2-step etching methods, we have changed the nanostructure on pyramid surface so that less light is reflected. In addition, it has been shown that carrier lifetime through the process optimization was not degraded. The results of this experiment represent a promising guideline for improving the high-efficiency solar cells by introducing sub-texturing process.
