Abstract

We correlated the texture morphology and the solar cell properties by measuring the distribution in the texture morphology. As a result, the short-circuit current ISC was approximated across various types of substrates by the standard texture height. Furthermore, we investigated the texture morphology from the point of view of the electrical effects. With regard to this point, the open-circuit voltage VOC was correlated to the steepest texture angle. Therefore, we consider that the both of the ISC and the VOC can be improved by controlling the distribution in the texture morphology.
