Authors: HABİBE BAYHAN, A. SERTAP KAVASOGLU

Abstract: The paper presents a new analytical method for extracting the diode ideality factor of a p-n junction device using Lambert W-function model and the dark current-voltage data. The extracted values are found to be in good agreement with those calculated experimentally from dark current-voltage characteristics.

Keywords: Ideality factor; Lambert W-function; Solar cell.
