Comparing Model Parameters of Bulk Heterojunction and Nanoparticulate Photovoltaic Cells Using a Two-diode Model

摘要

The performance of organic solar cells can be influenced by many factors such as device structure, active layer morphology, and active layer material. These performance differences can be seen through their characteristic electrical parameters. The aim of this article is to show the differences in electrical parameter properties that result from differences in active layer morphology. In particular, the differences between bulk heterojunction (BHJ) and nanoparticulate solar cells are determined using a two-diode circuit model. The simulation results show clear differences in photocurrent generation, serial resistance, and shunt resistance between the bulk heterojunction and nanoparticulate photovoltaic cells.
