The fill factor (FF) is an important parameter that determines the power conversion efficiency of an organic solar cell. There are several factors that can significantly influence FF, and these factors interact with each other …
In this paper, we report the dependence of fill factor (FF) on different parameters in organic solar cells. FF is a more sensitive parameter compared to open-circuit voltage (V OC) and short-circuit current density (J SC), and depends on the mobility (μ)–lifetime (τ) product of the bulk material, thickness of the active-polymer layer and on …
One of the most limiting factors in the record conversion efficiency of amorphous/crystalline silicon heterojunction solar cells is the not impressive fill factor value.
