Do organic solar cells have a low dielectric constant?

Organic solar cells (OSCs) have achieved power conversion efficiencies (PCEs) surpassing 20%, but their development remains hindered by the inherently low dielectric constant (εr) of organic semiconductors, which limits charge transport and contributes to serious recombination losses. Herein, we present a co

Do dielectric properties affect photovoltaic efficiencies in organic solar cells?

The fill factor (FF) of organic solar cells (OSCs), a critically important photovoltaic parameter, is still sub-optimal, often less than 0.8. To further reduce the FF gaps with regard to the Shockley-Queisser upper limit, we present a study unveiling the impacts of dielectric properties on obtaining high FFs and photovoltaic efficiencies in OSCs.

Does a low dielectric constant affect the energy storage property?

However, the low dielectric constant of polymer films limits the maximal discharge energy density, and the energy storage property may deteriorate under extreme conditions of high temperature and high electric field , , .

Does increasing dielectric constant affect photovoltaic performance?

Learn more. Increasing the relative dielectric constant is a constant pursuit of organic semiconductors, but it often leads to multiple changes in device characteristics, hindering the establishment of a reliable relationship between dielectric constant and photovoltaic performance.
