6 FAQs about [Solar container of high dielectric constant materials]

Why do organic solar cells have a low dielectric constant?

The majority of organic semiconductors have a low relative dielectric constant (εr < 6), which is an important limitation for organic solar cells (OSCs). A high dielectric constant would reduce the exciton binding energy, reduce charge carrier recombination losses, and thereby enhance the overall device performance of OSCs.

Are high performance OSCs based on high dielectric constant photovoltaic materials still infancy?

Moreover, high performance OSCs based on high dielectric constant photovoltaic materials are still in their infancy. Herein, we report an oligoethylene oxide side chain-containing non-fullerene acceptor (ITIC-OE) with a high relative dielectric constant of εr ≈ 9.4, which is two times larger than that of its alkyl chain-containing counterpart ITIC.

What is the dielectric constant of non-fullerene acceptors?

Provided by the Springer Nature SharedIt content-sharing initiative Dielectric constant of non-fullerene acceptors plays a critical role in organic solar cells in terms of exciton dissociation and charge recombination. Current acceptors feature a dielectric constant of 3-4, correlating to relatively high recombination loss.

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.

Do high dielectric constants play a significant role in OSCs?

The less phase-separated morphology in blend films due to the reduced crystallinity of ITIC-OE and the too good miscibility between PBDB-T and ITIC-OE are responsible for the lower device performance. This work suggests additional prerequisites to make high dielectric constants play a significant role in OSCs.

How can dielectric constants be increased?

The dielectric constant can be increased by incorporating nanomaterials with high dielectric constants into the nanocomposite , such as the two high dielectric permittivity graphite particles and CNTs added to PDMS and PVDF by Song et al. .
