Unveiling Morphology Effect on the Negative Capacitance and Large Ideality Factor in Perovskite Light Emitting Diodes

In this article, We have demonstrated the Negative capacitance in PeLEDs for the first time, that depends on morphology. Hope it will show a new way to rethink device physics.

Elucidating tuneable ambipolar charge transport and field induced bleaching at the CH3NH3PbI3/electrolyte interface

In this work, we have investigated charge transport through a perovskite/electrolyte interface using electrochemical impedance spectroscopy (EIS) under illumination and applied bias conditions.

Origin of Low Open-Circuit Voltage in Surfactant-Stabilized Organic-Nanoparticle-Based Solar Cells

In this work, we have investigated the origin of voltage loss and charge trapping in surfactant-stabilized nanoparticle-based devices.

Ion Transport and Stability Issues in Organic–Inorganic Perovskite Materials

In this chapter, some of the major pathways and mechanism related to the ion migration is discussed. The presence of ionic defects/vacancies is responsible for ion migration. However, the activation energy barrier for the migration of ions/vacancies depends on multiple factors, such as nature of ions, crystal structure and migration pathways.
