Sub Band Gap Operation Limits for Perovskite Light Emitting Diodes
Pradeep R. Nair
Ultra low voltage operation of Perovskite light emitting diodes (PeLEDs) has been demonstrated in recent years as high radiance with minimal power consumption is a desired feature.…
Prospects for market-specific design of Perovskite-Silicon tandem solar cells
Karthik Raitani, Pradeep R. Nair
The quest for optimal perovskite for tandem cell configurations is challenging as it involves several factors ranging from device level performance under field conditions to degrad…
On the efficiency roll-off in Perovskite Light Emitting Diodes
Pradeep R Nair, Advaith Kiran Marathi
Here, we report a comprehensive modeling framework to unravel the efficiency roll-off in Perovskite light emitting diodes (PeLEDs). Our model self-consistently accounts for a posit…
Photoluminescence efficiency droop in Perovskites
Pradeep R. Nair, Karthik Raitani
The commercialization prospects of perovskite light emitting diodes depend on its luminescence efficiency under large carrier densities. The decrease in luminescence efficiency und…
Influence of Phase Segregation on the Hysteresis of Perovskite Solar Cells
Abhimanyu Singareddy, Pradeep R. Nair
Organic-inorganic hybrid perovskite solar cells (PSC) have demonstrated impressive performance improvement. Among the various characteristics, the time-dependent current-voltage (J…
Unraveling the role of excitons in the near ideal performance of perovskite light emitting diodes
Pradeep R. Nair
Recent reports indicate that perovskite based light emitting diodes (LEDs) have achieved an external quantum efficiency (EQE) of 32% - rather an internal quantum efficiency close t…
