Perovskite solar cells dominated by bimolecular recombination -- how far is the radiative limit?
Kashimul Hossain, Dhyana Sivadas, Dinesh Kabra +1
Here, we report an experimental demonstration of perovskite solar cells dominated by bimolecular recombination and critically analyse their performance against radiative limits. To…
Ionic Charge Imbalance in Perovskite Solar Cells
Dhyana Sivadas, Abhimanyu Singareddy, Chittiboina vinod +1
Ion migration in perovskite solar cells is usually analyzed and understood in terms of charge neutrality condition. However, several recent reports indicate possibility of ionic im…
Ion Mobility Independent Large Signal Switching of Perovskite Devices
Saketh Tirupati, Abhimanyu Singareddy, Dhyana Sivadas +1
The presence of mobile ions in perovskites is well known to influence the device electrostatics leading to a wide variety of anomalous characteristics related to hysteresis, effici…
