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…
Emission limited logarithmic and power law transients in pump-probe spectroscopy of perovskites
Pradeep R. Nair
Optical pump-probe techniques like absorption spectroscopy and microwave conductivity are widely used to characterize the carrier dynamics in perovskites for optoelectronic applica…
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…
Prospects for Perovskite/Silicon tandem solar cells to outperform c-Silicon solar cells at elevated temperatures
Ganga Vinod Chittiboina, Pradeep R. Nair
Successful commercialization of Perovskite/Si tandem solar cells (P/Si TSCs) need a-priori estimation of technological benchmarks to outperform c-Si based technologies under field…
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…
Is more Phase Segregation better for mixed halide perovskite devices: Spatial randomness, Ion migration, and Non-radiative recombination
Abhimanyu Singareddy, Uday Kiran Reddy Sadula, Pradeep R. Nair
Phase segregation is a critical phenomenon that influences the stability and performance of mixed halide perovskite based opto-electronic devices. In addition to the underlying phy…
