Effect of Bromine Doping on Charge Transfer, Ion Migration and Stability of the Single Crystalline MAPb(BrxI1−x)3 Photodetector
Mahapatra, Apurba; Prochowicz, Daniel; Kruszyńska, Joanna; Satapathi, Soumitra; Akin, Seckin; Kumari, Hemant; Kumar, Pawan; Fazel, Ziba; Tavakoli, Mohammad Mahdi; Yadav, Pankaj (Royal Society of Chemistry, 2021-10-19)Organic-inorganic halide perovskites (OIHPs) have emerged as a promising semiconductor for the fabrication of efficient optoelectronic devices such as photodetectors (PDs). Among all perovskite composition, the mixed-halide ... -
Elucidation of the role of guanidinium incorporation in single-crystalline MAPbI3 perovskite on ion migration and activation energy
Mahapatra, Apurba; Runjhun, Rashmi; Nawrocki, Jan; Lewiński, Janusz; Kalam, Abul; Kumar, Pawan; Trivedi, Suverna; Tavakoli, Mohammad Mahdi; Prochowicz, Daniel; Yadav, Pankaj (Royal Society of Chemistry, 2020)Ion migration plays a significant role in the overall stability and power conversion efficiency of perovskite solar cells (PSCs). This process was found to be influenced by the compositional engineering of the A-site cation ... -
Interpretation of Resistance, Capacitance, Defect Density, and Activation Energy Levels in Single-Crystalline MAPbI3
