Microscopic Analysis of Inherent Void Passivation in Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Yonghui Lee

The presence of voids in perovskite solar cells influences the efficiency because of accelerated charge recombination. The induced electric field near voids due to band bending attracts photogenerated electrons and holes toward the voids, leading to carrie ...

Battery Storage System Optimal Exploitation Through Physics-Based Model Predictive Control

Mario Paolone, Fabrizio Sossan, Dimitri Torregrossa, Emil Namor

Traditionally, the safe operation of a battery energy storage system (BESS) is achieved by imposing conservative constraints on its DC bus current and voltage. By using a computationally efficient single particle model (SPM), we propose to replace these co ...
