Effect of Various Electron and Hole Transport Layers on the Performance of CsPbI3-Based Perovskite Solar Cells: A Numerical Investigation in DFT, SCAPS-1D, and wxAMPS Frameworks [PDF]
ACS Omega, 2022 CsPbI3 has recently received tremendous attention as a possible absorber of perovskite solar cells (PSCs). However, CsPbI3-based PSCs have yet to achieve the high performance of the hybrid PSCs. In this work, we performed a density functional theory (DFT)

Logistics in the Sky: A Two-Phase Optimization Approach for the Drone Package Pickup and Delivery System [PDF]
IEEE transactions on intelligent transportation systems (Print), 2022 The application of drones in last-mile distribution has been a contentious research topic in recent years. Existing urban distribution modes mostly depend on trucks. This paper proposes a novel package pickup and delivery mode and system wherein multiple

Neuroevolution machine learning potentials: Combining high accuracy and low cost in atomistic simulations and application to heat transport [PDF]
Physical review B, 2021 We develop a neuroevolution-potential (NEP) framework for generating neural network based machine-learning potentials. They are trained using an evolutionary strategy for performing large-scale molecular dynamics (MD) simulations.
