Methylammonium Compensation Effects in MAPbI Perovskite Solar Cells for High-Quality Inorganic CuSCN Hole Transport Layers.

Recent studies have demonstrated that copper (I) thiocyanate (CuSCN) has huge potential as a hole extraction material (HEM) for perovskite solar cells. Here, we used CuSCN as a HEM and analyzed its relationships with a methylammonium lead iodide (MAPbI) perovskite layer. The CuSCN dissolved in diethyl sulfide (DES) was spin-coated on the MAPbI layer.

Design of jetty piles using artificial neural networks.

To overcome the complication of jetty pile design process, artificial neural networks (ANN) are adopted. To generate the training samples for training ANN, finite element (FE) analysis was performed 50 times for 50 different design cases. The trained ANN was verified with another FE analysis case and then used as a structural analyzer.
