Buried Interface Regulation with a Supramolecular Assembled Template Enables High‐Performance Perovskite Solar Cells for Minimizing the VOC Deficit

Advanced Materials, EarlyView.
Self‐assembled amphiphilic phosphonate‐based supramolecule functions as a perovskite crystallization‐driven template at SnO2/perovskite buried interface, which induces a highly preferred (100) orientation toward out‐of‐plane direction, facilitates carrier extraction and transfer, passivates the intrinsic defects, and achieves a promising efficiency of ...

How to Drawjectory? -- Trajectory Planning using Programming by Demonstration [PDF]

arXiv
A flight trajectory defines how exactly a quadrocopter moves in the three-dimensional space from one position to another. Automatic flight trajectory planning faces challenges such as high computational effort and a lack of precision. Hence, when low computational effort or precise control is required, programming the flight route trajectory manually ...
