Abstract Optimizing the interface between perovskite and transport layers is an efficient approach to promote photovoltaic performance of inverted solar cells (IPSCs). Given decades advances in bulk materials optimization, IPSCs has been pushed its limits by engineering with a power conversion efficiency (PCE) over 25% excellent stability. Herein, n‐type polymeric semiconducting material, PY‐IT, that shown remarkable organic photovoltaics, introduced as regulator ETL. Encouragingly, this...

Additionally, historical parameters for future prediction. The demonstrated in Jiangsu Province, China, where chemical...
Due to the inherent ill-posed nature of 2D-3D projection, monocular 3D object detection lacks accurate depth recovery ability. Although deep neural network (DNN) enables depth-sensing from high-level learned features, pixel-level cues are usually omitted due convolution mechanism. To benefit both pow-erful feature representation in DNN and geomet-ric constraints, we reformulate estimation as a progressive refinement problem propose joint semantic geometric cost volume model error....
