Prior-Guided SEM Image Segmentation Enables Quantitative Morphology Assessment and Process Optimization in Perovskite Solar Cells.
Perovskite film morphology strongly affects charge transport, nonradiative recombination, and power conversion efficiency, yet scanning electron microscopy (SEM) remains largely qualitative. Here, a prior-guided SEM analysis framework converts routine micrographs into class-resolved masks, quantitative morphology descr...
