Abstract Defect passivation has been recognized as an effective strategy to improve efficiency and stability of perovskite solar cells (PSCs). In this work, in‐depth theoretical calculations experimental characterizations reveal the dual‐site synergistic 1H‐benzimidazole (BIZ), conjugated structure benzene ring tends increase interaction between BIZ perovskite. High‐quality films are thus achieved, with increased grain size, reduced defect density, suppressed ion migration. Simultaneously,...

Learning radiance fields has shown remarkable results for novel view synthesis. The learning procedure usually costs lots of time, which motivates the latest methods to speed up by without neural networks or using more efficient data structures.

It is vital to infer a signed distance function (SDF) in multi-view based surface reconstruction. 3D Gaussian splatting (3DGS) provides novel perspective for volume rendering, and shows advantages rendering efficiency quality. Although 3DGS promising neural option, it still hard SDFs reconstruction with due the discreteness, sparseness, off-surface drift of Gaussians. To resolve these issues, we propose method that seamlessly merge learning SDFs. Our key idea more effectively constrain SDF...
