Low-Temperature Growing Anatase TiO₂/SnO₂ Multi-dimensional Heterojunctions at MXene Conductive Network for High-Efficient Perovskite Solar Cells.

ABSTRACT: A multi-dimensional conductive heterojunction structure, composited by TiO₂, SnO₂, and Ti₃C₂T_X MXene, is facilely designed and applied as electron transport layer in efficient and stable planar perovskite solar cells. Based on an oxygen vacancy scramble effect, the zero-dimensional anatase TiO₂ quantum dots, surrounding on two-dimensional conductive Ti₃C₂T_X sheets, are in situ rooted on three-dimensional SnO₂ nanoparticles, constructing nanoscale TiO₂/SnO₂ heterojunctions. The fabrication is implemented in a controlled low-temperature anneal method in air and then in N₂ atmospheres. With the optimal MXene content, the optical property, the crystalli
