Abstract

To replace high-temperature sintered scaffold materials in conventional CH₃NH₃PbI₃-based solar cells, this study demonstrates a new device structure of a bulk intermixing (BI)-type CH₃NH₃PbI₃/TiO₂ nanorod (NR) hybrid solar cell, where dispersed TiO₂ NRs from chemical synthesis are intermixed with the perovskite absorbing layer to form a BI-type perovskite/TiO₂ NR hybrid for device fabrication. Through interface engineering between the TiO₂ NR surface and the photoactive perovskite material of CH₃NH₃PbI₃ by ligand exchange treatment, a remarkable power conversion efficiency (PCE) of over 12% was achieved based on the simple BI-type CH₃NH₃PbI₃/TiO₂ NR hybrid device structure. The proposed hybrids not only provide great flexibility for deposition on various substrates through spin coating at low temperatures but also enable layer-by-layer deposition for the future development of perovskite-based multi-junction solar cells.
