Improving the morphology and structure of perovskite solar cells using different hole-carrying layers
Abstract
In this work, the morphological and structural properties of PEDOT:PSS and PTAA materials as hole-transporting layers (HTLs) were analyzed. Optical measurements showed that the PTAA film has high transmittance in the visible light region. Atomic Force Microscopy (AFM) and Scanning Electron Microscopy(SEM) images confirmed that the perovskite grain size and density in the perovskite composition of the PTAA-based perovskite solar cells (PSCs) were larger. The PSCs using PTAA had better charge separation and higher energy storage. Therefore, this material is better than PEDOT:PSS and is considered a promising option for PSCs in the future.
