Abstract

Abstract Carbon‐based CsPbI ₃ perovskite solar cells without hole transporter (C‐PSCs) have achieved intense attention due to its simple device structure and high chemical stability. However, the severe interface energy loss at the CsPbI ₃ /carbon interface, attributed to the lower hole selectivity for inefficient charge separation, greatly limits device performance. Hence, dipole electric field (DEF) is deployed at the above interface to address the above issue by using a pole molecule, 4‐trifluoromethyl‐Phenylammonium iodide (CF ₃ ‐PAI), in which the ─NH ₃ group anchors on the perovskite surface and the ─CF ₃ group extends away from it and connects with carbon electrode. The DEF is proven to align with the built‐in electric field, that is pointing toward carbon electrode, which well enhances hole selectivity and charge separation at the interface. Besides, CF ₃ ‐PAI molecules also serve as defect passivator for reducing trap state density, which further suppresses defect‐induced non‐radiative recombination. Consequently, the CsPbI ₃ C‐PSCs achieve an excellent efficiency of 18.33% with a high V _OC of 1.144 V for inorganic C‐PSCs without hole transporter.
