ABSTRACT

Carbon electrodes, renowned for their excellent moisture and air stability, present a compelling alternative to unstable hole transport materials and costly metal electrodes. In carbon electrode-based perovskite solar cells (C-PSCs), organic materials play a crucial role in optimizing the surface characteristics and electrochemical performance of carbon electrodes, thereby enhancing the photoelectric conversion efficiency. By incorporating organic material additives to modulate the pore structure and surface chemistry of carbon electrodes, the processes of photon absorption and electron transport can be effectively promoted, leading to an improvement in device performance. This article comprehensively reviews the latest research progress of organic C-PSCs, covering their device structures, working principles, as well as the modification methods, advantages, and application effects of organic materials in different layers of C-PSCs. Finally, the applications of in-situ characterization and first-principles calculations in this field are briefly introduced, providing theoretical and experimental support for in-depth research. Based on the above research and analysis, optimization strategies such as enhancing charge selectivity, improving the contact between the electrode and the perovskite layer, and enhancing the quality of the perovskite layer are proposed to drive the further development of organic C-PSCs.
