Abstract

The exceptional magnetic, electrical, and optical properties exhibited by metal halide perovskites (MHPs) have garnered significant interest from the optoelectronic research community in recent decades. Perovskite solar cells (PeSCs) have gained substantial attention due to their inherent advantages, such as solution processability, tunable band gaps, high absorption coefficients, and long carrier diffusion lengths. To optimize the performance and stability of PeSCs, it is crucial to incorporate appropriate charge transport layers (CTLs) and/or interlayers. These CTLs need to possess suitable energy levels for efficient charge injection and transport, while effectively blocking opposite charges. Additionally, the CTL located beneath the perovskite layer plays a critical role as it significantly influences the crystal growth of the perovskite layer and affects the presence of interfacial defects. In this presentation, a new series of conjugated polyelectrolytes (CPEs) will be introduced as ideal interfacial layers and CTLs for various PeSCs devices.
