In recent years, some reports indicate that the interfacial engineering using carbon-based nanomaterials additives plays a crucial role in the process of charge carriers and perovskite crystal growth and thereby enhances device performance and operational stability. Here, we review the development of the varieties of carbon-based nanomaterials applications in PSCs, such as hole-transporting layers(HTLs), electron-transporting layers(ETLs), perovskite bulk layer, and their interfaces.Furthermore, we proposed a further suggestion about the optimized preparation conditions for the preparation of PSCs, which may inspire the researcher to discover, design,and manufacture the more efficient perovskite solar cells in academic and industry.展开更多
