The ultra-low cost and high efficiency of metal halide perovskite solar cells make these devices promising candidates for building next-generation thin-film photovoltaics. Since their introduction in the early 2000s, perovskite solar cells have been expanding rapidly in photovoltaic performance, from an initial photon conversion efficiency of 3.81% to a most recently certified 25.3%, even though there are some challenges associated with long-term stability and lead toxicity which need to be addressed. Perovskite solar cells can be enhanced both in efficiency and stability using carbonaceous materials which offer highly advantageous possibilities for incorporation into diverse device architectures, from zero-dimensional carbon quantum dots to three-dimensional carbon blacks. We present an overview of recent significant and exciting developments in enhancing the long-term performance and reliability of perovskite solar cells using carbonaceous material of different dimensions in the device architectures. Our review also discusses the major advantages and potential challenges of each method that has been developed in recent studies. We conclude with a discussion of how carbonaceous might be used to improve the efficiency and stability of perovskite solar cells.
