TL;DR: In this paper, the authors summarized the progress in the understanding of the function of fullerenes in perovskite solar cells in blocking leakage through pin-holes, passivating the defects at the pervskite film surfaces and grain boundaries, and modulating the open-circuit voltage of the devices.
Abstract: There is increasing interest in the application of fullerene-based carbon materials in perovskite solar cells for increased efficiency, reduced hysteresis, and improved stability. This Perspective summarizes the progress in the understanding of the function of fullerenes in perovskite solar cells in blocking leakage through pin-holes, passivating the defects at the perovskite film surfaces and grain boundaries, and modulating the open-circuit voltage of the devices. We also critically reviewed several open questions on the functions of fullerenes in perovskite solar cells based mainly on recent progress: How do fullerenes reduce current hysteresis? What is the function of double-fullerene layers? Does the doping of the fullerene by perovskite contribute to eliminating the photocurrent hysteresis at room temperature? Why do some perovskite/fullerene solar cells still have hysteresis at low temperature? Are perovskite solar cells with fullerenes in the intergranular boundaries bulk heterojunction solar cell...

Abstract: Recent advances in the science and technology of composites utilizing carbon nanostructures are reviewed, including experimental results and modelling studies of composite properties and processing. Carbon nanotubes are emphasized, with other carbon nanostructures such as fullerenes, ultradispersed diamond clusters and diamond nanorods also being discussed.

TL;DR: The gram-order of fullerene (C60) with 99.8 wt% purity was isolated from carbon soot by fractional precipitation with 5,11,17,23,29,35,41,47-octa-tert-butylcalix[8]arene-49,50,51,52,53,54,55,56-octol as mentioned in this paper.
Abstract: The gram-order of fullerene (C60) with 99.8 wt% purity was isolated from carbon soot by fractional precipitation with 5,11,17,23,29,35,41,47-octa-tert-butylcalix[8]arene-49,50,51,52,53,54,55,56-octol. This is a very convenient and efficient C60 purification method without any precious apparatus.

TL;DR: In the absence of oxygen, which acts as a triplet state quencher, C60 and C70 have been observed to phototransform from a van der Waals solid to one in which the fullerenes are linked by covalent bonds as discussed by the authors.
