Why researchers prefer norfullerene based acceptors. Why NFAs has absorption Spectrum tunability? Why electron hole recombination reduces in NFAs compared to FA?
Give some article for reference.

Production with higher yields. Fullerene production needs arc discharges and produces more waste than usable material; we're still talking about 9:1 waste:useful ratios, unless some change I didn't hear of has happened. Fullerenes may absorb nicely, but establishing proper electrical contact is hard with all carbon-based electronics and it's most difficult for fullerenes because they may have a functionalization, but a sphere has no end so the docking isn't that great.
An NFA does not necessarily have spectral tunability, but the NFAs used today are chosen for two advantages:
So, as much as it hurts this guy whose PhD thesis was originally intended to be about Fullerenes and nothing else, it is to be assumed the NFAs will be preferred permanently.
