In article number 2100080, Maruyama, Jeon, and co‐workers calcinated surfactants from solution‐processable double – walled carbon nanotubes by thermal treatment in Ar to minimize the damage to the nanotubes. This increased the doping effectiveness from 31.9% to 59.7%, which was reflected by the efficiency increase in perovskite solar cell from 16.6% to 17.7%.
