Perovskite solar cells (PSC) capable of open-circuit voltage (VOC) over 1.5 V was fabricated based on a formamidinium lead-bromide (FAPbBr3) perovskite absorber film prepared by sequential deposition procedure using dimethylsulfoxide...
A high open circuit voltage close to 1.4 V is achieved when carbon nanotubes are used as a hole conductor in methyl ammonium lead bromide perovskite solar cells.
