Lead (II) perovskite (PV, e.g., CH 3 NH 3 PbI 3– x Cl x ) with 3 wt% polyvinylpyrrolidone (PVP) produces an ≈90 nm film containing a PVP–PV composite consisting of ≈15‐nm‐sized PV nanocrystals. Solar cells using 3 wt% PVP–PV have several advantages over a device using nondoped PV, which include an increase in transparency, stability of the film, efficiency, and reproducibility.
