Mesoporous PbI2 Scaffold for High-Performance Planar Heterojunction Perovskite Solar Cells

A mesoporous PbI2 scaffold is demonstrated to achieve high‐performance planar heterojunction perovskite solar cells. A remarkable power conversion efficiency (PCE) of 15.7% is achieved under AM1.5G 100 mW cm−2 solar irradiation with almost no hysteresis. The morphologies of the PbI2 scaffolds can be...

Description
Summary:A mesoporous PbI2 scaffold is demonstrated to achieve high‐performance planar heterojunction perovskite solar cells. A remarkable power conversion efficiency (PCE) of 15.7% is achieved under AM1.5G 100 mW cm−2 solar irradiation with almost no hysteresis. The morphologies of the PbI2 scaffolds can be programmed by a controlled nucleation and growth mechanism. Correlations between the PbI2 film morphology and device performance are established.
