It is widely believed that excess/residual lead iodide (PbI2) can affect the performance of
perovskite solar cells. Moderate PbI2 can enhance efficiency by passivating defects, while …

The performance and stability of metal halide perovskite solar cells strongly depend on
precursor materials and deposition methods adopted during the perovskite layer …

Methylammonium lead halide perovskites are attracting intense interest as promising
materials for next-generation solar cells, but serious issues related to long-term stability …

Single crystals represent a benchmark for understanding the bulk properties of halide
perovskites. We have indeed studied the dielectric function of lead bromide perovskite …

A semiconductor that can be processed on a large scale with a bandgap around 1.8 eV
could enable the manufacture of highly efficient low cost double-junction solar cells on …

The performance and stability of organic–inorganic hybrid perovskite solar cells (PSCs) is
sensitive to water and moisture in an ambient environment. Understanding how H2O …

Vacancy-ordered double perovskites of the general formula A 2 BX 6 are a family of
perovskite derivatives composed of a face-centered lattice of nearly isolated [BX 6] units with …

Metal halide perovskite solar cells are rapidly becoming increasingly competitive with
conventional PV technologies. While their efficiencies have been often touted as …

Unreacted lead iodide is commonly believed to be beneficial to the efficiency of
methylammonium lead iodide perovskite based solar cells, since it has been proposed to …

Light-induced photocarrier generation is an essential process in all solar cells, including
