orbitals, plays a fundamental role in determining their optical and electronic properties …

To achieve the full potential of monolithic perovskite/silicon tandem solar cells, crystal
defects and film inhomogeneities in the perovskite top cell must be minimized. We discuss …

Chalcopyrite-based solar cells have reached an efficiency of 23.35%, yet further
improvements have been challenging. Here we present a 23.64% certified efficiency for a …

All‐inorganic cesium lead triiodide perovskites (CsPbI3) have attracted increasing attention
due to their good thermal stability, remarkable optoelectronic properties, and adaptability in …

Band gap tunability of lead mixed halide perovskites makes them promising candidates for
various applications in optoelectronics. Here we use the localization landscape theory to …

Perovskite/silicon tandems have smashed through the 30% efficiency barrier, which
represents a promising step towards high efficiency solar modules. However, the processing …

CsPbI3 perovskite receives tremendous attention for photovoltaic applications due to its

Abstract In this manuscript, Sr 2 CaFe 2 WO 9 triple perovskite, in a powder state, has been
studied in the context of these linear and nonlinear optical properties. This material was …

We suggest a new solar cell loss analysis using the external quantum efficiency (EQE)
measured with sufficiently high sensitivity to also account for defects. Unlike common …
