The disorderly distribution of defects in the perovskite or at the grain boundaries, surfaces,
and interfaces, which seriously affect carrier transport through the formation of nonradiative …

Multi-junction (tandem) solar cells (TSCs) consisting of multiple light absorbers with
considerably different band gaps show great potential in breaking the Shockley–Queisser (S …

Radiation detection, using materials to convert high-energy photons to low-energy photons
(X-ray imaging) or electrical charges (X-ray detector), has become essential for a wide range …

Inverted perovskite solar cells have attracted increasing attention because they have
achieved long operating lifetimes. However, they have exhibited significantly inferior power …

We report the profiling of spatial and energetic distributions of trap states in metal halide
perovskite single-crystalline and polycrystalline solar cells. The trap densities in single …

A major thrust of medical X-ray imaging is to minimize the X-ray dose acquired by the
patient, down to single-photon sensitivity. Such characteristics have been demonstrated with …

Because interfacial nonradiative recombination (NRR) has a significant influence on device
performance, the minimization of interfacial NRR losses through interface engineering …

Since the first introduction of the organic–inorganic hybrid perovskite in the field of
optoelectronics, extraordinary progress in both the photoelectric-conversion-efficiency and …

Since the first publication by Miyasaka in 2009 on the use of lead halide perovskite as a light-
harvesting material (Kojima, A.; Teshima, K.; Shirai, Y.; Miyasaka, T. Organometal Halide …

In several photovoltaic (PV) technologies, the presence of electronic defects within the
semiconductor band gap limit the efficiency, reproducibility, as well as lifetime. Metal halide …
