Metal halide perovskites (MHPs) possess advantageous optoelectronic properties, so
perovskite emitters and perovskite light-emitting diodes (PeLEDs) are promising candidates …

Three-dimensional (3D) organic–inorganic lead halide perovskites have emerged in the
past few years as a promising material for low-cost, high-efficiency optoelectronic devices …

The efficiency and stability of perovskite solar cells are essentially determined by defects in
the perovskite layer, yet their chemical nature and linking with the degradation mechanism …

Electrical doping (that is, intentional engineering of carrier density) underlies most energy-
related and optoelectronic semiconductor technologies. However, for the intensely studied …

Perovskite solar cells (PSCs) suffer from significant nonradiative recombination, limiting their
power conversion efficiencies. Here, for the first time, we directly observe a complete …

Photovoltaic solar cells based on metal-halide perovskites have gained considerable
attention over the past decade because of their potentially low production cost, earth …

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 …

Perovskite solar cells represent a promising third-generation photovoltaic technology with
low fabrication cost and high power conversion efficiency. In light of the rapid development …

Halide lead perovskites have attracted increasing attention in recent years for ionizing
