Anomalous Hysteresis in Perovskite Solar Cells.
TLDR
This work identifies an anomalous hysteresis in the current-voltage curves of perovskite solar cells, hypothesizes three possible origins of the effect, and discusses its implications on device efficiency and future research directions.
Ultrasmooth organic-inorganic perovskite thin-film formation and crystallization for efficient planar heterojunction solar cells.
TLDR
It is found that by using a non-halide lead source (lead acetate) instead of lead chloride or iodide, the perovskite crystal growth is much faster, which allows us to obtain ultrasmooth and almost pinhole-free perovSKite films by a simple one-step solution coating with only a few minutes annealing.
Enhancement of perovskite-based solar cells employing core-shell metal nanoparticles.
TLDR
This work demonstrates photocurrent and efficiency enhancement in meso-superstructured organometal halide perovskite solar cells incorporating core-shell Au@SiO2 nanoparticles (NPs) delivering a device efficiency of up to 11.4%.
Photo-induced halide redistribution in organic–inorganic perovskite films
TLDR
This work provides visual evidence for photo-induced halide migration in triiodide perovskites and reveals the complex interplay between charge carrier populations, electronic traps and mobile halides that collectively impact optoelectronic performance.
Minimizing non-radiative recombination losses in perovskite solar cells
Photovoltaic solar cells based on metal-halide perovskites have gained considerable attention over the past decade because of their potentially low production cost, earth-abundant raw materials, ease
Enhanced photovoltage for inverted planar heterojunction perovskite solar cells
TLDR
This approach produces a wider bandgap top layer and a more n-type perovskite film, which mitigates nonradiative recombination, leading to an increase in Voc by up to 100 millivolts, which led to a stabilized power output approaching 21% at the maximum power point.
