Narrowband Monolithic Perovskite–Perovskite Tandem Photodetectors [PDF]

open access: yesAdvanced Optical Materials, 2022
AbstractNarrowband photodetectors (PDs) are sought after for many applications requiring selective spectral response. The most common systems combine optical bandpass filters with broadband photodiodes. This work reports a method to obtain a narrowband response in a perovskite PD by the monolithic integration of a perovskite photoconductor and a ...

Layered Perovskites Enhanced Perovskite Photodiodes

open access: yesThe Journal of Physical Chemistry Letters, 2021
Recently, two-dimensional layered perovskites have emerged as effective additives for stabilizing conventional three-dimensional metal halide perovskites. With the addition of layered perovskites, the perovskite-based devices also exhibited enhanced optoelectronic properties, such as reduced nonradiative recombination and ionic migration, strengthened ...

Zwitterions in 3D Perovskites: Organosulfide-Halide Perovskites

open access: yesJournal of the American Chemical Society, 2022
Although sulfide perovskites usually require high-temperature syntheses, we demonstrate that organosulfides can be used in the milder syntheses of halide perovskites. The zwitterionic organosulfide, cysteamine (CYS; +NH3(CH2)2S-), serves as both the X- site and A+ site in the ABX3 halide perovskites, yielding the first examples of 3D organosulfide ...

Hybrid Perovskite/Perovskite Heterojunction Solar Cells [PDF]

open access: yesACS Nano, 2016
Recently developed organic-inorganic hybrid perovskite solar cells combine low-cost fabrication and high power conversion efficiency. Advances in perovskite film optimization have led to an outstanding power conversion efficiency of more than 20%. Looking forward, shifting the focus toward new device architectures holds great potential to induce the ...

Organometallic Perovskite Metasurfaces [PDF]

open access: yesAdvanced Materials, 2017
Organometallic perovskites, solution-processable materials with outstanding optoelectronic properties and high index of refraction, provide a platform for all-dielectric metamaterials operating at visible frequencies. Perovskite metasurfaces with structural coloring tunable across visible frequencies are realized through subwavelength structuring ...

Perovskite-perovskite tandem photovoltaics with optimized band gaps [PDF]

open access: yesScience, 2016
Tandem perovskite cells The ready processability of organic-inorganic perovskite materials for solar cells should enable the fabrication of tandem solar cells, in which the top layer is tuned to absorb shorter wavelengths and the lower layer to absorb the remaining longer-wavelength light.
