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 ...

Constructing Soft Perovskite–Substrate Interfaces for Dynamic Modulation of Perovskite Film in Inverted Solar Cells with Over 6200 Hours Photostability

open access: yesAdvanced Science, 2022
High‐performance perovskite solar cells (PSCs) depend heavily on the quality of perovskite films, which is closely related to the lattice distortion, perovskite crystallization, and interfacial defects when being spin‐coated and annealed on the substrate

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.
