The performance of a photovoltaic device is strongly dependent on the light harvesting properties absorber layer as well charge separation at donor/acceptor interfaces. Atomically thin two-dimensional transition metal dichalcogenides (2-D TMDCs) exhibit strong light–matter interaction, large optical conductivity, and high electron mobility; thus they can be highly promising materials for next-generation ultrathin solar cells optoelectronics. However, short absorption path inherent in such...
Abstract Efficient modification of the interface between metal cathode and electron transport layer are critical for achieving high performance stability inverted perovskite solar cells (PSCs). Herein, a new alcohol‐soluble rhodamine‐functionalized dodecahydro‐ closo ‐dodecaborate derivate, RBH, is developed applied as an efficient interlayer to overcome (6,6)‐phenyl‐C 61 butyrie acid methyl ester (PCBM)/Ag issues. By introducing RBH interlayer, functions traps passivation, interfacial...
Low-cost solution-processed scintillation radiation detection materials are pursued urgently in ionization applications. Scintillators key conversion that absorb high-energy X(γ) photons and convert them into UV–visible photons. Bulk mix organic–inorganic hybrid perovskites (CH3NH3PbCl3–XBrX) have been employed to detect using a photon–photon method. Optical properties were carefully investigated by photoluminescence (PL) spectra, PL lifetime, X-ray excited luminescence (XEL) spectra at room...
Scintillators that convert ionization radiation photons to UV-visible have attracted extraordinary attention. Traditional scintillators are associated with a vacuum photomultiplier tube faces strict constraints of fragility, magnetic fields, and operated voltage, or coupled silicon (SiPM) optical silicone grease.

As the critical property of organic dye, energy level determines thermodynamic possibilities and efficiencies multiple interfacial charge-transfer processes in dye-sensitized solar cells. Thus, a suitable is highly required, selective control becomes quite important systemic objective. Herein, novel planar carbazole unit, which synthesized through simple aryl immobilization, applied as donor segment D–A−π–A dye. The considerable dihedral angle between benzene almost eliminated, thus...
Abstract Perovskite solar cells have emerged as a potential competitor to the silicon photovoltaic technology.

Lead-free halide double perovskites (DPs) have been proposed as stable and promising alternatives to lead perovskites. Understanding the structural-optical properties of DPs is important for their applications. In this study, Cs2AgInCl6 DP nanocrystals, with a direct band gap, were synthesized studied. Because strong electron-phonon coupling leading exciton self-trapping, broad emission large Stokes shift nanocrystals observed. We observed an abnormal blue-shifted accompanied by red-shifted...
Abstract Organic—inorganic hybrid perovskites have attracted considerable attention for developing novel optoelectronic devices owing to their excellent photoresponses. However, conventional nanolithography of remains a challenge because they undergo severe damage in standard lithographic solvents, which prohibits device miniaturization and integration.
