Abstract Organolead halide perovskite is a newly emerging low-cost, solution-processable material with broadband absorption from the ultraviolet (UV) to visible (Vis) region, which has attracted great deal of interest in high-performance optoelectronic devices. However, some practicable applications need cover UV–Vis–NIR region for photoelectric conversion, task that remains significant challenge further extending toward near-infrared radiation (NIR) region. Here, best our knowledge, we...
Abstract Atomic layer deposition (ALD) turns out to be particularly attractive technology for the sputtering buffer when preparing semi‐transparent (ST) perovskite solar cells (PSCs) and tandem cells. ALD process island growth substrate is unreactive with reactants, resulting in pin‐hole layer, which causes an adverse effect on anti‐sputtering. Here, p–i–n structured PSCs SnO x as are conducted. The commonly used electron transportation (ETL) PCBM PVK cell that prevents layer‐by‐layer ....
We report the results of electroluminescence-detected magnetic resonance (ELDMR) measurements on efficient two-layer polymer light-emitting diodes (LED's) comprising a hole-transporting layer poly(p-phenylenevinylene) (PPV) and an emissive cyano-substituted PPV derivative (CN-PPV). By comparing ELDMR conductivity-detected (CDMR) with photo- luminescence-detected films polymers making up LED, we are able to identify components CDMR signals processes occurring in either or CN-PPV layers. are,...
Absolute rate constants for ionization of Rb(ns,nd) atoms in collisions with ${\mathrm{SF}}_{6}$ have been measured values n the range 38--106. In addition, kinematics such reactions investigated using Xe(nf) atoms. The data confirm that Rydberg targets attach free low-energy electrons are well described by ``essentially-free''-electron model. Analysis shows cross section \ensuremath{\sigma}(v) electron attachment to at very low energies (\ensuremath{\lesssim}10 meV) is inversely...
Rate constants for ion production in collisions between potassium atoms nd Rydberg states and SF6 CCl4 have been investigated over a range of principal quantum numbers n 9 45. The data suggest that, at the lower values n, electrostatic interactions product ions become important lead to marked decrease free both target species. also demonstrate that only small fraction energy released by dissociative electron attachment appears as kinetic Cl− fragment.
Near-infrared Organic upconversion devices (NIR OUDs), which convert incident low-energy NIR photons to high-energy visible photons, have many advantages such as simple fabrication process, low cost, flexibility, large area fabrication, and inherent pixel-less imaging, play important roles in night vision security applications. In general, OUDs can be realized by integrating the organic photosensitive layer sensitizer with active layers of normal well inverted light-emitting diodes (OLEDs)...
Perovskite solar cells (PSCs) are considered the most promising photovoltaic devices to replace silicon-based because of their low preparation cost and high photoelectric conversion efficiency (PCE). Reducing defects in perovskite films is an effective means improve PSCs. In this paper, a lead chelator was selected mixed into hole transport layers (HTLs) design prepare mesoporous PSCs with structure ITO/PTAA(BCP)/Al

To overcome the efficiency limit of perovskite single‐junction solar cells, it is vital to develop various types tandem cells. Especially, wide‐bandgap (WBG) cells (PSCs) have played an important role in high‐efficiency Herein, indium zinc oxide‐based interfacial structure developed improve performance a WBG PSC and used as transparent electrode for semitransparent (ST) PSCs. This approach minimizes ohmic contact between electron‐transport layer metallic electrode, which also accelerates...
