The commercial manufacturing of perovskite solar modules (PSM) suffers from stability concerns and scalability issues. We demonstrate a hole‐conductor‐free printable module embodiment, which employs triple layer mesoporous TiO 2 /ZrO /carbon as scaffold, is infiltrated by mixed cation lead halide (5‐AVA) x (MA) 1−x PbI 3 light harvester. Here, hole conductor or Au reflector are not employed, instead, the back contact comprises simply printed carbon layer. Upon optimizing thickness alignment...
Directional growth of ultralong nanowires (NWs) is significant for practical application large-scale optoelectronic integration. Here, we demonstrate the controlled in-plane directional perovskite CsPbBr3 NWs, induced by graphoepitaxial effect on annealed M-plane sapphire substrates. The wires have a diameter several hundred nanometers, with lengths up to millimeters. Microstructure characterization shows that NWs are high-quality single crystals, smooth surfaces and well-defined cross...
The tunable hysteresis effect of perovskite solar cells clarifies the importance c-TiO<sub>2</sub>/perovskite interface, and provides significant insights towards understanding this rapidly developing photovoltaic technology.
Semiconducting p-n heterojunctions, serving as the basic unit of modern electronic devices, such photodetectors, solar-energy conversion and light-emitting diodes (LEDs), have been extensively investigated in recent years. In this work, high performance self-powered broad-band photodetectors were fabricated based on vertically stacked heterojunctions though combining p-type WSe2 with n-type Bi2Te3 via van der Waals (vdW) epitaxial growth. Devices heterojunction show obvious current...
The mechanical properties of porous concrete, such as strength and durability, are significantly influenced by moisture transport, particularly in the case recycled aggregate concretes. pore distribution size well ambient temperature surrounding environment, exert a significant influence on transport. This paper establishes fractal Fick’s law, Darcy Richards equation. In conclusion, model for diffusion permeability concrete is established. study examines mechanisms water concrete. comparison...
A multifunctional additive of guanidinium chloride (GuCl) in a CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> perovskite absorber enabled high open-circuit voltage over 1.0 V for printable mesoscopic solar cells based on TiO<sub>2</sub>/ZrO<sub>2</sub>/carbon architecture.
Methylammonium lead halide perovskites have attracted enormous attentions due to their superior optical and electronic properties. However, the photodetection at near‐infrared telecommunication wavelengths is hardly achievable because of wide bandgaps. Here, this study demonstrates, for first time, novel perovskite–erbium silicate nanosheet hybrid photodetectors with remarkable spectral response ≈1.54 µm. Under light illumination, erbium nanosheets can give strong upconversion luminescence,...
Enhancing open‐circuit voltage in CH 3 NH PbI (Cl) perovskite solar cells has become a major challenge for approaching the theoretical limit of power conversion efficiency. Here, first time, it is demonstrated that synergistic effect 2 passivation and chlorine incorporation via controlling molar ratio , PbCl (or MACl), MAI precursor solutions, boosts over 1.15 V both mesoscopic inverted planar cells. Such high can be attributed to enhanced photoluminescence emission carrier lifetime...
Atomically thin two-dimensional (2D) transition metal dichalcogenides (TMDCs) are attractive for applications in a wide range of optoelectronic devices, due to their tremendous interesting physical properties. However, the photoluminescence quantum yield (PLQY) TMDCs has been found be too low, abundant defects and strong many-body effect. Here, we present direct vapor growth WO3–WS2 bilayer heterostructures, with WO3 monolayer domains attached on surface large-size WS2 monolayers. Optical...
Artificial synapse networks capable of massively parallel computing and mimicking biological neural can potentially improve the processing efficiency existing information technologies. Semiconductor devices functioning as excitatory inhibitory synapses are crucial for developing intelligence systems, such traffic control systems. However, achieving reconfigurability between two working modes (inhibitory excitatory) bilingual synaptic behavior in a single transistor remains challenging. This...
A low-temperature solution-processed inorganic p-type contact material of vanadium oxide (VOx) was developed to fabricate planar-heterojunction perovskite solar cells. Using a solvent-assisted process, high-quality uniform and compact (CH3NH3PbI3) films were deposited on VOx coated substrates. Due the high transmittance quenching efficiency layers, power conversion over 14% achieved.
