Abstract 2D halide perovskite materials have shown great advantages in terms of stability when applied a photovoltaic device. However, the impediment charge transport within layered structure drags down device performance. Here for first time, 3D–2D (MAPbI 3 ‐PEA 2 Pb I 4 ) graded interface is demonstrated with synergistic advantages. In addition to significantly improved ambient stability, this combination modifies energy level such way that reduces recombination, leading an ultrahigh V oc...
Compared to the conventional perovskite solar cells (PSCs) containing hole-transport materials (HTM), carbon based HTM-free PSCs (C-PSCs) have often suffered from inferior power conversion efficiencies (PCEs) arising at least partially inefficient hole extraction perovskite–carbon interface. Here, we show that boron (B) doping of multiwalled nanotubes (B-MWNTs) electrodes are superior in enabling enhanced and transport by increasing work function, carrier concentration, conductivity MWNTs....
Operational stability is one of the main obstacles that may hold back commercialization perovskite solar cells (PVSCs).
Abstract The hole transport material (HTM) free carbon based perovskite solar cells (C‐PSCs) are promising for its manufactural simplicity, but they currently suffer from low power conversion efficiencies (PCE) largely because of the voltage loss. Here, a new strategy to increase PCE by incorporating an ultrathin ferroelectric oxide PbTiO 3 layer between electron and halide is reported. resulting C‐PSCs have achieved PCEs up 16.37%, which highest record HTM‐free date, mainly ascribable...
An amorphous Pb–Br precursor was employed to prepare high-quality CH<sub>3</sub>NH<sub>3</sub>PbBr<sub>3</sub>with conformable oriented crystallization.
We report an exploratory study on the crystal formation behavior of CsPbI2Br perovskite films by adding excess cesium iodide (CsI). Surprisingly, facile co-crystallization CsI and in form spinodal decomposition is observed. Significantly, two phases spontaneously morphing into a remarkably uniform bicontinuous nanoscale blend with high orientational correlation through well-matched (110) plane (200) CsPbI2Br. The produced method not only enjoy compact surface, low defect concentration, long...
A bifunctional PEI/CNT interlayer was designed to bridge the perovskite/carbon interface and passivate trap states for high-performance all inorganic CsPbI<sub>3</sub>-based C-PSCs.
Colloidosomes are usually produced from a series of building blocks with different sizes ranging several nanometers to micrometers or various shapes, such as particles, microrods, and quantum dots. can possess variety characteristics in terms photics, electrology, mechanical strength, selective permeability, derived their blocks. However, poor stability complicated synthesis processes have limited the applications colloidosomes. Here, we report new one-pot colloidal chemistry route...
An inverse nanocone array was fabricated to support nanoporous bismuth vanadate as a photoanode for high efficiency solar water splitting.
Carbon-based hole transport material (HTM)-free perovskite solar cells (PSCs) have attracted intense attention due to their relatively high stability. However, power conversion efficiency (PCE) is still low, especially for the simplest paintable carbon-based PSCs (C-PSCs), whose performance greatly limited by poor contact at perovskite/carbon interface. To enhance interface contact, it important fabricate an even-surface layer in a porous scaffold, which not usually feasible roughness of...
Cation mixing has proved to be effective in stabilizing the high-temperature phase of formamidinium (FA)-based perovskites, affording high-performance n–i–p perovskite solar cells (PSCs).
Electrochemically-assisted microwave deposition technology, a facile method for spatially locating the microcrystals of luminescent metal–organic framework (LMOF) films on surface, was reported.
The H<italic>x</italic>MoO<sub>3−y</sub>nanobelts as electrode has been firstly demonstrated with efficiency up to 14.5% in mesoscopic perovskite solar cells. This work thus opens a new direction for developing materials more efficient
The forming Schottky barrier between carbon and perovskite has currently been the bottlenecks to improve performance of carbon-based hole-conductor-free solar cells (C-PSCs). A conventional approach resolving this issue is incorporating a hole-transport material (HTM) in mesoscopic skeleton or chemical modification electrode. Here, we show an innovative strategy that using solution-processed hydrogen molybdenum bronzes (HxMoO3-y) nanobelts, n-type HTM with high work function electrical...
