Although β-CsPbI3 has a bandgap favorable for application in tandem solar cells, depositing and stabilizing experimentally remained challenge. We obtained highly crystalline films with an extended spectral response enhanced phase stability. Synchrotron-based x-ray scattering revealed the presence of oriented grains, sensitive elemental analyses-including inductively coupled plasma mass spectrometry time-of-flight secondary ion spectrometry-confirmed their all-inorganic composition. further...
The all-inorganic α-CsPbI3 perovskite with the most suitable band gap faces serious challenges of low phase stability and high moisture sensitivity. We discover that a simple phenyltrimethylammonium bromide (PTABr) post-treatment could achieve bifunctional stabilization including both gradient Br doping (or alloying) surface passivation. PTABr treatment on CsPbI3 only induces less than 5 nm blue shift in UV–vis absorbance but significantly stabilize much better stability. Finally, highly...
Tin-based perovskites with narrow bandgaps and high charge-carrier mobilities are promising candidates for the preparation of efficient lead-free perovskite solar cells (PSCs). However, crystalline rate tin-based is much faster, leading to abundant trap states lower open-circuit voltage (Voc ). Here, hydrogen bonding introduced retard FASnI3 perovskite. By adding poly(vinyl alcohol) (PVA), OH…I- interactions between PVA have effects introducing nucleation sites, slowing down crystal growth,...

Defect-triggered phase degradation is generally considered as the main issue that causes instability and limited device performance for CsPbI3 inorganic perovskites. Here, a defect compensation in perovskite through crystal secondary growth of perovskites demonstrated, highly efficient photovoltaics are realized. This achieved by solid-state reaction between bromine salt defective perovskite. Upon reaction, Br- ions can diffuse over entire layer to heal undercoordinated Pb2+ conduct certain...
All‐inorganic lead halide perovskites α‐CsPbI 2 Br with higher thermal stability and phase are promising candidate for optoelectronic application such as photovoltaics. However, the >250 °C high temperature annealing is required to obtain desired photovoltaic active perovskite of Br, which makes it difficult fabrication based on flexible polymer substrate. Here, a facile formation performance all‐inorganic CsPbI solar cell reported, through one‐step method 100–130 low process. The...
Understanding the mechanism of nanoparticle self-assembly is critical significance for developing synthetic strategies complex nanostructures. By encapsulating aggregates Au nanospheres in shells polystyrene-block-poly(acrylic acid), we prevent dissociation and aggregation typically associated with drying solution samples on TEM/SEM substrates.

All-inorganic halide perovskites without volatile components have great potential for long term thermal stability. However, the phase stability of all-inorganic is sensitive to moisture and has been seldom studied. In this work, α-CsPbI2Br was studied in different relative humidity conditions. The resistance can be significantly enhanced by using a polymer or organic molecule capping layer including Spiro-MeOTAD. Although an CsPbI2Br perovskite based device typical Li salt doped Spiro-MeOTAD...
