Abstract SnO 2 has been universally applied as electron transporting layer (ETL) towards the fabrication of highly efficient perovskite solar cells (PSCs), owing to its unique advantages including low‐temperature solution‐processability, high optical, transmittance and good electrical conductivity. Uncoordinated Sn‐dangling bonds on surface exist deep traps capture photogenerated carriers, causing hysteresis device instability. Fullerene derivatives, though being widely utilized passivator...
Near-infrared (NIR) shielding windows can selectively regulate excess solar radiation to reduce heating and cooling energy consumption in a built environment. However, the dissipation of ultraviolet (UV) visible light into waste heat is inevitable, leading inefficient utilization. Herein, tandem spectrally selective power-generating (SSPG) window developed by incorporating oxygen-deficient tungsten oxide WO3-x nanorod-based NIR red-emissive carbon dot-based luminescent concentrators (LSCs)...
Abstract All‐inorganic perovskite solar cells (PSCs) have developed rapidly in the field of photovoltaics due to their excellent thermal and light stability. However, compared with organic–inorganic hybrid perovskites, phase instability inorganic under humidity still remains as a critical issue that hampers commercialization PSCs. We originally propose this work microstrains between lattices/grains play key role affecting stability perovskite. To end, we innovatively design π‐conjugated...
Broadening the alloyed CdSexTe1-x region in absorber layer is key to preparing highly efficient CdTe-based solar cells (SCs). With CdSe prejunction doping, diffusion distance via non-in situ Se doping method restricted, and ions are difficult completely diffuse through whole layer. Moreover, commonly used p-type back contact material CuSCN shows copper characteristics, but S element not an ideal source for CdTe absorber. Thus, it demanding develop new materials with dual activation of Se. In...
Semi-transparent large-area luminescent solar concentrators (LSCs) have been considered an essential part of zero-energy or low-energy consuming buildings in the future. Inorganic colloidal quantum dots (QDs) are promising candidates for LSCs due to advantages a tunable bandgap, engineered large Stokes shift, and relatively high photoluminescence (PL) yield. However, that fabricated using exhibited inferior stability under long-term illumination, demanding great efforts explore highly stable...
Abstract Formamidinium lead triiodide (FAPbI 3 ) has been demonstrated as the most efficient perovskite system to date, due its excellent thermal stability and an ideal bandgap approaching Shockley‐Queisser limit. Whereas, there are intrinsic quantum confinement effects in FAPbI , which unwanted non‐radiative recombination. Additionally, black α‐phase of is unstable under room temperature significant residual tensile stress film. To simultaneously address above issues, a thermally‐activated...
Abstract Solid‐state anion exchange method is easy to handle and beneficial improve stability of CsPbX 3 (X = Cl, Br, I) perovskites nanocrystals (NCs) with respect in liquid phase. However, the corresponding rate rather slow due limited diffusion anions from solid phases, resulting mixed‐halide perovskite NCs. Herein, a fast reversible post‐synthetic quasi‐solid‐state NCs inorganic potassium halide KX salts/polyvinylpyrrolidone (PVP) thin film firstly reported. Original morphology exchanged...
The minimum interface recombination and maximum carrier extraction of perovskite solar cells (PSCs) are important for achieving a better power conversion efficiency (PCE). According to the recent investigations, 3D/2D hybrid systems have been recognized as an effective approach improve stability PSCs. However, large highest occupied molecular orbital energy level gap between 2D hole transport layer (HTL) spiro-OMeTAD would cause losses at interface, which limit open-circuit voltage (Voc)...

Two-dimensional (2D) metal halide perovskite system has attracted significant attentions due its tunable optoelectronic characteristics and outstanding environmental durability. However, quantum wells (QWs) of 2D severely restrain the charge transfer between organic/inorganic layers, resulting in significantly lower photovoltaic performance solar cells (PSCs) contrast to their 3D analogues. To intrinsically refine QW structures for less confinement, we innovatively design D-A-D (D: donor; A:...
