The inverted p-i-n perovskite solar cells hold high promise for scale-up toward commercialization. However, the interfaces between and charge transport layers contribute to major power conversion efficiency (PCE) loss instability. Here, we use a single material of 2-thiopheneethylammonium chloride (TEACl) molecularly engineer both interface fullerene-C60 electron layer buried NiOx-based hole layer. dual modification results in optimized band alignment, suppressed nonradiative recombination,...
Perovskites with bandgaps between 1.7 and 1.8 eV are optimal for tandem configurations crystalline silicon (c-Si) because they facilitate efficient harvest of solar energy. In that respect, achieving a high open-circuit voltage (VOC) in such wide-bandgap perovskite cells is crucial overall power conversion efficiency (PCE). Here, we provide key insights into the factors affecting VOC cells. We show influence hole transport layer (HTL) on not simply through its ionization potential but mainly...

We propose a nanostructured three-dimensional (nano-3D) solar cell design employing an ultrathin hydrogenated amorphous silicon (a-Si:H) n-i-p junction deposited on zinc oxide (ZnO) nanorod arrays.

The linear and nonlinear optical properties of metal nanoparticles are highly tunable by variation parameters such as particle size, shape, composition, environment. To fully exploit this tunability, however, quantitative information on absorption cross sections is required, well a sufficient understanding the physical mechanism underlying these nonlinearities. In work, we present detailed systematic investigation wavelength-dependent Ag embedded in glass host, which most important...
To guarantee a long lifetime of perovskite-based photovoltaics, the selected materials need to survive relatively high-temperature stress during solar cell operation. Highly efficient n–i–p perovskite cells (PSCs) often degrade at high operational temperatures due morphological instability hole transport material 2,2′,7,7′-tetrakis (N,N-di-p-methoxyphenyl-amine)9,9′-spirobifluorene (Spiro-OMeTAD). We discovered that detrimental large-domain spiro-OMeTAD crystallization is caused by...
Sputtered nickel oxide (NiO x ) has become one of the most promising inorganic hole transport layers for p–i–n perovskite solar cells (PSCs) due to its appealing features such as robust nature, low material cost, and easy integration tandem structures large‐area applications. However, main drawback with NiO ‐based PSCs is typically open‐circuit voltage ( V OC inferior energy‐level alignment, charge mobility, high recombination at interface. Herein, two types phosphonic acid self‐assembled...

Abstract An experimental investigation has been conducted to ascertain the influence of sintering temperature on microstructure and mechanical properties FeCoMo tool steels. The findings reveal that elevated temperatures accelerate growth induce an uneven distribution μ phase. This phenomenon adversely affects three-point bending strength, causing a reduction, simultaneously increasing hardness. Notably, data highlights 1, 170°C as optimal for preserving microstructural uniformity,...
Hydrogen doped indium oxide (In2O3:H) with excellent optoelectronic properties, deposited using atomic layer deposition (ALD), has been made applicable as a window electrode material for silicon heterojunction (SHJ) solar cells. It is particularly challenging to integrate ALD In2O3:H into SHJ cells due low reactivity of the metalorganic precursor cyclopentadienyl (InCp) H-terminated surface a-Si:H. This challenge overcome by simple and effective plasma-based pretreatment developed in this...
Volatile A-cation halide (AX) additives such as formamidinium chloride and methylammonium have been widely employed for high-efficiency perovskite solar cells (PSCs). However, it remains unstudied how they influence the film stoichiometry cell performance operational stability. Hereby, our work shows that over annealing of chloride-containing films leads to a Pb-rich surface, resulting in high initial efficiency, which however decays during maximum power point tracking (MPPT). On contrary,...
Inverted perovskite solar cells (PSCs) prepared by the antisolvent method have achieved power conversion efficiencies (PCEs) of over 23%, but they are not ideal for device upscaling. In contrast, gas‐quenched PSCs offer great potential upscaling, their performance still lags behind. Herein, films through both surface and bulk modifications upgraded. First, a novel modifier, benzylammonium thiocyanate, is found to allow remarkably improved properties, PCE gain limited existence longitudinally...
