Abstract Large datasets are now ubiquitous as technology enables higher-throughput experiments, but rarely can a research field truly benefit from the data generated due to inconsistent formatting, undocumented storage or improper dissemination. Here we extract all meaningful device peer-reviewed papers on metal-halide perovskite solar cells published so far and make them available in database. We collect over 42,400 photovoltaic devices with up 100 parameters per device. then develop...
This review explores perovskite crystallization in scalable deposition techniques, including blade, slot-die, spray coating, and inkjet printing.
Interface engineering is a common strategy for passivating surface defects to attain open circuit voltages (Voc) in perovskite solar cells (PSCs). In this work, we introduce the concept of polishing thin-film using nanosecond (ns) pulsed ultraviolet laser reduce defects, such as dangling bonds, undesirable phases, and suboptimal stoichiometry. A careful control energy scanning speed improves photophysical properties without compromising thickness. Using polishing, Voc 1.21 V achieved planar...
Perovskite solar cells (PSCs) excel in achieving high open-circuit voltages (VOC) for narrow bandgaps (∼1.6 eV) but face challenges with wide-bandgap perovskites, like methylammonium lead trichloride (MAPbCl3) a 3.03 eV bandgap. These materials are transparent visible absorbing ultraviolet (UV) light. However, uniform film crystallization remains hurdle. Here, we enhance MAPbCl3 by manipulating annealing atmospheres (nitrogen, air, and MACl vapor). Excess vapor improves surface coverage,...
All-inorganic perovskites, such as CsPbI2Br, have emerged promising compositions due to their enhanced thermal stability. However, they face significant challenges susceptibility humidity. In this work,...
Interfaces in perovskite solar cells play a crucial role their overall performance, and therefore, detailed fundamental studies are needed for better understanding. In the case of classical n-i-p architecture, TiO2 is one most used electron-selective layers can induce chemical reactions that influence performance device stack. The interfacial properties at TiO2/perovskite interface often neglected, owing to difficulty accessing this interface. Here, we use X-rays variable energies study...
Atomic layer deposition of aluminum oxide (ALD-Al 2 O 3 ) layers has been extensively studied for stabilizing perovskite solar cells (PSCs) against environmental stressors, such as humidity and oxygen. In addition, the ALD-Al ...
Using high coordination dimethyl sulfide, the anti-solvent bathing technique enables efficient extraction of precursor solvents in perovskite wet film. The resulting highly crystalline films achieve a photovoltaic performance 20.6%.
Interfaces between hybrid perovskite absorber and its adjacent charge‐transporting layers are of high importance for solar cells performance. Understanding their chemical electronic properties is a key step in designing efficient stable cells. In this work, the tapered cross‐section photoemission spectroscopy (TCS‐PES) method used to study methylammonium lead iodide (CH 3 NH PbI ) (MAPI)‐based two configurations, that is, an inverted p –i–n classical n–i–p architecture. It revealed results...
