Flexible solar cells have a lot of market potential for application in photovoltaics integrated into buildings and wearable electronics because they are lightweight, shockproof self-powered. Silicon been successfully used large power plants. However, despite the efforts made more than 50 years, there has no notable progress development flexible silicon their rigidity1-4. Here we provide strategy fabricating large-scale, foldable wafers manufacturing cells. A textured crystalline wafer always...
Abstract Recent achievements in amorphous/crystalline silicon heterojunction (SHJ) solar cells and perovskite/SHJ tandem place hydrogenated amorphous (a-Si:H) at the forefront of photovoltaics. Due to extremely low effective doping efficiency trivalent boron tetravalent silicon, light harvesting aforementioned devices is limited by their fill factors (FFs), a direct metric charge carrier transport. It challenging but crucial develop highly conductive doped a-Si:H with minimal FF losses. Here...

Advanced doped-silicon-layer-based passivating contacts have boosted the power conversion efficiency (PCE) of single-junction crystalline silicon (c-Si) solar cells to over 26%. However, inevitable parasitic light absorption doped layers impedes further PCE improvement. To this end, alternative based on wide-bandgap metal compounds (so-called dopant-free (DFPCs)) attracted great attention, thanks their potential merits in terms loss, ease-of-deposition, and cost. Intensive research activity...
Abstract Perovskite solar cells (PSCs) have attracted extensive attention in the photovoltaic field, with their highest power conversion efficiency (PCE) reaching 26%. However, commercialization of PSCs is severely hindered by instability precursor solutions and narrow annealing window for perovskite films. Here, 2,3,5‐trichlorobenzaldehyde (3Cl‐BZH) introduced into organic salt solution to eliminate excess amines through Schiff‐base reactions, avoiding subsequent irreversible amine‐cation...
Transparent conductive oxide (TCO) films, known for their role as carrier transport layers in solar cells, can be adversely affected by hydrolysis products from encapsulants. In this study, we explored the morphology, optical-electrical properties, and deterioration mechanisms of In2O3-based TCO films under acetic acid stress. A reduction film thickness concentration due to acid-induced corrosion was observed. X-ray photoelectron spectroscopy inductively coupled plasma emission spectrometry...
Recent progress in inverted perovskite solar cells (IPSCs) mainly focused on NiOx modification and (PVK) regulation to enhance efficiency stability. However, most works address only monofunctional modifications, identical molecules with the ability simultaneously optimize interface bulk phase have been rarely reported.
