Abstract Long-term stability remains a key issue impeding the commercialization of halide perovskite solar cells (HPVKSCs). The diffusion molecules and ions causes irreversible degradation to photovoltaic device performance. Here, we demonstrate facile strategy for producing highly stable HPVKSCs by using thin but compact semimetal Bismuth interlayer. film acts as robust permeation barrier that both insulates from intrusion undesirable external moisture protects metal electrode iodine...
Efficient and stable parallel perovskite solar module is achieved by slot-die coating.
Exceptionally high efficiencies for organic–inorganic hybrid perovskite solar cells (PSCs) have been achieved. However, their operational stability still needs to be improved. The intrinsic instability of halide perovskites caused by the presence volatile organic cations, as well degradation induced adverse permeation environmental water (H 2 O)/oxygen (O ) and undesired ion diffusion or migration are major reasons. Beyond strengthening themselves, interface engineering is now regarded a...
A one-step dual-additive strategy enables high-quality wide-bandgap perovskite films with efficient defect passivation, resulting in a certified record PCE of 44.72%, high V oc 1.069 V, and an FF 82.3% under U30 light.
Flexible perovskite solar cells (f-PSCs) have emerged as potential candidates for specific mechanical applications owing to their high foldability, efficiency, and portability. However, the power conversion efficiency (PCE) of f-PSC remains limited by inferior contact between flexible buried substrate.

A power conversion efficiency of 17.9% has been obtained for the device with a critical BCP thickness 5 nm. While if layer is too thin or thick, charge accumulation will emerge and lead to performance degradation.
Stability issues and high material cost constitute the biggest obstacles of a perovskite solar cell (PVSC), hampering its sustainable development. Herein, we demonstrate that, after suitable surface modification, low-cost cerium oxide (CeOx) nanocrystals can be well dispersed in both polar nonpolar solvents easily processed into high-quality electron transport layers (ETLs). The inverted PVSC with configuration "NiMgLiO/MAPbI3/[6,6]-phenyl-C61-butyric acid methyl ester (PCBM)/CeOx" has...

Specifically, tris(pentafluorophenyl)borane (TPFPB) is introduced as dopant lower lowest...
Abstract High‐efficiency antimony selenosulfide (Sb 2 (S,Se) 3 ) solar cells are often fabricated by hydrothermal deposition and also comprise a CdS buffer layer. Whereas the use of toxic materials such as cadmium compounds should be avoided, both these issues hinder scaling up to large areas market access. For this reason, co‐sublimation is studied manufacturing process for active layer well Cd‐free layers. To further improve power conversion efficiency (PCE), graded bandgap profile...
