Metal halide perovskite solar cells (PSCs) have undergone rapid progress. However, unstable performance caused by sensitivity to environmental moisture and high temperature is a major impediment commercialization of PSCs. In the present work, low-temperature, glass-glass encapsulation technique using polyisobutylene (PIB) as barrier investigated on planar glass/FTO/TiO2/FAPbI3/PTAA/gold cells. PIB was applied either an edge seal or blanket layer. Electrical connections encapsulated PSCs were...
Abstract We present an industrial tunnel oxide passivated contacts (i‐TOPCon) bifacial crystalline silicon (c‐Si) solar cell based on large‐area n ‐type substrate.

Monolithic perovskite/silicon tandem solar cells promise power-conversion efficiencies (PCEs) exceeding the Shockley-Queisser limit of single-junction cells. The conformal deposition perovskites on industrially feasible textured silicon allows for both lowered manufacturing costs and a higher matched photocurrent density, compared to state-of-the-art tandems using front-side flat or mildly silicon. However, inferior crystal quality perovskite films grown fully-textured compromises...
Abstract Wide‐bandgap (WBG) perovskite solar cells hold tremendous potential for realizing efficient tandem cells. However, nonradiative recombination and carrier transport losses occurring at the perovskite/electron‐selective contact (e.g. C 60 ) interface present significant obstacles in approaching their theoretical efficiency limit. To address this, a sequential engineering (SIE) strategy that involves deposition of ethylenediamine diiodide (EDAI 2 followed by 4‐Fluoro‐Phenethylammonium...
Abstract Perovskite/silicon tandem solar cells hold great promise for realizing high power conversion efficiency at low cost. However, achieving scalable fabrication of wide-bandgap perovskite (~1.68 eV) in air, without the protective environment an inert atmosphere, remains challenging due to moisture-induced degradation films. Herein, this study reveals that extent moisture interference is significantly influenced by properties solvent. We further demonstrate n-Butanol (nBA), with its...

Abstract A facile and eco‐friendly dimethyl sulfoxide‐mediated solution aging (DMSA) treatment is presented to control the crystallization dynamics of methylammonium (MA)‐free wide‐bandgap (WBG) perovskite films, enhancing film quality, morphology for high‐performance tandem solar cells. The comprehensive structural, morphological, characterization analyses reveal that DMSA significantly enhances composition homogeneity while suppressing halide segregation. Consequently, opaque,...
