Suppressing deep-level defects at the perovskite bulk and surface is indispensable for reducing non-radiative recombination losses improving efficiency stability of solar cells (PSCs). In this study, two Lewis bases based on chalcogen-thiophene (n-Bu4S) selenophene (n-Bu4Se) having tetra-pyridine as bridge are developed to passivate in film. The uncoordinated Pb2+ iodine vacancy can interact with chalcogen-concave group pyridine through formation acid-base adduct, particularly both be surrounded by concave molecules, resulting effective suppression charge recombination. This approach enables a power conversion (PCE) high 25.37% (25.18% certified) n-i-p PSCs stable operation 65 °C 1-sun illumination 1300 hours N2 (ISOS-L-2 protocol), retaining 94% initial efficiency. Our work provides insight into bowl-shaped base passivation coordinated strategy high-performance photovoltaic devices.

Abstract Photovoltaics (PVs) are a critical technology for curbing growing levels of anthropogenic greenhouse gas emissions, and meeting increases in future demand low-carbon electricity. In order to fulfill ambitions net-zero carbon dioxide equivalent (CO 2 eq) emissions worldwide, the global cumulative capacity solar PVs must increase by an magnitude from 0.9 TW p 2021 8.5 2050 according International Renewable Energy Agency, which is considered be highly conservative estimate. 2020, Henry Royce Institute brought together UK PV community discuss technological infrastructure challenges that need overcome address vast accelerating deployment. Herein, we examine key developments community, especially progress made field since this earlier roadmap, bringing experts primarily across breadth community. The focus both on improving efficiency, stability levelized cost electricity current technologies utility-scale PVs, as well fundamental questions novel can have significant impact emerging markets, such indoor space agrivoltaics. We advanced metrology computational tools, synergies between fuels, offer perspective environmental sustainability industry. Through emphasize promising pathways forward short- long-term, communities working range maturity learn each other.

Abstract Wide‐bandgap perovskite solar cells, which are essential for tandem photovoltaics, easily suffer from open‐circuit voltage ( V OC ) losses due to challenges in suppressing halogen heterogeneity and defect‐related nonradiative recombination the active layers. Herein, a multifunctional fluorine‐containing additive of 8‐pentafluorobenzyloxy quinoline (8‐PFBQ) is explored modulate crystallization defect properties wide‐bandgap (1.67 eV) perovskites, enhancing both efficiency operational stability ensuing cells. It demonstrated that group 8‐PFBQ can strongly coordinate with lead ions fluorinated benzyl effectively interacts organic halides through anion‐π hydrogen bonding interactions simultaneously. These synergistic effects improve crystal quality composition homogeneity, holistically reducing defects The resulting cells achieve champion power conversion 22.22%, featuring high 1.243 two‐fold enhancement stability. This work presents an alternative strategy management offering insights advancements single‐junction photovoltaics.

Abstract Self‐assembled molecules (SAMs) have been widely employed as hole transport layers (HTLs) in inverted perovskite solar cells (PSCs). However, the carbazole core of [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic acid (Me‐4PACz) is insufficiently effective for passivating defects at “bottom” films, and weak anchoring ability phosphate groups toward NiO x substrate appears to promote formation dimers, trimers, higher‐order oligomers, resulting molecular accumulation. Herein, a novel technique proposed combine Me‐4PACz with different thiol modify buried interface PSCs. Molecular dynamics simulations infrared scattering‐type scanning near‐field optical microscopy (IR s‐SNOM) results show that co‐depositing forms hybrid SAMs densely uniformly cover surface. The island‐like structure serves template forming bulk heterojunction composed interpenetrating networks MA‐rich FA‐rich domains, enabling efficient charge generation suppressed bimolecular recombination. Particularly, (3‐mercaptopropyl) trimethoxysilane (MPTMS) effectively prevents aggregation by multi‐dentate anchor on surface through hydrolytic condensation ─OCH 3 groups, while its ─SH passivate uncoordinated Pb 2+ perovskite/HTL interface. Consequently, SAMs‐modified PSC achieve champion photoelectric conversion efficiency (PCE) 25.4% demonstrated better operational stability.
