Vacuum processing of multicomponent perovskites is not straightforward, because the number precursors in principle limited by available thermal sources. Herein, we present a process which allows increasing complexity formulation vacuum-deposited lead halide perovskite films multisource deposition and premixing both inorganic organic components. We apply it to preparation wide-bandgap CsMAFA triple-cation solar cells, are found be efficient but thermally stable. With aim stabilizing phase, add guanidinium (GA+) material obtained CsMAFAGA quadruple-cation with enhanced stability, as observed X-ray diffraction rationalized microstructural analysis. The corresponding cells showed similar performance improved stability. This work paves way toward vacuum complex formulations, important implications only for photovoltaics also other fields application.

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 photovoltaic performance. Here, an anion-engineered additive strategy is developed control crystallization process wide-bandgap films, which enables improved film crystallinity, reduced trap This fabrication 28.6%-efficient heterojunction (certified 27.9%, 1 cm2 ). approach compatible with scalable silicon, demonstrating efficiency 25.1% aperture area 16 . significantly improves operating stability cells, encapsulated retain over 80% their initial performance following 2000 h operation under full 1-sun illumination in ambient conditions.

Abstract Over the past few years, lead‐halide perovskites (LHPs), both in form of bulk thin films and colloidal nanocrystals (NCs), have revolutionized field optoelectronics, emerging at forefront next‐generation optoelectronics. The power conversion efficiency (PCE) halide perovskite solar cells has increased from 3.8% to over 25.7% a short period time is very close theoretical limit (33.7%). At same time, external quantum (EQE) LEDs surpassed 23% 20% for green red emitters, respectively. Despite great progress device efficiencies, photoactive phase instability one major concerns long‐term stability devices limiting their transition commercialization. In this regard, researchers found that LHPs reproducibility performance can be improved by A‐site cation alloying with two or more species, these are named mixed (double, triple, quadruple) perovskites. This review provides state‐of‐the‐art overview different types NCs reported literature, along discussion synthesis, properties, LEDs.

All-perovskite tandem solar cells beckon as lower cost alternatives to conventional single-junction cells. Solution processing has enabled rapid optimization of perovskite technologies, but new deposition routes will enable modularity and scalability, facilitating technology adoption. Here, we utilize 4-source vacuum deposit FA0.7Cs0.3Pb(IxBr1-x)3 perovskite, where the bandgap is changed through fine control over halide content. We show how using MeO-2PACz a hole-transporting material passivating with ethylenediammonium diiodide reduces nonradiative losses, resulting in efficiencies 17.8% based on vacuum-deposited perovskites 1.76 eV. By similarly narrow-bandgap FA0.75Cs0.25Pb0.5Sn0.5I3 combining it subcell evaporated FA0.7Cs0.3Pb(I0.64Br0.36)3, report 2-terminal all-perovskite cell champion open circuit voltage efficiency 2.06 V 24.1%, respectively. This dry method enables high reproducibility, opening avenues for modular, scalable multijunction devices even complex architectures.
