Bimolecular Crystallization Modulation Boosts the Efficiency and Stability of Methylammonium‐Free Tin–Lead Perovskite and All‐Perovskite Tandem Solar Cells

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: unknown

Abstract The elimination of methylammonium (MA) cation from mixed tin–lead (Sn–Pb) narrow‐bandgap (NBG) perovskites is an effective approach to enhance the operational stability all‐perovskite tandem solar cells (TSCs). Unfortunately, uncontrolled nucleation and crystallization processes MA‐free Sn–Pb usually lead inferior film quality device performance. Herein, a bimolecular modulation strategy reported by using guanidine thiocyanate (GuaSCN) aminoacetamide hydrochloride (AHC) together as additives improve perovskites. It demonstrated that use can effectively crystallinity, increase grain size, induce preferred (100) orientation for corresponding films, leading high‐quality absorber with considerably reduced defect density suppressed non‐radiative recombination. In addition, reduce self‐p‐doping hole concentration within perovskite films charge extraction at perovskite/electron transport layer interface. modified NBG deliver power conversion efficiency (PCE) 22.14%. Coupled wide‐bandgap (WBG) subcell, TSCs give champion certified PCE 27.15%, which highest TSCs. Encapsulated devices maintain 90% initial after 473 h operation.

Published: Jan. 8, 2025

This study presents an efficient methodology for simulating nonadiabatic dynamics of complex materials with excitonic effects by integrating machine learning (ML) models simplified Tamm–Dancoff approximation (sTDA) calculations. By leveraging ML models, we accurately predict ground-state wavefunctions using unconverged Kohn–Sham (KS) Hamiltonians. These ML-predicted KS Hamiltonians are then employed sTDA-based excited-state calculations (sTDA/ML). The results demonstrate that energies, time-derivative couplings, and absorption spectra from sTDA/ML accurate enough compared those conventional density functional theory based sTDA (sTDA/DFT) Furthermore, sTDA/ML-based molecular simulations on two different systems, namely chloro-substituted silicon quantum dot monolayer black phosphorus, achieve more than 100 times speedup the linear response time-dependent DFT simulations. work highlights potential ML-accelerated studying complicated photoinduced large offering significant computational savings without compromising accuracy.
