High efficiency and long-term stability are the prerequisites for commercialization of perovskite solar cells (PSCs). However, inadequate non-uniform doping hole transport layers (HTLs) still limits improvements, while intrinsic instability HTLs caused by ion migration accumulation is difficult to be addressed external encapsulation. Here it shown that addition a conjugated phosphonic acid (CPA) Spiro-OMeTAD benchmark HTL can greatly enhance device stability. Featuring an optimal diprotic-acid structure, indolo(3,2-b)carbazole-5,11-diylbis(butane-4,1-diyl) bis(phosphonic acid) (BCZ) developed promote morphological uniformity mitigate across both perovskite/HTL HTL/Ag interfaces, leading superior charge conductivity, reinforced immobilization, remarkable film The dramatically improved interfacial collection endows BCZ-based n-i-p PSCs with champion power conversion 24.51%. More encouragingly, devices demonstrate under harsh environmental conditions retaining 90% initial after 3000 h in air storage.

Hydrogen‐Bond‐Based Polymer‐Ammonium Intermediates Induced Buried Interface Engineering for High‐Performance Inverted Perovskite Solar Cells

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(29)

Published: March 20, 2024

Abstract Perovskite interfaces where defects enrich are pivotal for both device efficiency and stability. Herein, a high‐molecular‐weight polyvinyl pyrrolidone (PVP) is proposed as robust multi‐functional interlayer to engineer the buried interface. Besides well‐known defect passivation, perovskite crystallization intriguingly modulated via formation of hydrogen‐bond‐based polymer‐ammonium intermediates (e.g., PVP‐FA+ or PVP‐MA+, MA FA methylamine formamidine, respectively). The interaction energies derived from density functional theory calculations (−34.5, −26.8, −9.9 kcal mol −1 PVP‐FA + , PVP‐MA PVP‐Pb 2+ ) suggest that PVP predominately interacts with ammonium cations form intermediates, thus largely excluding other chemical interactions retarding crystallization. As such, hydrophilic leads spontaneous spreading yet counterintuitively similar nucleation respect hydrophobic poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine] (PTAA), change preferred crystal orientation, improved crystallinity, remarkably suppressed non‐radiative recombination. These conducive effects jointly minimize open‐circuit voltage loss give rise superior power conversion small‐area large‐area devices.
