Title: The Molybdenum Oxide Interface Limits the High-Temperature Operational Stability of Unencapsulated Perovskite Solar Cells

Abstract

Here, we report on the improved operational stability of unencapsulated perovskite solar cells (PSCs) aged in an ambient atmosphere at elevated temperatures (70 °C) for >1000 h under constant illumination and bias at 30–50% relative humidity. We identify a previously unseen interfacial degradation mechanism concerning the use of a MoO_x interlayer, which was originally added to increase operational stability. Specifically, the hole-transport layer/MoO_x interface buckles under illumination at 70 °C, which leads to delamination and rapid losses of short-circuit current density corresponding to an average $$t_{80}$$ of ~55 h. By judiciously evaluating various hole-transport layers, interlayers, and contacts, we find that replacing the MoO_x with a VO_x interlayer, regardless of the other components in the solar cell, alleviates this buckling issue due to its higher activation barrier toward crystallization, leading to significant gains in PSC operational stability. Unencapsulated devices aged in an ambient atmosphere with a VO_x interlayer retain 71% of their initial PCE on average after constant illumination and bias at 70 °C for 1100 h ($$t_{80}$$ ~ 645 h). Currently, this is the highest temperature reported for the operational stability of unencapsulated n-i-p PSCs aged in air. Identification of a new facet of the complex degradation mechanisms in PSCs will allow for targeted acceleration testing to speed the deployment of low-cost, long-lasting electricity generation under realistic operating temperatures.

Influence of Electrode Interfaces on the Stability of Perovskite Solar Cells: Reduced Degradation Using MoO_x/Al for Hole Collection

Journal Article Sanehira, Erin M. ; Tremolet de Villers, Bertrand J. ; Schulz, Philip ; ... - ACS Energy Letters

We investigated and characterized the stability of the power output from methylammonium lead iodide perovskite photovoltaic devices produced with various hole-collecting anode configurations consisting of Au, Ag, MoOx/Au, MoOx/Ag, and MoOx/Al. The unencapsulated devices were operated under constant illumination and constant load conditions in laboratory ambient with periodic current-voltage testing. Although the initial efficiencies of devices were comparable across these configurations, the stability of these devices varied significantly due to subtle differences in the electrode structure. Specifically, we found that devices with MoOx/Al electrodes are more stable than devices with more conventional, and more costly, Au and Ag electrodes. Wemore »« less

Atomic layer deposition of vanadium oxide to reduce parasitic absorption and improve stability in n–i–p perovskite solar cells for tandems

Journal Article Raiford, James A. ; Belisle, Rebecca A. ; Bush, Kevin A. ; ... - Sustainable Energy & Fuels

Two critical issues associated with semi-transparent, n–i–p perovskite solar cells for 2-terminal tandem devices are parasitic absorption and long-term instability associated with the widely used spiro-OMeTAD and MoO_x hole transport and buffer layers, respectively. Here in this work, we present an alternative hole contact bilayer that consists of a 30 nm undoped layer of spiro-TTB in conjunction with 9 nm of air-stable vanadium oxide (VO_x ) deposited via atomic layer deposition. The low absorption of UV and visible light in this bilayer results in the fabrication of a semi-transparent perovskite cell with 18.9 mA cm ^-2 of photocurrent, a 14%more »« less

Robust Unencapsulated Perovskite Solar Cells Protected by a Fluorinated Fullerene Electron Transporting Layer

Journal Article Huang, Hsin-Hsiang ; Tsai, Hsinhan ; Raja, Rathinam ; ... - ACS Energy Letters

The emergent perovskite photovoltaics technology faces challenges like the long-term durability combining moisture, thermal, and photo stresses that prevents them from competing with established technologies. In this work, we introduce a series of new fluorinated fullerenes as an electron-transporting layer (ETL) for robust perovskite photovoltaics that deliver a high power conversion efficiency of 21.27% with substantially improved durability against environmental stressing. The hydrophobic nature of the new fullerene protects the unencapsulated perovskite cell with stability over 1400 h in 85% relative humidity. Notably, the unencapsulated device maintained 80% of their original performance (T-80) after being immersed in water for overmore »« less

Thermally Stable Perovskite Solar Cells by Systematic Molecular Design of the Hole-Transport Layer

Journal Article Schloemer, Tracy H. ; Gehan, Timothy S. ; Christians, Jeffrey A. ; ... - ACS Energy Letters

With the burgeoning performance of metal halide perovskite solar cells (PSC), one of the biggest challenges to date is addressing device stability. Within the PSC device stack, charge-selective contact selection has been shown to considerably impact PSC stability. Recently, a triarylamine-based hole-transport layer (HTL) doped with its oxidized organic salt analogue (EH44/EH44-ox) has been shown to bypass the need for hygroscopic lithium salt dopants, enabling high PSC stability in ambient conditions. Despite these promising results, the improved stability came with a power conversion efficiency (PCE) penalty and poor performance above 30 degrees C. Broadening the applicability and understanding of thismore »« less

Tailoring Molecular-Scale Contact at Perovskite/Polymeric Hole Transporting Material Interface for Efficient Solar Cells

Journal Article Sun, Jiaonan ; Ma, Ke ; Lin, Zih‐Yu ; ... - Advanced Materials

Perovskite solar cells (PSCs) have delivered more than 25% of power conversion efficiency (PCE) and incorporating polymers as hole transporting layers (HTLs) can further enhance the stability of devices towards the goal of commercialization. Among various polymeric hole transporting materials, poly(triaryl amine) (PTAA) is one of the promising HTL candidates with good stability; however, the hydrophobicity of PTAA causes problematic interfacial contact with perovskite, limiting the device performance. Using molecular side-chain engineering, we successfully constructed a uniform two-dimensional (2D) perovskite interlayer with conjugated ligands, between three-dimensional (3D) perovskites and PTAA. Further, employing conjugated ligands as cohesive elements, perovskite/PTAA interfacial adhesionmore »« less
