Abstract

A method of protecting a perovskite halide film from moisture and temperature includes positioning the perovskite halide film in a chamber. The chamber is maintained at a temperature of less than 200 degrees Celsius. An organo-metal compound is inserted into the chamber. A non-hydrolytic oxygen source is subsequently inserted into the chamber. The inserting of the organo-metal compound and subsequent inserting of the non-hydrolytic oxygen source into the chamber is repeated for a predetermined number of cycles. The non-hydrolytic oxygen source and the organo-metal compound interact in the chamber to deposit a non-hydrolytic metal oxide film on perovskite halide film. The non-hydrolytic metal oxide film protects the perovskite halide film from relative humidity of greater than 35% and a temperature of greater than 150 degrees Celsius, respectively.

Making and Breaking of Lead Halide Perovskites

Journal Article Manser, Joseph S. ; Saidaminov, Makhsud I. ; Christians, Jeffrey A. ; ... - Accounts of Chemical Research

A new front-runner has emerged in the field of next-generation photovoltaics. A unique class of materials, known as organic metal halide perovskites, bridges the gap between low-cost fabrication and exceptional device performance. These compounds can be processed at low temperature (typically in the range 80-150 °C) and readily self-assemble from the solution phase into high-quality semiconductor thin films. The low energetic barrier for crystal formation has mixed consequences. On one hand, it enables inexpensive processing and both optical and electronic tunability. The caveat, however, is that many as-formed lead halide perovskite thin films lack chemical and structural stability, undergoing rapidmore »« less

Comparison of hydrolytic and non-hydrolytic atomic layer deposition chemistries: Interfacial electronic properties at alumina-silicon interfaces

Journal Article Marstell, Roderick J. ; Strandwitz, Nicholas C., E-mail: strand@lehigh.edu - Journal of Applied Physics

We report the differences in the passivation and electronic properties of aluminum oxide (Al{sub 2}O{sub 3}) deposited on silicon via traditional hydrolytic atomic layer deposition (ALD) and non-hydrolytic (NH) ALD chemistries. Traditional films were grown using trimethylaluminum (TMA) and water and NHALD films grown using TMA and isopropanol at 300 °C. Hydrolytically grown ALD films contain a smaller amount of fixed charge than NHALD films (oxide fixed charge Q{sub f} {sub Traditional} = −8.1 × 10{sup 11 }cm{sup −2} and Q{sub f} {sub NHALD} = −3.6 × 10{sup 12 }cm{sup −2}), and a larger degree of chemical passivation than NHALD films (density of interface trap states, D{sub it} {sub Traditional} = 5.4 × 10{sup 11 }eV{supmore »« less

Oxygen-induced defects at the lead halide perovskite/graphene oxide interfaces

Journal Article Acik, Muge ; Park, In Kee ; Koritala, Rachel E. ; ... - Journal of Materials Chemistry. A

Here, graphene oxide or its reduced derivative (GO/RGO) replace metal oxides in perovskite photovoltaics to achieve energy band alignment for minimization of the energy barriers at the film interfaces allowing efficient charge transport, and eliminate stability issues. However, the power conversion efficiencies fall in a wide range (~0.6–18%). Therefore, the perovskite growth and nucleation on GO/RGO require fundamental understanding to improve device function for controlled fabrication, which remain a major challenge. We analyze the surface morphology and crystallization of the lead halide perovskites (MAPbX ₃) at 20–300 °C on GO using X-ray diffraction and photoelectron spectroscopy. To determine defect mechanismsmore »« less

Enhanced Nucleation of Atomic Layer Deposited Contacts Improves Operational Stability of Perovskite Solar Cells in Air

Journal Article Raiford, James A. ; Boyd, Caleb ; Palmstrom, Axel ; ... - Advanced Energy Materials

Metal-halide perovskites show promise as highly efficient solar cells, light-emitting diodes, and other optoelectronic devices. Ensuring long-term stability is now a major priority. In this study, an ultrathin (2 nm) layer of polyethylenimine ethoxylated (PEIE) is used to functionalize the surface of C ₆₀ for the subsequent deposition of atomic layer deposition (ALD) SnO ₂, a commonly used electron contact bilayer for p-i-n devices. The enhanced nucleation results in a more continuous initial ALD SnO ₂ layer that exhibits superior barrier properties, protecting Cs _0.25FA _0.75Pb(Br _0.20| _0.80) ₃ films upon direct exposure to high temperatures (200 degrees C) andmore »« less

N and p-type properties in organo-metal halide perovskites studied by Seebeck effects

Journal Article Liu, Qing ; Hsiao, Yu-Che ; Ahmadi, Mahshid ; ... - Organic Electronics

Organo-metal halide perovskites can exhibit co-existed electrical polarizations and semiconducting properties respectively from organic and inorganic components. We find that the Seebeck coefficient can be changed between positive and negative values when the concentration of chloride ions is varied between single-halide (CH ₃NH ₃PbI ₃) and mixed-halide structures (CH ₃NH ₃PbI _xCl _3-x). This indicates that varying the concentration of chloride ions can tune the semiconducting properties between the n-type and p-type regimes in the organo-metal halide perovskites. This temperature-dependent capacitance measurement shows that increasing temperature can cause a change on internal electrical polarization. As a result, we can proposemore »« less
