Tin oxide (SnOx) is a commonly used electron transporting material (ETM) in n-i-p (so called “regular”) perovskite solar cells which enables high open circuit voltages (>1.1 V). In addition, low process temperatures render SnOx a good choice for the application in monolithic silicon-perovskite tandem solar cells in which the silicon heterojunction bottom cell prohibits high process temperatures.
In this study, compact layers of SnOx processed from a wet-chemistry approach and via atomic layer deposition were investigated with regard to their performance in regular perovskite solar cells. For this, we deposit the differently processed SnOx as ETM onto indium tin oxide (ITO) coated glass substrates and employ a mixed cation, mixed halide perovskite absorber, a doped Spiro-OMeTAD layer as hole transporting material (HTM) and an Au electrode. Moreover, we characterize the optical and electrical material properties of SnOx layers as well as differences in chemical composition and link those properties to the different performances in perovskite solar cells.
By that we find that in the wet-chemistry process, annealing temperature and layer thickness are critical parameters to the overall cell performance. An increase in annealing temperature from 180°C to 200°C yields an absolute efficiency increase of 2%. Current-voltage measurements on this configuration show a power conversion efficiency of 16.7 % and open circuit voltages up to 1.17 V. A major limitation in this configuration is the relatively moderate fill factor of 68 %.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
