Single-junction perovskite solar cells have reached efficiencies larger than 25%. Despite these great advancements, some drawbacks remain such as the fact that the material contains lead. Questions related to transient effects are not conclusively solved in perovskite optoelectronic devices either.
In this talk, I will discuss how in-situ and in-operando measurements can help to relate various measurement data to device performance. Measurements refer to photo- and electroluminescence, optoelectronic transients, impedance spectroscopy, and AFM-based characterization on the nano- and microscale. Materials under investigation are lead-halide perovskite compositions that show photoinduced phase segregation and lead-free double perovskites. Discussed devices are solar cells, also under reverse bias, and light-emitting diodes under pulsed operation. The characterization experiments are accompanied by device simulations and data-based modelling. Focus is on the role the mixed ionic-electron conductivity plays on the working principle of devices and how performance-limiting processes can be identified. The presented insights are of relevance for both, scientists working on device fabrication and researcher looking into the device physics.
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.
