Printable mesoscopic carbon perovskite solar cells (CPSCs) are cited as a potential frontrunner to commercialisation, as they are fabricated using low-cost screen printing. Additionally, AVA0.03MAPbI3 γ-butyrolactone precursors produce incredibly stable cells, passing IEC61215:2016 testing in 2020.
Non-toxic γ-valerolactone and Methanol (GVL-MeOH) mixed precursors have shown improved performance at scale (9.04% PCE at 220 cm2 active area) and superior stability towards precipitation to GBL systems. Unlike GBL devices, this work reveals that GVL-MeOH cells do not require humidity treatments for peak performance. PCE instead increases independently of humidity in the days following fabrication due to gradual residual solvent loss and associated crystal realignment. While average PCE enhancements were ~15%, some device PCEs were observed to nearly double. Critically, it appears this ageing step is essential for peak performance, as early encapsulation and extended heating impaired both performance and stability. This work may help inform future work designing scaled-up processes for fabricating high performing perovskite modules.
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.
