Metal halide perovskites used in perovskite solar cells (PSCs) achieve impressive power conversion efficiencies (PCEs) of up to 26.7%.1 Recent advances have improved PCEs in small-area PSCs and larger devices, including 1 cm² area and modules. These achievements are due to the unique properties of perovskite films, including micron-scale carrier diffusion lengths and strong optical absorption across the ultraviolet to near-infrared spectrum.
N,N-dimethylformamide (DMF) has been the primary solvent used for depositing perovskite thin films in combination with the antisolvent method. Although effective, this process has significant drawbacks: DMF's carcinogenicity, the environmental impact of using large quantities of antisolvents such as toluene and chlorobenzene, and the technical expertise required.
Our previous work established a technique for fabricating large-grain, highly crystalline perovskite thin films without employing the antisolvent method. This method utilized DMF as the primary solvent, complemented by a high-boiling-point, low vapor pressure auxiliary solvent, and a Lewis base.2~5
This study advances our prior findings by employing 2-methoxyethanol, a non-carcinogenic auxiliary solvent, alongside additives to achieve smooth, highly crystalline thin films without using the antisolvent method. The solar cell performance of devices with ITO or FTO / PFN /SnO₂ / perovskite / Spiro-OMeTAD / Ag configurations will be presented.5

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.
