Organic-inorganic metal halide hybrid perovskites in solar cells, or simply “perovskite solar cells (PeSCs)” are poised to revolutionize the photovoltaics industry. Record power conversion efficiency (above 22% in the laboratory) achieved by exploiting the key processing merits of perovskites – their inherent solution-processability and low-temperature sintering requirements – promises a disruptive breakthrough by lowering the cost of energy output. The challenge now lies in maintaining the high efficiencies achieved in the laboratory while advancing the core processing merits of perovskites through an industry-relevant scalable manufacturing method and environment. Most laboratory cells are processed in an inert atmosphere and make the use of spin-coating methods for the deposition of the numerous functional layers comprised in the solar cell. Both practices represent cost bottlenecks to delivering the goal of cheap power: spin coater is not scalable to a continuous processing scheme while maintaining inert environment in industrial-scale manufacturing would be costly as well as limiting to operational-freedom. Fast and continuous manufacturing making use of scalable printing and coating methods in an ambient environment combined with low temperature drying steps epitomizes the ideal low-cost high-throughput production method for harnessing perovskites’ full potential. Depending on the intended application, both sheet-to-sheet fabrication on glass and roll-to-roll fabrication on flexible substrates can be envisioned. A planar device configuration in which the perovskite film is deposited in a one-step process in combination with the use of an anti-solvent or gas-assisted quenching remains the simplest and a cost-effective method. These methods are arguably the most commonly used approaches to generate uniform, pinhole-free perovskite films in the laboratory. In this talk, we will present our experience in translating gas and antisolvent-assisted perovskite film formations to industry-relevant scalable fabrication methods for the fabrication of one-step planar devices. Both laboratory batch-to-batch processing on glass and roll-to-roll on flexible substrate with the use of scalable coating methods under ambient conditions will be discussed.
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.
