Perovskite-silicon tandem solar cell are highly promising candidates for the industrialization of perovskite based solar cells. We employ several evaporation techniques such as co-evaporation, sequential evaporation, and the hybrid route to fabricate the uniform perovskite films needed for such tandem devices. Each of these approaches has its own challenges and opportunities. In this talk I will share the progress we have made to gain understanding of the mechanisms, crystallization behavior, and the influencing factors that govern the evaporation process. We were able to use these perovskite films in tandem solar cells reaching efficiencies above 31% on 1 cm² cells. Nevertheless it is not fully clear which evaporation approach is best suited for the scaling of perovskite-silicon tandems. Full evaporation approaches like co-evaporation or sequential evaporation have the advantage of having all steps in the same atmosphere, whereas hybrid evaporation / wet-chemical approaches avoid the challenging evaporation of organic halides but introduce additional complexity in the wet-chemical 2nd step. In this talk I will compare what we have so far learned about all three approaches and will highlight key gaps to be addressed in the future.
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.
