Vapor phase deposition of organic-inorganic perovskite solar cells (PSCs) is raising increasing interest in academia and industry, holding great promise for commercializing perovskite-based photovoltaics (PV). Despite the well-established use of vapor phase deposition processes in commercial manufacturing of thin-film photovoltaics and other optoelectronic applications, research on vapor phase processed PSCs is still underrepresented compared to their solution-based counterparts. Solution-processed PSCs still dominate the academic research, benefiting from fast optimization feedback and straightforward integration in modern research laboratories.
This contribution will present a recently published perspective (Ref 1) by an international team that conveys a balanced viewpoint from industry and academics on the prospects for vapor phase deposition of perovskite-based PV. The perspective highlights strategic opportunities of vapor phase deposition for the its commercialization of perovskite-based PV. In addition, the latest developments at the Karlsruhe Institute of Technology on vapor phase deposited PSCs and perovskite/Si tandem solar cells will be presented. With regard to co-evaporated PSCs, we have recently developed a comprehensive understanding of how interfacial hydrogen bonding impacts bulk perovskite properties, highlighting the potential for rational design of substrates to control organic cation incorporation (Ref. 2), and enabling us to incorporate our evaporated self-assembled monolayer hole transport layers (Ref. 3) into all-evaporated PSCs. In addition, our recent progress on sequentially evaporated and hybrid-processed PSCs will be summarized at the conference.

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.
