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.
