A humidity resistant and versatile fabrication method for the production of very high quality, organic-inorganic perovskite films, solar cells modules is presented. By using ethyl acetate as an anti-solvent during deposition, with power conversion efficiencies (PCEs) up to 15% were fabricated in a 75% relative (RH) environment. Ethyl acts moisture absorber spin-coating, protecting sensitive intermediate phases from airborne water film formation annealing. We have demonstrated manufacture 50...
Perovskite photovoltaics have shown great promise in device efficiency but also the of scalability through solution-processed manufacture. Efforts to scale perovskites been taken printable mesoporous scaffolds and slot die coating flexible substrates roll-to-roll (R2R). However, date there has no demonstration entirely R2R-coated devices due lack a compatible solution-processable back electrode; instead, high-value evaporated metal contacts are employed as post process. Here, this study,...
Abstract Perovskite solar cells based on an all printable mesoporous stack, made of overlapping titania, zirconia, and carbon layers, represent a promising device architecture for both simple, low‐cost manufacture, outstanding stability.

Near infrared sintering in less than 25 seconds for enhanced commercial viability of screen printed perovskite solar cells.
The fully printable carbon triple-mesoscopic perovskite solar cell (C-PSC) has already demonstrated good efficiency and long-term stability, opening the possibility of lab-to-fab transition. Modules based on C-PSC architecture have been reported and, at present, are achieved through accurate registration each patterned layers using screen-printing. this approach were with geometric fill factor (g-FF) as high 70%. Another to create interconnects, so-called scribing method, was achieve more...

Organic–inorganic lead halide perovskite materials are an attractive candidate for low-cost thin-film photovoltaics but in order to successfully rival other technologies, it is critical focus research on addressing the potential bottlenecks commercialisation. The conventional hole transporter spiro-OMeTAD and evaporated gold contact unsuitable commercialisation due cost. This study introduces a method fabricating devices without spiro-OMeTAD. Instead, PEDOT:PSS was applied directly material...
