Abstract

A spin-coating-free fabrication sequence has been developed for the fabrication of highly efficient organic-inorganic halide perovskite solar cells (PSCs). A novel blow-drying method is demonstrated to be successful in depositing high quality mesoporous TiO₂ (mp-TiO₂), methylammonium lead halide (CH₃NH₃PbI₃) perovskite and spiro-MeOTAD layers. When combined with compact TiO₂ (c-TiO₂) deposited by spray pyrolysis which is also a spin-coating-free process, a stabilized power conversion efficiency exceeding 17% can be achieved for the glass/FTO/c-TiO₂/mp-TiO₂/ CH₃NH₃PbI₃/spiro-MeOTAD/Au device. This is the highest efficiency for PSCs fabricated without the use of spin-coating to our knowledge. This method provides a pathway towards a scalable process for fabricating high-performance, large area and reproducible PSCs.
