Аннотация

Building-integrated photovoltaics is an emerging field that demands approaches to deliver efficient and flexible photovoltaic cells at a low cost. In this work, high-quality single-walled carbon nanotube (SWCNT) films were utilized as an electrode for the hole-transport-layer (HTL)-free perovskite solar cells using a methodology compatible with scalable low-temperature roll-to-roll fabrication. We report a simple passivation strategy of the perovskite/SWCNT interface using methylammonium iodide, which dramatically enhances the performance of the cells, delivering power conversion efficiencies of up to 16.7%. We believe that the device configuration presented here will facilitate the development of a generation of bifacial perovskite solar cells for integrated photovoltaics and tandems.
