Large Grain-Based Hole Blocking Layer Free Planar-type Perovskite Solar Cell with Best Efficiency of 18.20 % |
| 초록 |
There remains tremendous interest in perovskite solar cells (PSCs) in the solar energy field; the certified power conversion efficiency (PCE) now exceeds 20 %. Along with research focused on enhancing PCE, studies are also underway concerning PSC commercialization. It is crucial to simplify the fabrication process and reduce the production cost to facilitate commercialization. Herein, we successfully fabricated highly efficient hole-blocking layer (HBL)-free PSCs through vigorously interrupting penetration of hole-transport material (HTM) into FTO by large grain based-CH3NH3PbI3 (MAPbI3) film, thereby obtaining a PCE of 18.20 %. Our results advance the commercialization of PSC via a simple fabrication system and a low-cost approach in respect of mass production and recyclability. |
