摘要
Perovskite solar cells(PSCs) have attracted tremendous attention recently.The industrial-scale doctor blading is a facile and low-cost technique to fabricate thin-film devices.In our previous work, we used doctor blading technique to fabricate high-quality perovskite thin film in air for efficient planar heterojunction(PHJ) PSCs, in which hole transporting layer(HTL) and electron transporting layer(ETL) were deposited by spin-coating process ~([1]).Herein, we demonstrate a methyammonium lead iodide precursor scheme coupled with solvent tuning to empower a prompt grain growth rate via doctor blading in ambient condition, resulting in semi-transparent perovskite thin film with superior morphology.Furthermore, both HTL and ETL are deposited by doctor blading process in ambient condition as well, leading to fully doctor-bladed PHJ-PSCs with a structure of ITO/PEDOT:PSS/CH_3NH_3PbI_3/PCBM/Ag and achieving a power conversion efficiency(PCE) up to 10.9% at an active area of 0.09 cm~2.The results pave a way towards fully printed PSCs in ambient condition and accelerate the commercialization.
