A Crystal Engineering Approach for Perovskite Solar Cells and Modules Fabrication out of the Glove Box

Abstract

In the present work we used some crystallization trends which could be classified as Crystal Engineering (CE) methods, for deposition of a pure cubic-phase thin film of CH3NH3PbI3 at the surface of mesoporous TiO2 layer. Accordingly, by using the CE approach in air, we fabricated high efficiency perovskite solar cells (PSC) and perovskite solar modules (PSM) utilizing several Hole Transport Layers (HTLs). The results show that the CE approach remarkably improved the device performance reaching a power conversion efficiency of 17%, 16.8% and 7% for spiro-OMeTAD, P3HT and HTL free, respectively. Furthermore, perovskite solar modules (active area of 10.1 cm2), could reach an overall efficiency of 13% and 12.1% by using spiro-OMeTAD and P3HT as HTLs, respectively. Sealed modules showed promising results in terms of stability maintaining 70% of the initial efficiency after 350 hours of light soaking at maximum power point.
