Fabrication of Perovskite Solar Cells by the Smart Stacking Process

Abstract

The most commonly used process for fabricating perovskite solar cells is based on wet chemistry, which greatly limits the choice of materials suitable for optimizing the performance of the device. We developed a new approach for the fabrication of perovskite-based solar cells. In the smart stacking process, the perovskite solar cell was assembled by stacking two pieces of perovskite films prepared separately. A working perovskite solar cell was developed with PCE = 0.78% and the perovskite layer was analyzed with XRD and SEM. Our findings showed new ways to address some of the major fabrication challenges associated with the commercialization of perovskite solar cells.
