Perovskite solar cells (PSCs) have attracted intensive attention due to their ever-increasing power conversion efficiency (PCE), low-cost materials constituents, and simple solution fabrication process. In printable mesoscopic PSCs, the perovskite is deposited on a triple-layer scaffold, made of screen printed mesoporous TiO2 layer, ZrO2 spacer layer and carbon electrode; such devices use carbon electrodes to replace the noble metal back contacts and do not require a hole-conducting layer.
Controlling the crystallization of organic–inorganic hybrid perovskite is of vital importance to achieve high performing perovskite solar cells. The growth mechanism of perovskites has been intensively studied in devices with planar structures and traditional structures. However, for the printable mesoscopic perovskite solar cells, it is difficult to study the crystallization mechanism of perovskite owing to the complicated mesoporous structure. In this talk, I am going to share the development of the printable mesoscopic PSCs and how we manage to control the crystallization in mesopores.
