Architecture of Electron Transport Layer for Perovskite Solar Cell


The emergence of perovskite solar cells (PSCs) recently brings a new hope to the solar cell industry due to their incredible improvement of power conversion efficiency (PCE) exceeding 20.0 % within seven years of tremendous researches. The efficiency and stability of PSCs depend strongly on the morphology and type of materials selected as electron transport layer (ETL) in the device. In this review, the functions of ETL based on titania (TiO2) in n-i-p architecture PSCs including planar heterojunction and mesoporous-structured devices are reviewed in terms of device performance and stability. Studies found that application of suitable fabrication techniques and manipulation of nanostructural properties of TiO2 are crucial factors in ameliorating the short-circuit current density, JSC and fill factor, FF of PSCs. On top of that, the effect of substituting TiO2 with other potential inorganic materials like zinc oxide (ZnO), tin oxide (SnO2), ternary metal oxides and metal sulphides as well as organic semiconductors including fullerene, graphene and ionic liquid towards photovoltaic properties and stability of the devices are also elaborated and discussed. Meanwhile, utilization of non-electron transport layers (non-ETLs) such as alumina (Al2O3) and zirconia (ZrO2) as mesoporous scaffold in PSCs is found enhancing the open-circuit voltage, VOC of the devices.
