Improving the Stability of Ambient processed, SnO2-Based, Perovskite Solar Cells by the UV-treatment of Sub-Cells
Abstract
SnO2 is nowadays the widely preferred material as an electron transport layer (ETL) in most of the n-i-p planar perovskite solar cells (PSCs) owing to their facility for ambient and low temperature processing. Its wide bandgap is claimed to facilitate device stability against UV light. Most of the reports published so far study device stability on full cells with ubiquitous use of Spiro-OMeTAD as a hole-transport layer. With Spiro-OMeTAD’s known instability, it is difficult to discern the role of SnO2 on the stability of the PSCs. This report exclusively investigates the role of slot-die coated SnO2 on air processed planar PSCs by analyzing sub cells (ITO/SnO2/perovskite) under UV-exposure.Results from UV vis spectroscopy, depth profiling using X ray diffraction measurement at grazing incidence mode (GIXRD) and X-ray Photoelectron Spectroscopy (XPS), photoluminescence spectroscopy measurements show that UV treatment of ITO/SnO2/perovskite has led to a reduced electron transfer to the SnO2 and a gradual increase in the amount of PbI2 towards the perovskite surfaces. Subsequently, the hole transporting layer (HTL) and electrodes were applied on SnO2/perovskite interfaces (UV-treated and non-UV treated) and complete devices were fabricated.Device performance was compared and analyzed through J-V curves and maximum power point (MPP) tracking. Results show that device built on UV-treated SnO2/perovskite interface shows better stability attributed to the presence of excess PbI2 resulting in a passivation effect. As a basis for our stability studies, we present also a section on a slot-die coating of SnO2, highlighting challenges in uniform film formation and potential solutions with the use of a polymeric additive.
