Abstract Over the past decade, perovskite solar cells have travelled an amazing way towards high efficiency. However, a major roadblock remaining is the operational stability, while achieving technological maturity and proving real-world stability is crucial to gain trust among investors. In that sense, it is of high interest to be able to predict the operational lifetime, which needs to be in the range of years or decades, within an experimentally reasonable timeframe. Yet, peculiarities of perovskite solar cells’ ageing behaviour lead to severe difficulties in translating the results of indoor tests to their outdoor counterpart. In particular, transient processes cause diverse results among different ageing tests.Here, for the first time, we show a complete set of constant illumination indoor testing, cycled illumination indoor testing and real-world outdoor testing on equal in-house devices. Exemplarily, we compare two different types of perovskite solar cells, in which only the hole-transport layer is varied. Despite this small change, the devices show distinctly different transient behaviour. In either case, the commonly used constant illumination experiments fail to predict the outdoor behaviour of the cell. Yet, we observe a good correlation between the cycled illumination test and the outdoor behaviour of one of the two solar cells, while this is not the case for the other system. This result highlights the urge for further research on how to perform meaningful accelerated indoor tests to predict the outdoor lifetime of perovskite solar cells.

Due to the rough surface of fluorine-doped tin oxide (FTO) conductive glasses, it is challenging to fabricate fully covered ultra-thin hole-transport layer (HTL) with thickness under 100[Formula: see text]nm by a simple solution-processed method. Yet, the quality of HTLs play a key role in determining photovoltaic performance of the inverted planar perovskite solar cells (PSCs) owing to their important functions for effectively extracting holes, blocking electrons, suppressing dark reaction, and so on. Here, we report a facile nickel-containing organic sol (Ni–Sol) route to fabricate fully covered 46[Formula: see text]nm thick NiO HTLs for efficient inverted planar PSCs. Comparing with the pre-synthesized NiO nanocrystals solution, the Ni–Sol is easier to spread around the rough outline of FTO to achieve higher surface coverage. Through optimizing the concentration of nickel-containing organic sol, the champion performance of the inverted planar PSCs can be achieved because of the high transparency and good hole-transport dynamics of the optimized NiO film. This work demonstrates the advanced Ni–Sol route for preparing efficient inverted planar PSCs by the simple solution-processed method.
