Abstract
Expression of concern for ‘Null current hysteresis for acetylacetonate electron extraction layer in perovskite solar cells’ by Abd. Rashid bin Mohd Yusoff et al., Nanoscale, 2016, 8, 6328–6334, https://doi.org/10.1039/C5NR06234A.
Nanoscale is publishing this expression of concern in order to alert readers that concerns have been raised regarding the integrity of the XRD data in the top three traces in Fig. 1d. Due to the time elapsed, which is more than 10 years, the authors are not able to provide the raw data. An expression of concern will continue to be associated with the article until a conclusive outcome is reached.
