Fig. 5: The efficiency distributions of Prenucleation-PVSCs.

From: A prenucleation strategy for ambient fabrication of perovskite solar cells with high device performance uniformity

Fig. 5

Devices fabricated a at different levels of humidity, b using PbI2 reagents with different grades, c using DMF solvent with different grades and d using DMSO solvent with different grades. All the devices showed very similar standard deviations of PCE with the widely different device fabrication conditions and reagents, demonstrating the reproducibility and robustness of the prenucleation method. In the Box-Whisker Plots, the middle line refers to the median (the second quartile), the box goes from the first quartile to the third quartile, the upper/lower whisker refers to the maximum/minimum values of the data points.
