Correction to: Nature Energy https://doi.org/10.1038/s41560-018-0125-0, published online 2 April 2018.

In the version of this Article originally published, in the ‘Rear-side light trapping’ paragraph of the Methods section, the values of depth and fill factor were incorrectly given as 350 nm and 50%, respectively; instead, the values should have read 250 nm and 60%. This has now been corrected.
