Extended Data Fig. 2: Surface-potential mapping of the various TCOs.

From: Enhanced optoelectronic coupling for perovskite/silicon tandem solar cells

Extended Data Fig. 2

Atomic force microscopy surface morphology and KPFM surface-potential mapping of the various TCO layers before and after 2PACz coverage. Here Ra refers to the arithmetic average roughness of the potential values of the scanned area for the selected regions. The table reports the aligned surface potentials before and after HTL deposition.
