a–c, SEM cross-section micrographs of the front and rear side of planar (a), nanotextured (b) and nanotextured + RDBL (c) PSTSCs. c-Si, crystalline silicon. d, AFM image of the nanostructured silicon bottom cell front side prior to the deposition of the contact layers. e, Photographs of the final PSTSC with a blue active area in between the front-side silver ring of approximately 1 cm2 (left) and the RDBL on the rear side (right).
