Figure 2From: Application of hybrid blocking layers in solid-state dye-sensitized solar cellsLamella of the hybrid blocking layer between Pt and Si prepared with a FIB: TEM image (a) and TiO2 mapping by ESI (b). In the ESI image TiO2-rich areas are colored red, areas of medium TiO2-concentration are colored green and areas without TiO2 are colored blue. Back to article page
