text: Finally, an InGaP hetero-layer between the p-Ge layer and the InGaAs layer can be added in order to create automatically the n-Ge layer by scattering during MOCVD growth and increase significantly the quantum efficiency QE(λ) of the bottom cell.
text: PERC solar cells have an extra layer within the back side of the cell.
text: —a layer on the back of the cell can be added to reflect sunlight of selected wavelengths, sending it back for a second pass through the active layers.
