Abstract:
1. A multiple-junction photoelectric device comprising a substrate on which a first conducting layer is deposited, at least two elementary photoelectric devices of p-i-n or p-n configuration, on which a second conducting layer is deposited, and at least one intermediate layer provided between two adjacent elementary photoelectric devices, wherein said intermediate layer has, on the incoming light side, a top face and, on the other side, a bottom face, said top and bottom faces having respectively a surface morphology comprising inclined elementary surfaces such that α 90bottom is smaller than α 90top by at least 3°, where α 90top is the angle for which 90% of the elementary surfaces of the top face of the intermediate layer have an inclination equal to or less than this angle, and α 90bottom is the angle for which 90% of the elementary surfaces of the bottom face of the intermediate layer have an inclination equal to or less than this angle.
