Summary: | A multiple-junction photoelectric device includes a substrate with a first conducting layer thereon, at least two elementary photoelectric devices of p-i-n or p-n configuration, with a second conducting layer thereon, and at least one intermediate layer between two adjacent elementary photoelectric devices. The intermediate layer has, on the incoming light side, opposite top and bottom faces, the top and bottom faces having respectively a surface morphology including inclined elementary surfaces so α90bottom is smaller than α90top by at least 3°, preferably 6°, more preferably 10°, and even more preferably 15°; where α90top 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 α90bottom 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. |
