<p>Multiple-junction photoelectric device (1) comprises a substrate (2) on which a first conducting layer (3) is deposited, at least two elementary photoelectric devices (4, 6) of n-i-p or n-p configuration, on which a second conducting layer (7) is deposited, and at least one intermediate layer (5) provided between two adjacent elementary photoelectric devices (4, 6). Multiple-junction photoelectric device (1) comprises a substrate (2) on which a first conducting layer (3) is deposited, at least two elementary photoelectric devices (4, 6) of n-i-p or n-p configuration, on which a second conducting layer (7) is deposited, and at least one intermediate layer (5) provided between two adjacent elementary photoelectric devices (4, 6), where the intermediate layer (5) has, on the incoming light side, an top face (10) and, on the other side, a bottom face (11), the bottom face (11) having a peak to valley roughness greater than 150 nm, and in that the top (10) and bottom (11) faces have respectively a surface morphology comprising inclined elementary surfaces such that alpha 90bottom is smaller than alpha 90top by at least 3[deg] , preferably 15[deg] ; where alpha 90top is the angle for which 90% of the elementary surfaces of the top face (10) of the intermediate layer (5) have an inclination equal to or less than this angle, and alpha 90bottom is the angle for which 90% of the elementary surfaces of the bottom face (11) of the intermediate layer (5) have an inclination equal to or less than this angle. An independent claim is a process for producing a multiple-junction photoelectric device (1) above.</p> |
