MULTIPLE-JUNCTION PHOTOELECTRIC DEVICE AND ITS PRODUCTION PROCESS

摘要

The device (1) has an intermediate layer (5) including top and bottom faces (10, 11) presenting morphology of a surface comprising inclined elementary surfaces such that difference between first and second angles is higher than or equal to 15 degrees. The first angle is a third angle for which 90 percentages of the elementary surfaces of the top face have an inclination equal to or less than the third angle, and the second angle is a fourth angle for which 90 percentages of the elementary surfaces of the bottom face have an inclination equal to or less than the fourth angle. An independent claim is also included for a method for realization of a multiple-junction photoelectric device.
