Characteristics of an all-implanted p+-n-n+solar cell

This work presents the main electrooptical parameters of a p⁺-n-n⁺single-crystalline silicon solar cell, whose front p⁺-n junction and the backside n-n⁺contact were fabricated through masked ion implantation of boron (¹¹B+) and phosphorus (³¹p+), respectively. The distinctive feature of the cells consists of the use of the front junction silicon dioxide mask as an AR layer in the finished devices.
