Abstract: A solar cell apparatus 100 and a method for forming said solar cell apparatus 100, comprising a substrate 101, a n-type transparent conductive oxide (TCO) layer 102 deposited atop said substrate 101, a p-i-n structure 200 that includes a p-type layer 03,an i-type layer 104, an-type layer 105, a metal back layer 106 deposited atop said n-type layer 105 of the p-i-n structure 200. The n-type layer 105comprises n- type donors115including phosphorus atoms. The n-type donors115include oxygen atoms at an atomic concentration comprised between 5% and 25% of the overall atomic composition of the n-type layer 105.

Abstract: A solar cell apparatus (100) and a method (400) for forming said solar cell apparatus (100), comprising a substrate (101), a n-type transparent conductive oxide (TCO) layer (102) deposited over said substrate (101), a p-i-n structure (200) that includes a p-type layer (103), an i-type layer (104), said n-type layer (105), a metal back layer (106) deposited over said n-type layer (105) of the p-i-n structure (200). The p-type layer (103) comprises a p-type dopants graded multi-layers structure (3) that has a dopants concentration profile that varies as a function of the thickness of the p-type dopants graded multi-layers structure (3).
