Abstract (en)
[origin: WO2022167018A1] The invention relates to a layered structure for solar cells, preferably for high-temperature solar cells, having tunnel oxide-passivated contacts on the front side or on the front and back side of the solar cells consisting of at least one tunnel oxide layer, in particular a silicon oxide layer SiOx where x = 1-2 or an aluminum oxide layer AlOx where x = 1-2 and a μc-SiCx(n) layer, where x is 50.5, preferably ≥ 0.5 to 0.9, wherein (n) = n-doped and wherein in an advantageous embodiment μc-SiCx(n) is a hydrogenated μc-SiCx:H (n) layer. The layered structure according to the invention may preferably be configured as a front-side contact of a solar cell, preferably a high-temperature solar cell. The invention further relates to a process for producing the layered structure and to a solar cell containing the layered structure according to the invention as a front-side or as a front-side and back-side contact.
