Abstract

This invention relates an aluminum (Al) conductor paste formulation and its method of application on rear side passivated locally laser fired contacts (LFC). Such Back Surface Passivated (BSP) Si-solar cells include aluminum conductor paste formulations and methods of application on rear side passivated locally opened vias; dot or line geometry or combination thereof employing laser ablation or chemical etching methods. Such Back Surface Passivated Si- solar cells include dielectric layers of A1203, SiNx, Si02, SiC, α-Si, Si02/SiNx, A1203/SiNx, SiO2A12/SiNx. The Al-conductor paste of this invention achieves; (i) non-degradation of passivation stack, (ii) defect free surfaces and void free vias, (iii) a strong and uniform Back Surface Field (BSF) layer within dot vias and line vias.
