Nickel-Copper metallization for silicon solar cells offers a cost effective alternative to<br/><br/>traditional screen printed silver paste technology. The main objective of this work is to<br/><br/>study the formation of nickel silicide contacts with and without native silicon dioxide SiO2.<br/><br/>The effect of native SiO2 on the silicide formation has been studied using Raman<br/><br/>spectroscopy, Rutherford backscattering spectrometry and sheet resistance<br/><br/>measurements which shows that SiO<br/><br/>2<br/><br/>acts as a diffusion barrier for silicidation at low<br/><br/>temperatures of 350°C. At 400°C the presence of SiO2 results in the increased formation<br/><br/>of nickel mono-silicide phase with reduced thickness when compared to samples without<br/><br/>any native oxide. Pre and post-anneal measurements of Suns Voc, photoluminescence and<br/><br/>Illuminated lock in thermography show effect of annealing on electrical characteristics of<br/><br/>the device. The presence of native oxide is found to prevent degradation of the solar cells<br/><br/>when compared to cells without any native oxide. A process flow for fabricating silicon<br/><br/>solar cells using light induced plating of nickel and copper with and without native oxide<br/><br/>(SiO2) has been developed and cell results for devices fabricated on 156mm wafers have<br/><br/>been discussed.
