This paper presents a laser patterning technique which was developed for a high power solar cell with a through-Hole contact (THC), a new type structure. The performance for THC submodules is estimated by the numerical simulation based on a distributed equivalent circuit model. It is found that a 10% increase in the maximum output power can be expected using this structure. In order to form this THC structure, optical and three-dimensional thermal analysis of multi-layer structures was performed to determine the selective scribing conditions for each layer of the THC structure. It was found that each layer of the THC structure could be selectively scribed without any significant damage to the electric performances around the holes.
