| Research Abstract |
The microstructural control condition of silicon (Si) using a laser power was evaluated for the purpose of the development of characteristics and the reduction of the cutting waste for the multi-crystalline silicon solar battery. Though the latent heat of fusion of Si is extremely high, it was revealed that the Si particles are dissolved and solidified in a few seconds by irradiating the laser of a relatively long pulse, Si particle of ten to several hundred micrometers size is obtained, and the microstructure of Si is influenced by the heterogeneous nucleation. Furthermore, it is showed that the optimization of temperature distribution, the atmosphere and the cooling control of Si particle and the substrate are important, since the thermal stress between solidification structure and the heated area causes to initiate the clack at the production of film type multi-crystalline Si.
