Deeper understanding of Silicon (Si) crystallization in correlation and its correlation with photovoltaic properties
Although crystalline Si remains predominant at more than 90 % in PV solar cells, significant progress in terms of performance improvement and cost reduction is essential. In particular, the fundamental mechanisms of the Si crystallization are only imperfectly understood, which limits process improvement and delays the development of innovative processes.
Within this context, the CrysSaLID consortium has successfully carried out original or even unique fundamental research work, in connection with industrial questioning in order to deepen knowledge of Si crystallization and to develop predictive simulation tools. The formation of the crystal structure has been studied experimentally at different scales, in particular with a unique experiment with in situ X-ray imaging during solidification at high temperature. At the same time, 3D simulation models of crystal formation have been developed and validated experimentally.
