Recent developments in crystallization technology have shown that it is possible to produce silicon wit h particularly low defect density in a robust industrial manner. The underlying assumption for this project is therefore that future improvements can now most likely be reached by achieving a better control of contamination.
The primary objective of the proposed project is therefore to develop knowledge about impurity transport processes and impurity-defect interaction throughout the process of producing high performance multicrystalline silicon solar cells. The final aim is to provide reliable specific ations for the main components in the crystal growth system, i.e. silicon feedstock, crucibles and coating, as well as best practice guidelines for the process.
The project involves 4 industry and 3 research partners. The challenges will be approached th rough integrated use of experiments and mathematical modelling.
The competence built within this project aims at answering technologically critical questions and providing a better general understanding of the impurity transport through the value chain. These results are of high importance for the partners as well as the global photovoltaic industry and research community.
The project is financed by the Research Council of Norway (RCN)
