Mullite-based substrates for polycrystalline silicon thin-film solar cells

摘要

The use of polycrystalline silicon thin-film oninexpensive ceramic substrates for solar cells is one of the mostpromising approaches to realize both their high performance andcost reduction. Mullite-based ceramics prepared from kaolin-alumina are appropriate for cost-effective substrates for thepolycrystalline silicon thin-film solar cells. They fulfillrequirements such as thermal and mechanical stability up to 1200deg C and no thermal expansion mismatch with silicon.
