Abstract
Alumina and mullite substrates for the development of crystalline silicon solar cells were produced by water-based tape-casting with acryl latex binder. The suspension composition was optimized by assessment of the reological properties of alumina suspensions. The optimal dispersant concentration for highest maximal solid loading increases with increasing content of latex binder. It was found that thicker tapes could be produced due to decreasing sensitivity for crack formation if a higher ratio of binder to ceramic is used.
