Samenvatting:
For a successful development of thin-film crystalline silicon solarcells, both the availability of cheap substrates and a suitable deposition technique are required. To ease the introduction of thin-film silicon solar cells in commercial process lines, substrates which can withstand temperatures up to 900C are preferred. Because of additional demands such as low-cost, non-toxicity and high strength, ceramics are good candidates to serve as substrate materials. To facilitate nucleation, and to match the silicon thermal expansion coefficient, the production of silicon based ceramics by the potentially low-cost tape casting method is being investigated. To increase the density and strength of the substrates, Al and Sialon were used as additives. To investigate nucleation and layer growth on the ceramic substrates, Liquid Phase Epitaxy has been chosen as the deposition technique. Although we can grow easily from aluminium melts, we focus on (doped) indium and tin melts. The results indicate that layer growth on the substrates is possible, but no continuous layers have been realised yet. 7 figs., 17 refs.
