Progress in the development of small-grained (10-100 ..mu..m) polycrystalline Si solar cells is hampered by the present poor knowledge of physical and chemical properties of grain boundaries and the lack of satisfactory processing techniques for junction formation. In the work discussed in this paper the authors have studied grain boundaries and their effects in polycrystalline silicon with grain sizes of 1-2 mm and in smaller grained material with grain sizes of 10 ..mu..m and 40-50 ..mu..m. Results for various recombination effects observed in the large-grained material are described and the influence of lithium passivation on the electrical properties of the small-grained material and on the characteristics of solar cells made from it are reported.
