Abstract

Glasses with compositions (40 - x)PbO - xZnO - 60(B₂O ₃ - SiO₂) (x = 5, 10, 15, 20) have been prepared. Substitution of ZnO for PbO increased glass bandgap (E_g) and crystallization ability greatly. Crystalline phases of bulk glasses after rapid thermal processing (RTP) were identified by X-ray diffraction (XRD). Transmission line model (TLM) was employed to measure the electrical performance of Ag electrodes screen printed on polycrystalline Si substrates using Ag thick-film pastes and by RTP. The conductivity (σ) decreased while specific contact resistance (ρ_c) was not monotonic varied with increasing ZnO content. The correlation between electrical performance and glass barrier formed on the Ag gridline and Si emitter interface has been investigated.
