  • Abstract There are two kinds of making solar cell, one is that a polysilicate wafer makes p-n junctions by etching and diffusion methods, other is depositing lines of polysilicate thin film on a substrate, the latter could save cost of raw materials of silicate. If we use foreign substrates to substitute for polysilicate wafer substrates, the cost could save much more. But thermal expansion coefficient of ceramic substrates is much larger than silicate, so we chose a suitable glasses as a interlayer(enduring CVD temperature、 small roughness、 CTE between polysilicates and substrates). CaO-Al2O3-SiO2 glass as a main component add different elements to modify thermal behavior of glasses, matching the ceramic substrates.This thesis select B2O3、GeO2、La2O3 and Ba2O3 adding to glasses to modified the thermal behavior.Adding three front elements for glasses would decrease viscosity;Adding last element would increase viscosity. From the sigh of the thermal expansion behavior, adding B2O3 and Ba2O3 could decrease the coefficient of thermal expansion, and adding GeO2 and La2O3 could increase the coefficient of thermal expansion.
