| Summary: | The evolution of microstructure and electrical properties of silver-based thick-film
metallizations of silicon solar cells prepared by infrared firing processes has been
investigated. The performance of the cells are shown to be dependent on several
dynamical and diffusive phenomena. In particular, the sintering of silver grains, silver
diffusion into the glass, and the flow of glass at the metal/silicon interface strongly
affect important characteristics of the cells such as sheet and contact resistivities and
the adhesion of fingers and bus bars. The existance of an optimum value of the peak
firing temperature is observed and explained in terms of competitive phenomena
occurring at the metal/silicon interface. Moreover it is shown that IR firing treatments
require a careful consideration of the sequence of printing and firing steps. The
features of heat treatments performed in conveyor belt furnances using Joule and
infrared sources are compared. |
