Abstract

Screen-printed Ag thick-film metallization is used in the photovoltaic industry for the front-side emitter contacts of crystalline silicon solar cells owing to its cost-effectiveness and high throughput. In order to obtain a better understanding for the formation of Ag crystallites at the paste/Si interface and the correlation between the electrical properties and microstructure of the contact, the firing treatment was carried out under various oxygen partial pressures (Po2) and the contact resistance was determined by a transfer length method (TLM) measurement. The present study results demonstrate strong dependences of the Ag crystallite formation and the contact resistance on Po2 in the firing ambience.
