• Thick Al films are used widely as the backside electrode material of Si solar cells. The formation of Al and a back surface field reduce the back-surface recombination and improve the cell performance. This study examined the characteristics of Si solar cells with the addition of frits and additives to Al pastes after firing. The reactions among Al powders, frits and additives were studied. The wetting behavior between each powder (Al powder, frit, additive) and Si, Al substrates was also measured as a function of the temperature. These preliminary studies show that the frits affect the adhesion between Al and Si. In addition, the proper additives prevent the bowing of Si wafer.
