Customer ServiceThese finding can suggest that boron content in aluminum pastes is supportive to improve the bulk quality of silicon solar cells. However, poor performance of such pastes on solar cell fabrication is needed to be investigated further for higher efficiencies. 1.
Solar cells with developed aluminum pastes show better performance than that of the cells with C-Al-paste. Pseudo efficiency of the cells with B-free-Al-paste and Al-B-paste BSFs were 18.3% and 18.0%, respectively. Table 3.
In case of boron included aluminum pastes, besides increasing the alloying concentration, addition of boron content into the aluminum can alter the gettering effect at the same time. However, production of such a paste and adaptation of it to the silicon solar cells is necessary.
