Abstract

Effects of screen-printed aluminum-alloyed front emitter (AAFE) on characteristics of screen-printed N-type silicon solar cells (SPNSSC) were presented. The sheet resistances of AAFE in SPNSSCs can be modified by the firing temperature, the firing time, the waiting time, and the etching time of the KOH solution. The results show that the sheet resistance decreases with increasing the firing time, and the firing temperature. On the other hand, the sheet resistance increases with increasing the waiting time as well as the etching time of the KOH solution. Moreover, the larger thickness of AAFE can be achieved by the increase of the firing temperature and time. The optimum conversion efficiency can be obtained by suitably turned process parameters.
