High efficiency n-type silicon solar cells featuring passivated contact to laser doped regions

Yang, Xinbo; Bullock, James; Bi, Qunyu; Weber, Klaus


Minimizing carrier recombination at cell contacts becomes increasingly important for reaching high efficiency. In this work, the passivated contact concept is implemented into n-type silicon solar cells with laser-processed local back surface fields. The passivation and contact characteristics of the SiO2/amorphous silicon (a-Si:H) stack on localized laser doped n+ regions are investigated. We find that the SiO2/a-Si:H stack provides not only good passivation to laser doped n+ regions but also...[Show more]
