Abstract

A cell assembly includes a first doped region. The first doped region includes a first passivated contact region disposed on the silicon substrate, and a second passivated contact region disposed on the first passivated contact region. The first passivated contact region includes a first doped layer, a first passivation layer, and a second doped layer. The second passivated contact region includes a second passivation layer and a third doped layer. The second passivated contact region includes an opening for connecting a conductive layer of the solar cell to the first passivated contact region.
