Abstract
Photovoltaic modules comprise solar cells having doped domains of opposite polarities along the rear side of the cells. The doped domains can be located within openings through a dielectric passivation layer. In some embodiments, the solar cells are formed from thin silicon foils. Doped domains can be formed by printing inks along the rear surface of the semiconducting sheets. The dopant inks can comprise nanoparticles having the desired dopant.
